Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The orbital motions of the objects in the solar system are the direct result of which of the following features of the Sun?
A
Its chemical composition
B
Its gravitational pull
C
Its brightness
D
Its magnetic field
Explanation: 

Detailed explanation-1: -The Sun’s gravity pulls the planets in orbit around it, and some planets pull moons in orbit around them. Even spacecraft are in motion through the solar system, either in orbit around the Earth or Moon, or traveling to further worlds, because of gravitational forces.

Detailed explanation-2: -The sun is at the center of the solar system, with other objects orbiting around it. The force of gravity holds the solar system together and governs the movement of the objects within the solar system.

Detailed explanation-3: -Planetary motions around the sun can be predicted using Kepler’s three empirical laws, which can be explained based on Newton’s theory of gravity. These orbits may also change somewhat due to the gravitational effects from, or collisions with, other bodies.

Detailed explanation-4: -The Sun actually oscillates due to the gravitational effect of Jupiter’s mass. The oscillation is however very small. To further complicate matters, planetary orbits are in fact not circular.
