Detailed explanation-1: -Our solar system consists of our star, the Sun, and everything bound to it by gravity – the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune; dwarf planets such as Pluto; dozens of moons; and millions of asteroids, comets, and meteoroids.
Detailed explanation-2: -The Sun is the only star in our solar system. It is the center of our solar system, and its gravity holds the solar system together. Everything in our solar system revolves around it – the planets, asteroids, comets, and tiny bits of space debris.
Detailed explanation-3: -Correct answer: Stars, planets, moons, and other objects in space orbit around each other due to dark matter. Explanation: Stars, planets, moons, and other objects in space orbit around each other due to gravity.
Detailed explanation-4: -Each star orbits its galaxy’s center and has a slight random motion on top of this. Each star does not careen randomly about like a drunkard. Rather, each star travels on a smooth, nearly-straight trajectory as dictated by its own momentum and the local gravitational field.
