Question

What would happen if
a. the Earth slows down its movement around the Sun?​

Answer 1

Explanation:

if the Earth's orbital velocity slowed down, then it fall into a lower orbit to compensate. ... But even if the Earth slowed gently to a stop, it would still be a horrible mess. Without the outward centripetal force to counteract the inward pull of gravity, the Earth would begin falling towards the sun.
