Detailed explanation-1: -At the end of this first stage, the solar system contained millions of planetesimals-objects the size of small moons, having gravitational fields just strong enough to affect their neighbors.
Detailed explanation-2: -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-3: -According to this theory, the Sun and all the planets of our Solar System began as a giant cloud of molecular gas and dust.
Detailed explanation-4: -Planet-forming, or protoplanetary, discs are the precursors to planets. Astronomers speculate that the disc circling OTS 44 has enough mass to make a small gas giant planet and a few Earth-sized, rocky ones.
Detailed explanation-5: -The Sun accounts for 99.8% of all the mass in the solar system, with more than 1, 000 times the mass of the next largest solar system body, the planet Jupiter.
