When is Jupiter’s Closest Approach to Earth in December?
Jupiter’s closest approach to Earth in December occurs every 13 months, during its opposition to the Sun. In 2022, Jupiter will reach opposition on December 27th, when it will be approximately 390 million miles (628 million kilometers) from Earth. This close approach provides a great opportunity to observe the gas giant in detail using binoculars or telescopes. Jupiter’s moons, including the famous Great Red Spot, will also be visible.
December Meteor Showers
December is a peak season for meteor showers, offering observers several opportunities to witness celestial displays. Here are the notable meteor showers of December:
- Geminids: Active from December 4-17, the Geminids are one of the most prolific meteor showers of the year, producing up to 120 meteors per hour at their peak. They originate from the debris trail of the asteroid 3200 Phaethon.
- Ursids: The Ursids take place from December 17-26, reaching their maximum activity on December 22. They are a smaller shower, producing around 10 meteors per hour. They originate from the debris trail of comet C/1983 N1 (Sugano-Saigusa-Fujikawa).
- Quadrantids: Occurring from December 28-January 12, the Quadrantids are an annual meteor shower that peaks on January 3-4. They are moderately active, producing up to 120 meteors per hour at their peak. They are associated with the extinct comet 2003 EH1.
These meteor showers provide excellent opportunities for stargazers to enjoy the beauty and wonder of the night sky. Favorable viewing conditions include clear, dark skies and a location away from light pollution.
Meteor Showers in December Associated with Jupiter
The Geminid and Ursid meteor showers occur in December and are both associated with the planet Jupiter. The Geminid meteor shower is active from December 7-17, with peak activity on December 13/14. It produces slow, medium-bright meteors that are often green or blue. The parent body of the Geminids is an asteroid named 3200 Phaethon.
The Ursid meteor shower is active from December 17-26, with peak activity on December 22. It produces slow, faint meteors that are often white or yellow. The parent body of the Ursids is a comet named C/1983 N1 (Ikeya-Zhang).
Stargazing Jupiter in December
Jupiter, the largest planet in our solar system, will be visible in December at its brightest and largest.
- Best viewing time: Jupiter will be at opposition on December 21, meaning it will be opposite the Sun in the sky and visible all night long.
- Location: Jupiter will be located in the constellation Pisces, rising in the east and setting in the west.
- Visibility: Jupiter will be easily visible to the naked eye as a bright star-like object. Binoculars or a telescope will further enhance the view, revealing its bands, moons, and Great Red Spot.
- Other planets: Mars, Saturn, and Venus will also be visible in December, providing an opportunity for multiple planet-watching sessions.
Best Time to See Jupiter in December
Jupiter, the solar system’s largest planet, is at its best for observation in December. The planet appears high in the night sky and is visible all night long. Here are the optimal times to catch a glimpse of Jupiter:
- Peak Viewing: December 17-18, 2023
- Ideal Hours: Midnight to 4 am local time
- Direction: Look towards the eastern sky
- Telescope Recommendation: A telescope with an aperture of at least 4 inches will reveal Jupiter’s bands, moons, and Great Red Spot.
Meteor Shower Associated with Jupiter in December
In December, the Geminid meteor shower is active, which is associated with the asteroid 3200 Phaethon, not Jupiter. This meteor shower is known for its high frequency, with up to 120 meteors visible per hour at its peak. The Geminids appear to radiate from the constellation Gemini, hence their name. The peak of the shower typically occurs around December 14th each year.
Observing Jupiter’s Moons in December
In December, Jupiter’s four Galilean moons (Io, Europa, Ganymede, and Callisto) offer prime observing opportunities. Here’s what to expect:
- December 1: Io will transit (cross in front of) Jupiter’s disc at 07:18 UTC, followed by Callisto at 14:32 UTC.
- December 2: Io will transit again at 01:16 UTC, and Ganymede will occult (pass behind) Jupiter at 21:17 UTC.
- December 5: Europa will transit at 21:59 UTC.
- December 6: Io will cast its shadow onto Jupiter’s disc at 02:37 UTC.
- December 7: Io will transit a third time at 23:55 UTC.
- December 8: Callisto will transit at 09:37 UTC.
- December 9: Io will cast its shadow again at 05:16 UTC.
- December 10: Ganymede will transit at 07:36 UTC.
Jupiter’s Visibility in the Night Sky in December
Jupiter will be highly visible in the night sky throughout December 2023. It will be at its highest point in the sky around midnight, making it easy to spot with the naked eye. Jupiter will appear as a bright, yellowish-white star, and will be located in the constellation of Taurus. Through a telescope, observers will be able to see Jupiter’s four largest moons, as well as its banded cloud formations and swirling atmosphere.
