Gravity is responsible for which of the following characteristics of a galaxy?
A
The color of light it emits
B
Its location within the universe
C
The size of its largest stars
D
The motion of the objects within it
Explanation: 

Detailed explanation-1: -So, for astronomical objects, gravity is the only force which affects their motion. Gravity is an example of a force. Gravity causes every object that has mass to attract every other object that has mass with a gravitational force.

Detailed explanation-2: -Gravity causes the motions of planets, stars, and galaxies. It’s why the Moon orbits around the Earth, and the Earth orbits around the Sun, and the solar system orbits around the galaxy. It’s all because of gravity. Gravity is the reason stars and planets are spherical.

Detailed explanation-3: -Gravity is the long-range force that can pull entities with mass together over great distances to form galaxies, stars and planetary material. These objects are all the consequence of atoms and ions being first clustered into huge clouds of gas.

Detailed explanation-4: -Gravity is responsible for returning you to the Earth, and making an object fall. Without gravitational pull, objects would float off into space. Gravity exists everywhere. The Sun’s gravity impacts the entire solar system, which keeps the planets in their orbits.
