Question

what occurs when the velocity of earth is doubled?

Answer 1

As indicated by Newton's laws, if the orbit velocity is expanded, and there are no other outer powers following up on the earth other than the gravity itself, the radius of orbit needs to be increased to adjust the diffusive force and the gravity. Henceforth, this is normally unrealistic until the point that some extraterrestrial does this analysis on our nearby planetary group.

In the event that the orbital velocity of earth copies then the mean solar day of the earth will diminish to the half and the solar year will likewise decrease to the half comparably the direct velocity of the earth will likewise lessen.
