The Seven Sisters are seven stars located more than 400 light-years away in the Taurus constellation and they can be seen here with Venus and another constellation, Orion. Why do these stars seem so small compared to our Sun, also a star?
A) Our Sun is much larger than any of the Seven Sisters.
B) Our Sun is much closer to Earth than the Seven Sisters.
C) The Seven Sisters are ancient stars; the Sun is a young star.
D) Stars found in constellations are much older and smaller than any other

Option B

Explanation:

The seven stars are bigger in size as compared to the size of the sun. Also, these stars are more luminous as compared to sun. However, these stars appear small in size in comparison to sun because of their distance from earth. The larger is the distance, the dimmer is the star. Sun is at a distance of 0.0000158 Light years from Earth while the nearest star of the seven sister i.e Alpha Centauri is 4.37 light years away.
