The Gemini meteor shower appears between 4 and 17 December each year. The meteor is generally lighter and has a medium speed of movement, which was the main target of the astronomical enthusiast. This year's Gemini meteor shower took place on December 14th, and the point of radiation rose from northeast to the afternoon, and the zenith hourly meteorological number was 120. "At this point, it's the first quarter of a month, the observation conditions are better in the middle of the night. attention to the cold and warmth when we look at it. "
In December, a comet can be seen with the naked eye – Vertanin's comet. Wang Yumin said this is a short-lived comet that lasts about 5.44 years around the sun.

Understand that it will pass near the orbital proximity on August 13, and the closest to Earth 16, about 10 million miles away from us, with light 3 and so on. Not far from the comets of the Taurus group. "This can be seen with the naked eye in places where the light pollution is light, which will be even better with the telescope, and this is the brightest comet of the year."

"Remember your position and direction of travel, and you can still see when the weather is nice after the sun goes out."
July 15 Mercury will travel to the West. At this point, Mercury is the star of the morning, and at sunset, is located in the southeast of the sky. At the western distance, the maximum angular distance between Mercury and Sun is 21 °, the ground level is about 17 °, and the brightness is about -0.5. Observation conditions are very good. Mars will go straight from Aquarius to Ribe this month. It is located in the southern sky at sunset at 3. and can be seen in the middle of the night.
