Hello all,
I need your help to win a bet here.
Here's the bet:
I say, that the Earth moves faster through space (higher velocity) than Mercury, because our Orbit over the Sun is a higher altitude.
For example, when you are in LEO ~150km, you need a positive prograde burn to increase your velocity to achieve a higher orbit. Is this not the same for planets?
He claims, that Mercury moves faster through space (higher velocity) than the Earth, because it requires more velocity to overcome the greater gravitational force of the Sun.
Who is right? I hope it's not him, or I'm out a pack of smokes. :rofl:
Cheers,
_O.K._
