What constellation is 1 month 16?

1. 16 is Capricorn, Capricorn 65438+February 22nd-65438+1October 19.

Capricorn is also called Capricorn. There are 65 stars brighter than 6, but there are 3-4 main stars, which is the second faint constellation. Unlike most constellations, the brightest star in Capricorn is not its alpha star, but its delta star, which is called Wall Array 4 in Chinese and slightly brighter than 3.

Every year at midnight on August 8, Capricorn reaches the zenith. In the southern night sky in August and September, the weather is fine and the light pollution is weak. Observers in the middle and low latitudes in the northern hemisphere can see the dark Capricorn on the east side of Sagittarius.

Extending from Vega to Altair about 1 time, you can see two third-class stars, which are the heads of Capricorn. Then connect the scattered dark stars from here to the east to form a roughly inverted triangle, which is Capricorn.

Extended data:

Capricorn is also related to a story in astronomical history. Astronomers observed that Uranus was disturbed in its orbit around the sun. After calculation and observation, Neptune, the eighth planet in the solar system, was discovered in A.D. 1846, so Neptune is called "the planet found on the tip of a pen". Neptune was in Capricorn.

Capricorn has very few deep space objects suitable for astronomy enthusiasts, except M30 in Messier's list of objects. This is a globular cluster, 24,000 light years away from the Earth, with a magnitude of about 7 and an apparent diameter of 12 minute.

M30 can be detected with 50 mm binoculars. When observed at high magnification in an astronomical telescope with a diameter of more than 6 inches (15 cm), it can decompose some star clusters into stars.
