Orbital Energy with Different Masses


Two planets, Planet 'A' and Planet 'B' are orbiting the same star. Planet 'A' has one third the mass of planet 'B', and both orbit in perfect circular paths. However, Planet 'B' has twice the orbital radius of Planet 'A.'

Which planet has more total orbital mechanical energy?

Planet 'A' has

total orbital mechanical energy than Planet 'B'
