What is the latest frequency of space mobile constellation _ What is the latest frequency of space mobile constellation?

The space mobile constellation has the latest frequency.

At the same time in different nights, the positions of constellations in the sky will gradually move from east to west with the passage of time.

The earth rotates every night, and the stars slide from side to side at night. The earth revolves around the sun, so the constellations in the night sky have ever-changing scenery. At the same time, the stars can only be seen at night with their backs to the sun.

The celestial bodies in the universe are constantly moving. The earth rotates once every 24 hours and revolves around the sun once every 365 days. The sun is also moving, leading the members of the entire solar system to move rapidly in the Milky Way at a speed of about 240 kilometers per second.

Extended data:

All celestial bodies in the universe, whether planets or stars, are moving at high speed. For example, Polaris is located in the north of the sky and can guide us at night. The current Polaris is called Gou Chenyi, which is about 434 light years away from the Earth.

Now Gou Chen-yi is just above the earth's rotation axis, so we look like due north. However, after 12000, Vega will replace the new Polaris.
