The orbital speed of the object is the speed at which it orbits around the barycenter of a system which is usually around a massive body. Around the sun orbital speed of the earth is 108,000 km/h.
The orbital speed formula is provided by,
G = gravitational constant
M = mass of the planet
r = radius.
The mass of an object is given as 8.35×1022 Kg and the radius is given as 2.7×106m. Find the orbital speed.
M = 8.35×1022kg
R = 2.7×106m
G = 6.673×10-11m3/kgs2
Orbital speed equation is given by,
vorbit = √GM / R
vorbit = √6.673×10−11 ×8.35×1022 / 2.7×106
vorbit= 20.636 x 106 m/s.
