I've been working on this for five hours and I am on the verge of despair!
Can anybody help with this question? All I need is an equation!
There are two extrasolar planets (X and Y) that are orbiting two stars with the same mass as our Sun (1.9891 × 10^30 kg), i.e. the planets are in two separate solar systems. For the purposes of this question, you should assume that there are no other planets in either system and that both stars are at a distance of around 1000 pc from Earth.
Properties of extrasolar planets X and Y:
Planet Mass/ME *Note: ME is the mass of the Earth (5.974 × 10^24 kg)*
Planet X = 12
Planet Y = 150
Radius of star’s orbit from centre of mass of the system/km
Planet X = 2×10^4
Planet Y = 2×10^3
Orientation of the system
Planet X = face-on
Planet Y = edge-on
Question:
Determine the orbital radius for each extrasolar planet X and Y. You should state your answer in astronomical units (AU).
Can anybody provide an equation that I can use to figure this out?
Many thanks
