Question

When the planet Jupiter is at a distance of 824.7 million kilometers from the Earth, Its angular diameter is measured to be 35.72'' of arc. Calculate the diameter of Jupiter.

Answer 1

D = 824.7 million km

θ = 35.72¹¹

b = Dθ

=> b = 824.7 v 10⁶ km × 35.72¹¹

824.7 × 10⁶ km × (35.72/3600) × (π/180) km

= 1.429 × 10⁵ km
