The formula v2 = GStartFraction m Subscript central Baseline over r EndFraction is very useful for astronomers because it does not require them to know T. What does T stand for?

orbital period
tangential speed
satellite radius

orbital period

(T is the orbital period — the time for one complete orbit. Using v = 2πr/T and equating centripetal and gravitational forces lets you eliminate T and get v^2 = GM/r.)
