Which force helps keep Earth in orbit?

Answer
A
Earth’s gravity
B
the moon’s inertia
C
the Sun’s gravity
D
the Sun’s inertia

Explanation

The Sun’s gravity pulls Earth toward the Sun and provides the force that keeps Earth moving in its orbit. Earth’s forward motion prevents it from falling directly into the Sun, while the Sun’s gravity continually bends its path. The correct choice is the Sun’s gravity.
