The centripetal acceleration is therefore worth: 141.26 / 9.81 = 14 times the acceleration of gravity
Explications:
Hello,
More or less, we can consider the orbital trajectory of the Earth as circular.
Under these conditions, the centripetal acceleration of the movement of the Earth around the Sun can, in an approximate way, correspond to: v² / r.
With: v = 30 km / s and r = 6,371 km; that is: a = (30,000) ² / 6,371,000 = 141.26.
