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

"Most amateur astronomers prefer nighttime viewing, avoiding daylight like the vampires of lore. But it shouldn't take much convincing to make an exception this month and watch Mercury pass directly in front of the Sun. As the fourth of 14 such transits this century, it's a rare event you won't want to miss." Astronomy Magazine, November 2019, p.36.

Venus and Jupiter are prominent in the evening sky soon after sunset. Saturn trails behind in the southwest by a few hours. Uranus is still near peak and is visible most of the night. Mars brightens in the morning sky as it continues to appear higher in the early morning.


Transits the Sun on the 11th. Mercury is in inferior conjunction on the 11th (10 a.m. EST). Mercury is stationary on the 20th. Mercury is at greatest western elongation (20#176) on the 28th. Mercury sets at 6:38 p.m. on the 1st. On the 11th, Mercury will rise with the Sun. After Mercury transits the Sun, Mercury will return to the morning sky, rising before the Sun but will be lost in the early morning twilight glow until the last week of the month. Mercury rises at 5:19 a.m. by months end. Look for Mercury low to the southwest about 30 minutes after sunset during the first few days of November, then during the last week of the month before sunrise. Mercury is in the constellation of Libra this month shining at magnitude -0.6 on the 30th.

Mercury Transit Animation


Sets at 6:58 p.m. on the 1st and about 6:24 p.m. by month's end. Look for Venus soon after sunset to the southwest throughout the month, though it doesn't get much higher than 5° above the horizon making it difficult to spot. Venus is in conjunction with Jupiter on the 24th. Watch Venus and Jupiter appear to get closer each day until then. Venus moves from the constellation of Scorpius into Sagittarius shining at magnitude -3.8 on the 15th.

Earth Daylight Saving Time ends for most of the U.S. at 2 a.m. on the 3rd.

Rises at 5:45 a.m. on the 1st and about 4:26 a.m. by month's end. Mars continues to rise earlier making is easier to view in the morning sky before dawn. Look to the east about an hour before sunrise anytime after the 8th of the month when it will be high enough above the horizon to spot. Mars moves from the constellation of Virgo into Libra shining at magnitude 1.8.


Sets at 8:27 p.m. on the 1st and about 5:56 p.m. by month's end. Watch Jupiter descend towards the western horizon as Venus appears to rise to meet it. Jupiter and Venus are in conjunction on the 24th. Jupiter will continue its descent as Venus continues its rise after conjunction. Look for Jupiter low in the west soon after the skies darken after sunset. Jupiter moves from the constellation of Ophiuchus into Sagittarius shining at magnitude -1.9.


Sets at 10:05 p.m. on the 1st and about 7:20 p.m. by month's end. Look to the south-southwest about an hour after sunset to spot Saturn. Saturn is in the constellation of Sagittarius shining at magnitude 0.6.


Rises at 5:39 p.m. on the 1st and about 2:38 p.m. by month's end. Uranus still remains near its best and brightest following opposition in late October. By the time the Sun sets and the skies darken, Uranus is at least 20° above the eastern horizon. By late November, Uranus is highest in the south around 9:30 p.m. local time. Uranus is in the constellation of Aries shining at magnitude 5.7.


Sets at 3:10 a.m. on the 1st and about 12:11 a.m. by month's end. Neptune is stationary on the 27th. Look for Neptune to the south around 8:30 p.m. local time about halfway to the zenith. Neptune is in the constellation of Aquarius shining at magnitude 7.9.

Dwarf Planets


Sets at 8:20 p.m. on the 1st and about 6:09 p.m. by month's end. Ceres sets just a few minutes after Jupiter all month. However, Ceres is much dimmer compared to Jupiter and will be extremely difficult to spot. Ceres moves from the constellation of Ophiuchus into Sagittarius this month shining at magnitude 9.2.


Sets at 10:27 p.m. on the 1st and about 7:32 p.m. by month's end. Pluto still trails Saturn by less than 20 minutes all month long, however, this will not aid much in spotting this elusive planet as it is now much closer to the horizon and possibly lost in the evening twilight glow of sunset. Pluto is in the constellation of Sagittarius shining at magnitude 14.3.

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.

    This year, the waning gibbous Moon will interfere with all but the brighter meteors from this 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.

  • Comets

  • Comet PANSTARRS (C/2017 T2) should peak around 9th or 10th magnitude this month. Hopefully, by next spring, it will brighten enough to see with binoculars, but for now, you will need a 4-inch telescope or larger and very dark skies to see Comet PANSTARRS passing through the constellation of Auriga.

  • For information, orbital elements and ephemerides on observable comets, visit the Observable Comets page from the Harvard-Smithsonian Center for Astrophysics.

    For more information about Comets, visit Gary Kronk's webpage.

  • Eclipses

    Solar Eclipses

  • No solar eclipse activity this month.

    Lunar Eclipses

    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 - October 2, 2019
    An India-Pakistan nuclear war could kill millions, threaten global starvation

    Full Article & Images

    "A nuclear war between India and Pakistan could, over the span of less than a week, kill 50-125 million people--more than the death toll during all six years of World War II, according to new research.

    A new study conducted by researchers from CU Boulder and Rutgers University examines how such a hypothetical future conflict would have consequences that could ripple across the globe. Today, India and Pakistan each have about 150 nuclear warheads at their disposal, and that number is expected to climb to more than 200 by 2025.

    The picture is grim. That level of warfare wouldn’t just kill millions of people locally, said LASP atmospheric scientist Brian Toon, who led the research published today in the journal Science Advances. It might also plunge the entire planet into a severe cold spell, possibly with temperatures not seen since the last Ice Age."

    Visit LASP and MAVEN for more information.

    HiRISE Spots Curiosity Rover at Mars' 'Woodland Bay'

    Full Article & Image

    "A dramatic Martian landscape can be seen in a new image taken from space, showing NASA's Curiosity rover examining a location called "Woodland Bay." It's just one of many stops the rover has made in an area referred to as the "clay-bearing unit" on the side of Mount Sharp, a 3-mile-tall (5-kilometer-tall) mountain inside of Gale Crater."

    Mars Odyssey Orbiter - August 23, 2019
    What's Mars Solar Conjunction, and Why Does It Matter?

    Full Article and Images

    "The daily chatter between antennas here on Earth and those on NASA spacecraft at Mars is about to get much quieter for a few weeks.

    That's because Mars and Earth will be on opposite sides of the Sun, a period known as Mars solar conjunction. The Sun expels hot, ionized gas from its corona, which extends far into space. During solar conjunction, this gas can interfere with radio signals when engineers try to communicate with spacecraft at Mars, corrupting commands and resulting in unexpected behavior from our deep space explorers."
