Question

The sun appears to move ___ among the stars.

• A. Proxima Centauri
• B. North Star
• C. Dog Star
• D. Rigel

Answer 1

The correct option is A

Proxima Centauri

The earth requires $365\frac{1}{4}$ days for revolving once around the sun. A change in position at the rate of about $1^{\circ }$ per day takes place for the earth. Owing to this revolving motion of the earth around the sun, for an observer at the equator, the stars in the background of the sun appear to move westward by $1^{\circ }$. As a result, the sun would appear to move eastward among the stars. In this way, the trajectory along which the sun appears to move is the ecliptic.
