Constellation 1838 _ How big is the constellation 38mm?

How big is the Big Dipper? How far are they from the earth?

The Big Dipper is located in Ursa Major. Under good observation conditions, the Big Dipper can be found in the night sky in the northern hemisphere almost every day. Seven bright stars form a unique spoon shape, which is easy to identify. In places with good observation conditions, there are more than 2,000 stars visible to the naked eye in the night sky. There are more than 7,000 stars visible to the naked eye on the whole earth, including the Big Dipper in the northern sky. Water, gold, fire, wood and earth are the planets in our solar system. They revolve around the sun like the earth.

As the only known star in the solar system, the mass of the sun accounts for 99.86% of the total mass of the solar system, and the strong gravity determines the motion of the planets. Except for five planets, all the stars in the night sky are actually stars, and the Big Dipper is also a star. Since it is a star, it can emit light and heat through nuclear fusion. Not only that, most stars are surrounded by planets, just like our sun. Yao is a very young star with a history of only 10 million years, while our sun has a history of 4.6 billion years.

The star is 103.9 light-years away from the earth, its mass is 6. 1 times that of the sun and its brightness is 594 times that of the sun. If the sun is replaced by Kony light, the earth will be burned and the livable area will move 3.6 billion kilometers, which is roughly outside the orbit of Uranus. Astronomers found that Kaiyang is not a simple binary system, but a rare six-star system. There is a smaller star nearby, forming a binary star system. There are three stars near Kaiyang, forming a quadrilateral system. These six stars combine with each other under the action of gravity to form a larger star system.
