Many of the exoplanets discovered thus far are in orbits near their stars.This means they are probably:
A) spinning rapidly to conserve angular momentum.
B) doomed to spiral into their stars.
C) recently formed.
D) in synchronous orbits.

Question

Quizplus · Accepted Answer

Exoplanets in orbits near their stars are often tidally locked, which means they are in synchronous orbits where one side of the planet always faces the star. This is due to the gravitational forces between the planet and its star, which over time slows down the planet's rotation until it becomes locked into a synchronous orbit.
