Question

A heavenly body is 6 light minutes away from the Earth. Its distance in Km is ____________

Answer 1

SOLUTION-;

• a light-minute is 60 light-seconds, and the average distance between Earth and the Sun is 8.317 light-minutes.

• 8*60) sec * (3*10^8) m/sec
• =(1.44*10^11)/10^3 km
• =1.44*10^8 km

• ∵ 1' = 2.91 × 10⁻⁴ radians.  
• ∴ 2' = 5.8 × 10⁻⁴ radians.  
• Hence, Parallax angle (θ) = 5.8 × 10⁻⁴ rad
• Now, Using the Formula,  
• θ = Basis/Distance
• ∴ Distance = (6.4 × 10⁶)/(5.8 × 10⁻⁴) rad
•   = 1.10 × 10¹⁰ m.  
•   = 1.1 × 10⁷ km.
