Determine the diameter of a star in kilometers, with an apparent angular diameter of 0.005 “and a parallax of 0.035” if it is perpendicular to the plane of the earth’s orbit.
The distance to this star will be = 150,000,000 ∙ ctg 0.035 “km. Then its size = 150,000,000 ∙ ctg 0.035” ∙ tan 0.005 “= 2.1 ∙ 10 ^ 7 km
