1) where ? {displaystyle alpha } is the gravitational parameter and is equal to ? = G (m 1 + m 2) {displaystyle alpha =G(m_{1}+m_{2})} In many applications, a third simplifying assumption can be made: 3. When compared to the central body, the mass of the orbiting body is insignificant. Mathematically, m 1 >> m 2, so ? = G (m 1 + m 2) ? Gm 1. This assumption is not necessary to solve …
An observer measures the spectrum of two planets emitting as blackbodies, one with a temperature of T1=300K, similar to the Earth’s, and the second with a temperature of T2=800K, similar to Venus’.
