The Planets & Dwarf Planets

Planetary Reports generated by "TheSkyX" software. These reports provide predicted data for the planets for the first of each month for the current year. The rise and set times for the Sun and the Moon for each day of the month as well as meteor shower radiants are also included in the reports. These reports have been optimized for the Denver, Colorado location, however, the times will be approximate for other locations on Earth.

(All times are local unless otherwise noted.)

Planetary Highlights for November

"With the seven major planets on display, this month is a busy time for observers. Jupiter and Saturn continue their dramatic pairing in the southern sky. Mars remains near its peak and begins its retreat from Earth; catch it early in the month while you can. Neptune is near a bright star, while Uranus remains in a sparse region of sky and is up all night. The predawn sky hosts Venus and Mercury, a treat for early risers.

The window for observing Jupiter and Saturn is narrowing. In early November, the planets set an hour before midnight. Four weeks later, they're gone by 9:30 P.M. local time. The longer nights afford an early start — the best time to begin observing is as soon as twilight starts and the Sun has gone down." Astronomy Magazine, November 2020, P. 32.

Mercury

Is stationary on the 3rd. Mercury is at greatest western elongation (19°) on the 10th. Mercury rises at 5:21 a.m. on the 1st and about 6:11 a.m. by month's end. Look for Mercury low to the east about 30 minutes to an hour before sunrise during the month. Mercury moves from the constellation of Virgo into Libra shining at magnitude -0.7 on the 15th.

Venus

Rises at 3:36 a.m. on the 1st and about 4:42 a.m. by month's end. Look for Venus in the east before sunrise. Venus moves from the constellation of Virgo into Libra shining at magnitude -3.9 on the 15th.

Earth

Daylight Saving Time ends for most of the U.S. on November 1st at 2 a.m. local time.

Mars

Sets at 4:36 a.m. on the 1st and about 2:45 a.m. by month's end. Mars is stationary on the 15th. Mars can be viewed almost all night long. Mars is still near its best viewing for the year but dims quickly during the month. Look for Mars high in the east soon after sunset. Mars is in the constellation of Pisces shining at magnitude -1.7 on the 15th.

Jupiter

Sets at 9:28 p.m. on the 1st and about 7:55 p.m. by month's end. Look for Jupiter soon after sunset to the southwest. Jupiter will be one of the first objects to be spotted to the southwest once the Sun sets. Jupiter is in the constellation of Sagittarius shining at magnitude -2.1.

Saturn

Sets at 9:53 p.m. on the 1st and about 8:06 p.m. by month's end. As with Jupiter, look for Saturn in the evening sky after sunset to the southwest. Saturn is in the constellation of Sagittarius shining at magnitude 0.6.

Uranus

Rises at 4:48 p.m. on the 1st and around 2:46 p.m. by month's end. Uranus is visible in the evening almost night long. Look to the south-southeast soon after sunset to spot Uranus. Uranus is in the constellation of Aries shining at magnitude 5.7.

Neptune

Sets at 2:18 a.m. on the 1st and about 12:19 a.m. by month's end. Neptune is stationary on the 29th. Neptune can be spotted to the south once the skies darken. Neptune is in the constellation of Aquarius shining at magnitude 7.9.

Dwarf Planets

Ceres

Sets at 12:18 a.m. on the 1st and around 10:46 p.m. by month's end. Ceres can be spotted to the southwest soon after sunset. Ceres is in the constellation of Aquarius shining at magnitude 8.9.

Pluto

Sets at 9:32 p.m. on the 1st and around 7:36 p.m. by month's end. Pluto now precedes Jupiter and Saturn by a few minutes. Pluto is in the constellation of Sagittarius shining at magnitude 14.8.

As always, good luck at spotting Neptune, Ceres and Pluto, a large telescope and dark skies will be needed.

Astronomical Events

Meteor Showers

  • The Leonids - The duration of this shower covers the period of Nov. 14-20. Maximum occurs on Nov. 17. The maximum hourly rate typically reaches 10-15, but most notable are periods of enhanced activity that occur every 33 years - events that are directly associated with the periodic return of comet Tempel-Tuttle. During these exceptional returns, the Leonids have produced rates of up to several thousand meteors per hour. The Leonids are swift meteors, which are best known for leaving a high percentage of persistent trains.

    Prospects for the shower are good since the Moon will not interfere. The best time to observe the Leonids will be between 3 a.m. and 6 a.m. local time for the duration of the shower.

    Meteor Shower Radiant Report

    For more information about Meteor Showers, visit Gary Kronk's Meteor Showers Online web page.

    Meteor Scatter (or Meteor burst communications) - "is a radio propagation mode that exploits the ionized trails of meteors during atmospheric entry to establish brief communications paths between radio stations up to 2,250 kilometres (1,400 mi) apart." Tune your shortwave or your HF amateur radio to 54.310 MHz SSB and see if you can hear any pings. Try other frequencies as well... 6m FT8 digital - 50.313 Mhz & 50.276 Mhz, JP-65 digital mode and the carrier frequencies of the lower VHF bands for TV channels 2, 3 & 4.

    Meteor Rx How-To by Terry Bullett (WØASP)

  • Comets

  • "The early evening comet cruise continues. Unlike the narrow loops of most icy visitors, Comet 88P/Howell's 5.5-year orbit is nestled between that of Mars and Jupiter. Like Mars after opposition, it runs on the racetrack just outside ours, barely losing speed. As a bonus for northerners, Howell climbs higher in the sky, thanks to Earth's tilt.

    Ensure you're set up early with an unobstructed southwest horizon. As time ticks past nautical twilight, Howell is only 20° high. The dark sky window opens for one hour on November 4th, but widens thereafter. At midmonth, it glides 3.5° beneath gas giants Jupiter and Saturn at almost 1° per day. By the 18th, the Moon's light becomes an issue once again." Astronomy Magazine, November 2020, P.38.

    NASA Contacts Voyager 2 Using Upgraded Deep Space Network Dish

    Full Article & Images

    "The only radio antenna that can command the 43-year-old spacecraft has been offline since March as it gets new hardware, but work is on track to wrap up in February.

    On Oct. 29, mission operators sent a series of commands to NASA's Voyager 2 spacecraft for the first time since mid-March. The spacecraft has been flying solo while the 70-meter-wide (230-foot-wide) radio antenna used to talk to it has been offline for repairs and upgrades. Voyager 2 returned a signal confirming it had received the "call" and executed the commands without issue."

    Juno - October 27, 2020
    Juno Data Indicates 'Sprites' or 'Elves' Frolic in Jupiter's Atmosphere

    Full Article & Images

    "An instrument on the spacecraft may have detected transient luminous events — bright flashes of light in the gas giant's upper atmosphere.

    New results from NASA's Juno mission at Jupiter suggest that either "sprites" or "elves" could be dancing in the upper atmosphere of the solar system's largest planet. It is the first time these bright, unpredictable and extremely brief flashes of light — formally known as transient luminous events, or TLE's — have been observed on another world. The findings were published on Oct. 27, 2020, in the Journal of Geophysical Research: Planets.

    Scientists predicted these bright, superfast flashes of light should also be present in Jupiter's immense roiling atmosphere, but their existence remained theoretical. Then, in the summer of 2019, researchers working with data from Juno's ultraviolet spectrograph instrument (UVS) discovered something unexpected: a bright, narrow streak of ultraviolet emission that disappeared in a flash."

    New Horizons - August 27, 2020
    Pluto Crater Named for New Horizons Pathfinder Tom Coughlin

    Full Article & Images

    "In nearly four decades as an engineer and manager at the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, Tom Coughlin was known for leading teams through tough assignments with dedication, enthusiasm and just the right amount of humor. And in the early 2000s he applied all of those traits as the proposal manager and first project manager for New Horizons, helping to shepherd the fledgling mission from design through flight confirmation.

    Now, Coughlin is being honored for those roles with a tribute on the very world New Horizons was built to explore. Coughlin crater is one of four newly named features on the surface of Pluto, which New Horizons flew past in July 2015."

    JMARS

    JMARS is an acronym that stands for Java Mission-planning and Analysis for Remote Sensing. It is a geospatial information system (GIS) developed by ASU's Mars Space Flight Facility to provide mission planning and data-analysis tools to NASA's orbiters, instrument team members, students of all ages, and the general public.

    Laboratory for Atmospheric and Space Physics

    "The Laboratory for Atmospheric and Space Physics (LASP) at the University of Colorado Boulder (CU) began in 1948, a decade before NASA. We are the world's only research institute to have sent instruments to all eight planets and Pluto.

    LASP combines all aspects of space exploration through our expertise in science, engineering, mission operations, and scientific data analysis. As part of CU, LASP also works to educate and train the next generation of space scientists, engineers and mission operators by integrating undergraduate and graduate students into working teams. Our students take their unique experiences with them into government or industry, or remain in academia to continue the cycle of exploration.

    LASP is an affiliate of CU-Boulder AeroSpace Ventures, a collaboration among aerospace-related departments, institutes, centers, government labs, and industry partners."

    LASP/MAVEN - September 14, 2020
    LASP scientist determine that volcanic ash may have a bigger impact on the climate than we thought

    Full Article & Images

    "When volcanos erupt, these geologic monsters produce tremendous clouds of ash and dust--plumes that can blacken the sky, shut down air traffic and reach heights of roughly 25 miles above Earth's surface.

    A new study led by the University of Colorado Boulder suggests that such volcanic ash may also have a larger influence on the planet's climate than scientists previously suspected."

    Mars 2020 - Perseverance - October 27, 2020
    NASA's Perseverance Rover Is Midway to Mars

    Full Article & Images

    "Sometimes half measures can be a good thing — especially on a journey this long. The agency's latest rover only has about 146 million miles left to reach its destination.

    NASA's Mars 2020 Perseverance rover mission has logged a lot of flight miles since being lofted skyward on July 30 — 146.3 million miles (235.4 million kilometers) to be exact. Turns out that is exactly the same distance it has to go before the spacecraft hits the Red Planet's atmosphere like a 11,900 mph (19,000 kph) freight train on Feb. 18, 2021.

    "At 1:40 p.m. Pacific Time today, our spacecraft will have just as many miles in its metaphorical rearview mirror as it will out its metaphorical windshield," said Julie Kangas, a navigator working on the Perseverance rover mission at NASA's Jet Propulsion Laboratory in Southern California. "While I don't think there will be cake, especially since most of us are working from home, it's still a pretty neat milestone. Next stop, Jezero Crater." "

    Mars Science Laboratory - Curiosity - August 3, 2020
    8 Martian Postcards to Celebrate Curiosity's Landing Anniversary

    Full Article & Images

    "NASA's Curiosity Mars rover has seen a lot since Aug. 5, 2012, when it first set its wheels inside the 96-mile-wide (154-kilometer-wide) basin of Gale Crater. Its mission: to study whether Mars had the water, chemical building blocks, and energy sources that may have supported microbial life billions of years ago.

    Curiosity has since journeyed more than 14 miles (23 kilometers), drilling 26 rock samples and scooping six soil samples along the way as it revealed that ancient Mars was indeed suitable for life. Studying the textures and compositions of ancient rock strata is helping scientists piece together how the Martian climate changed over time, losing its lakes and streams until it became the cold desert it is today."

    Mars Reconnaissance Orbiter Mission - October 1, 2020
    AI Is Helping Scientists Discover Fresh Craters on Mars

    Full Article & Image

    "It's the first time machine learning has been used to find previously unknown craters on the Red Planet.

    Sometime between March 2010 and May 2012, a meteor streaked across the Martian sky and broke into pieces, slamming into the planet's surface. The resulting craters were relatively small — just 13 feet (4 meters) in diameter. The smaller the features, the more difficult they are to spot using Mars orbiters. But in this case — and for the first time — scientists spotted them with a little extra help: artificial intelligence (AI)."

    Mars Odyssey Orbiter - June 8, 2020
    Three New Views of Mars' Moon Phobos

    Full Article and Images

    "Three new views of the Martian moon Phobos have been captured by NASA's Odyssey orbiter. Taken this past winter and this spring, they capture the moon as it drifts into and out of Mars' shadow.

    The orbiter's infrared camera, the Thermal Emission Imaging System (THEMIS), has been used to measure temperature variations across the surface of Phobos that provide insight into the composition and physical properties of the moon. Further study could help settle a debate over whether Phobos, which is about 16 miles (25 kilometers) across, is a captured asteroid or an ancient chunk of Mars that was blasted off the surface by an impact."

    Journey to Mars - InSight - Revealing the Heart of Mars - October 16, 2020
    NASA InSight's 'Mole' Is Out of Sight

    Full Article and Images

    "NASA's InSight lander continues working to get its "mole" — a 16-inch-long (40-centimeter-long) pile driver and heat probe — deep below the surface of Mars. A camera on InSight's arm recently took images of the now partially filled-in "mole hole," showing only the device's science tether protruding from the ground.

    Sensors embedded in the tether are designed to measure heat flowing from the planet once the mole has dug at least 10 feet (3 meters) deep. The mission team has been working to help the mole burrow to at least that depth so that it can take Mars' temperature.

    The mole was designed so that loose soil would flow around it, providing friction against its outer hull so that it can dig deeper; without this friction, the mole just bounces in place as it hammers into the ground. But the soil where InSight landed is different than what previous missions have encountered: During hammering, the soil sticks together, forming a small pit around the device instead of collapsing around it and providing the necessary friction."

    Interactive selection of raw images taken by the cameras aboard InSight.
