Question

the Parallactic angle Subtended by a distant star is 0.76 on earth's orbital diameter (1.5×10¹¹ m).Calculate the distance of the star from the earth​

Answer 1

Answer:

Explanation:

distance of star from earth = D

parallax angle= 0.76 rad

distance between two observation points = d= 1.5 x 10¹¹m

so, as

D = d/ Ф

D= 1.5 x 10¹¹/ 0.76

= 1.97 x 10¹¹m
