What holds the planets in their orbits around the sun?
A
gravity
B
speed
C
string
D
air currents
Explanation: 

Detailed explanation-1: -Gravity is what holds the planets in orbit around the sun and what keeps the moon in orbit around Earth. The gravitational pull of the moon pulls the seas towards it, causing the ocean tides. Gravity creates stars and planets by pulling together the material from which they are made.

Detailed explanation-2: -Because the Sun is the largest, most massive object in our solar system, it also has the strongest gravitational force in our solar system. It pulls every one of the planets (and everything else) toward its center of mass.

Detailed explanation-3: -Since the sun has a greater mass, it has a greater gravitational force that attracts the bodies with lesser masses. In addition, gravity produces the centripetal force, which is the inward pull that prevents the planets from moving out of their orbits.
