An overview of the major celestial bodies of the Solar System
Sun: Runs in Sagittarius on the 1st-19th and in Capricorn on the 20th-31st. A little chill on January 5 and a big chill on January 20.
Mercury: A late star that travels in Sagittarius on the 1st, in Capricorn on the 2nd-14th, retrograde in Capricorn on the 15th-25th, and retrograde in Sagittarius on the 26th-31st. Approaching the Sun from mid-to-late onwards, the observation conditions are not good. At the end of the month, the daily distance angle is about 16 °, the apparent brightness is about 1.4, etc., and the observation conditions are improving.
Venus: Retrograde in Sagittarius, turning to anterograde after staying on the 29th. The first half of the moon is close to the sun and is not easy to observe. After 15 days, the sun angle expands to 12°, appearing in low southeastern altitudes before sunrise. At the end of the month, the daily distance angle expands to 30 °, the horizon height is about 25 ° at sunrise, the brightness is -4.8, etc., and the observation conditions are getting better and better.
Mars: Anterograde in Ophiuchus from 1 to 19, and enter Sagittarius from the 20th. It rises from the southeast around 5 o'clock. At the end of the month, it is about 36° from the sun and has an apparent brightness of about 1.4 degrees.
Jupiter: Advantag. At the end of the month, the distance angle is reduced to 25°, and it falls at about 19:30, and the apparent brightness is about -2.
Saturn: Anterograde in Capricorn. The first day of the month is about 31 ° from the angle, the brightness is about 0.7, and then it quickly approaches the sun, and the end of the month is basically invisible.
Uranus: Retrograde in Aries on the 1st-19th, change to anterograde after the sun stay. The drop-off time is advanced from about 2:30 to about 0:30. The sun angle is reduced to about 90 °, and the apparent brightness is about 5.7, which is conducive to observation.
Neptune: Going down in Aquarius. The drop-off time was moved from around 22:30 to around 20:30. The sun angle is reduced to 40°, and the apparent brightness is about 8.0 magnitude.

MUST SEE
On January 3, Comet Leonard crossed perihelion
Rare index ★★ ☆☆☆☆
Difficulty index ★★★★★
Referral index ★★★★★
Comet C/2021 A1 (Leonard), as the brightest comet in 2021, did not disappoint. At least it survived as expected and was observed by many domestic enthusiasts before and after reaching perigee. Unexpectedly, however, after the comet changed from a morning star to a dusk star, it suddenly exploded, reaching a brightness visible to the naked eye at one point. And as it gets closer to the sun, it also develops more and more beautifully. Because it happens to be during the Christmas period, this comet is even called "Christmas Comet" by many foreign netizens.
The good news is that it will always be in the southwest corner of the southern constellation (near the microscope seat, Azuru). The bad news is that for observations in the Northern Hemisphere, while there is still a chance to observe, the altitude is too low, too difficult, and there is only a 10-15 day opportunity to observe. Located in the southwest, at high altitudes, in dry air, there may still be opportunities.

January 4 The Hijlids meteor shower is extremely large
Rare index ★ ☆☆☆☆☆
Difficulty index ★ ☆☆☆☆☆
One of the three major meteor showers in the northern hemisphere, ZHR ~ 100, crescent moon - these three characteristics are in front of you, what reason is there to refuse? Of course, except for the cold, haha.
The quadrant constellation is an ancient constellation that is no longer in the 88 constellation sequence. The radiant point is located in the constellation of Shepherd. It will rise from the northeast around 0 o'clock, so it can be observed throughout the second half of the night, and the conditions are very good, and it is best to expect 3-4 am. It is recommended to focus on the Arctic, Zenith and Southeast Virgo-Raven lines.

January 4 Earth passes perihelion
Having to accept reality, the earth has turned around again! Have you grown up a bit?

January 7 Mercury East Distance
Difficulty index ★★★★ ☆
Recommended index ★★★ ☆☆
This is the first mercury distance this year, but the sun distance angle is only about 19 °, the horizon altitude at sunset is only 17 °, and the brightness is about -0.5. This means that by the time you can see Mercury, the horizon altitude is estimated to be only about 10°, so it is more difficult and not the best opportunity this year. However, if you want to become a stargazing expert, it is still worth the challenge.
