Answer 2

Answer: Orbital speed of an astronomical body or object is the speed at which it orbits around a object.

v = the orbital velocity of an object (m/s)

G = the universal gravitational constant, G = 6.673x10(-11) N∙m2/kg2

Me= the mass of the Earth (5.98 x 1024 kg)  

r = the distance from the object to the center of the Earth

V=square root gm which is a bit lower  and upon r
