Nicolaus Copernicus observes a lunar eclipse on November 5, 1500. Wolfgang Schuler independently discovers Tycho’s Supernova on November 6, 1572. Cornelius Gemma independently discovers Tycho’s Supernova on November 9, 1572. Tycho Brahe observes Tycho’s Supernova on November 11, 1572. SN 1604 (Kepler’s Supernova) becomes visible to the unaided eye on October 9, 1604. Nicolas-Claude Fabri de Peiresc makes the first telescopic observations of M42 (the Orion Nebula) on November 26, 1610. Jan de Munck discovers Comet C/1743 X1 (the Great Comet of 1744) on November 29, 1743. Captain James Cook observes a transit of Mercury from New Zealand on November 9, 1769. William Herschel discovers the ring galaxy NGC 922 on November 17, 1784. E.E. Barnard discovers the emission nebula NGC 281 (the Pacman Nebula) on November 16, 1881. The first photograph of a meteor was taken on November 26, 1885. The minor planet/comet 2060 Chiron or 95P/Chiron was discovered by Charles Kowal on November 1, 1977.

The peaks of the Southern and Northern Taurid meteor showers take place on November 5th and November 12th respectively. These streams form part of the complex associated with Comet 2P/Encke. The Leonid meteor shower occurs on the night of November 17th/18th. Leonid meteors are debris from the periodic comet 55P/Tempel-Tuttle, which last reached perihelion in 1998. Due to their high speed (71 kilometers or 44 miles per second), the fastest of any meteor shower, the Leonids produce more fireballs than most showers. Browse ... or-shower/ for information on the 2021 Leonids. See ... s-in-2021/ for information on 2020’s better meteor showers.

The Sun is located in Libra on November 1st at 0:00 UT. It moves into Scorpius on November 23rd and Ophiuchus on November 30th.

Brightness, apparent size, illumination, distance from the Earth in astronomical units, and location data for the planets and Pluto on November 1st: Mercury (magnitude -0.8, 5.8", 79% illuminated, 1.15 a.u., Virgo), Venus (magnitude -4.6, 25.6", 48% illuminated, 0.65 a.u., Ophiuchus), Mars (magnitude +1.7, 3.6", 100% illuminated, 2.59 a.u., Virgo), Jupiter (magnitude -2.5, 42.2", 99% illuminated, 4.68 a.u., Capricornus), Saturn (magnitude +0.6, 16.8", 100% illuminated, 9.91a.u., Capricornus), Uranus (magnitude +5.7, 3.8", 100% illuminated, 18.76 a.u. on November 16th, Aries), Neptune (magnitude +7.9, 2.3", 100% illuminated, 29.47 a.u. on November 16th, Aquarius), and Pluto (magnitude +14.3, 0.1", 100% illuminated, 34.63 a.u. on November 16th, Sagittarius).

During the evening, Venus is in the southwest, Jupiter and Saturn in the south, Uranus is in the east, and Neptune in the southeast. Jupiter and Uranus lie in the southwest and Neptune in the west at midnight. Mercury and Mars are located in the east and Uranus in the west the morning sky.

Mercury is briefly visible in the eastern morning sky. The waning crescent Moon occults Mercury from Bermuda, the northeastern United States, and most of Canada on the afternoon of November 3rd. Mercury and the Moon will be only 15 degrees from the Sun so observing this event with a telescope must be done with extreme caution. Mercury is 1.1 degrees north of Mars on November 10th. The speediest planet is in superior conjunction with the Sun on November 29th.

Venus increases in brightness from magnitude -4.6 to magnitude -4.9 and 7.6 arc seconds in angular size during November. It decreases in illumination from 48% to 30%. A 3-day-old waxing crescent Moon passes 1.1 degrees north of Venus on the evening of November 7th in the Americas, with an occultation occurring in some parts of Asia.

Mars is lost in the glare of the Sun until very late in November, when it reappears in the morning sky.

Jupiter dims slightly from magnitude -2.5 to magnitude -2.3 and shrinks in angular size from 42.2 to 38.5 arc seconds. The gas giant remains approximately 16 degrees east of Saturn for the entire month. Jupiter is located 1.9 degrees northwest of the third-magnitude star Deneb Algedi on November 1st and 2.2 degrees northeast of the star on November 30th. The First Quarter Moon passes four degrees to the south of Jupiter on November 11th. Double Galilean satellite shadow transits take place on November 2nd and November 23rd. Information on Great Red Spot transit times and Galilean satellite events is available on pages 50 and 51 of the November 2021 issue of Sky & Telescope and online at ... ing-tools/ and

At midmonth, Saturn's globe subtends 17 arc seconds. Its rings span 38 arc seconds and are inclined by 17 degrees, displaying the planet's northern hemisphere. The waxing crescent Moon passes four degrees south of Saturn on November 10th. Eighth-magnitude Titan is north of Saturn on November 6th and November 22nd and south of the planet on November 14th and November 30th. Iapetus is at inferior on November 17th and lies within one arc minute of Saturn from November 17th to November 19th. The peculiar satellite brightens to approximately eleventh magnitude by the middle of the month. For information on the positions of Saturn’s major satellites, browse ... hing-tools

On November 1st, Uranus is located 0.8 degrees north of Omicron Arietis (magnitude +5.7). The ice giant shines at the same magnitude when it reaches opposition on November 4th and is visible for the entire night. At that time, Uranus lies 2.6 light hours from the Earth. As Phil Harrington describes in his Cloudy Nights article appearing at ... anus-r3263, Uranus can be seen without optical aid from a dark site. A nearly Full Moon passes less than two degrees southeast of Uranus on November 17th. Finder charts are available at and and ... nd-uranus/

Neptune is located a bit more than three degrees northeast of the fourth-magnitude star Phi Aquarii in eastern Aquarius on November 1st. The waxing gibbous Moon passes five degrees southwest of Neptune on November 13th. Browse and ... 2021_1.pdf and ... nd-uranus/ for finder charts.

Finder charts for the dwarf planet Pluto can be found at pages 48 and 49 of the July 2021 issue of Sky & Telescope, on page 243 of the RASC Observer’s Handbook 2021, and online at

Comet 67P/Churyumov-Gerasimenko travels eastward through Gemini and into Cancer this month. The periodic comet may brighten from ninth to eighth magnitude during November. It passes about two degrees south of Pollux on November 7th and some seven degrees north of the open cluster M44 on November 29th. Comet C/2021 A1 (Leonard) is located in in Ursa Major and shines at tenth magnitude as November begins. This comet is predicted to brighten rapidly, moving into Coma Berenices by the end of the month. For additional information on comets visible this month, browse and and

The dwarf planet/asteroid 1 Ceres travels northwestward through Melotte 25 (the Hyades) in Taurus this month. Ceres passes just south of Aldebaran on November 2nd and reaches opposition, shining at magnitude +7.2, in Taurus on November 23rd. Asteroid 521 Brixia (magnitude +10.4) is at opposition in Taurus on November 29th. Data on asteroid occultations taking place this month is available at and

Two stars with exoplanetary systems, Upsilon Andromedae (magnitude +4.1) and 51 Andromedae (magnitude +5.5), can be seen this month without optical aid.

The famous eclipsing variable star Algol (Beta Persei) is at a minimum, decreasing in brightness from magnitude +2.1 to magnitude +3.4, on November 3rd, 6th, 9th, 12th, 15th, 18th, 20th, 23rd, 26th, and 29th. Consult ... ing-tools/ and page 50 of the November 2021 issue of Sky & Telescope for the times of the eclipses. Algol is at minimum brightness for observers in North America for about two hours centered at 6:36 p.m. EST on November 14th and at 9:25 p.m. EST on November 17th. The chance of seeing Algol at least one magnitude fainter than normal on a random night is about 1 in 30. For more on Algol, see and
