One of the methods used widely to calculate the distance of nearby or closer objects in astronomy is Parallax. The distance of the stars are usually expressed in light years but the unit of distance is parsec or parallax second.
1 Parsec = 3.26 light years
Astronomers are not able to measure the parallax of a star that is a million light years away because the star is too far and the distance with which the start appears to move is too less to be calculated accurately.
I believe the correct answer will be A
Just post them in like 2 or 3 post like maybe 15 or 25 questions per post, if anyone knows the answer, then they will just answer it below!
