Stars rise approximately 4 minutes earlier each day, leading to a slight change in their rising time. A star that rises at 8:30 p.m. tonight will rise very close to 24 hours from now, approximately 2 months from now.


Explanation:

Sidereal Time and Solar Time

The time from star-rise to star-rise, or an exact rotation of the earth, is called a sidereal day. Its exact length is 23 h. 56 m. 4.09 s. The time between two successive passages of the sun over a given meridian, or from noon by the sun until the next noon by the sun, is called a solar day.

Since stars make a complete circle in the sky in 23 hours and 56 minutes, a star that rises at a specific time will rise approximately 4 minutes earlier each day. Hence, a star that rises at 8:30 p.m. tonight will rise very close to 24 hours from now approximately 2 months from now.
