Detailed explanation-1: -Our solar system is made up of a star-the Sun-eight planets, 146 moons, a bunch of comets, asteroids and space rocks, ice, and several dwarf planets, such as Pluto.
Detailed explanation-2: -The Sun and the planets formed together, 4.6 billion years ago, from a cloud of gas and dust called the solar nebula. A shock wave from a nearby supernova explosion probably initiated the collapse of the solar nebula. The Sun formed in the center, and the planets formed in a thin disk orbiting around it.
Detailed explanation-3: -A comet nucleus is the solid core of a comet consisting of frozen molecules including water, carbon monoxide, carbon dioxide, methane and ammonia as well as other inorganic and organic molecules-dust. The nucleus of a comet is usually around 6 miles (10 kilometers) across or less (opens in new tab).
Detailed explanation-4: -1.) Hydrogen. Created during the hot Big Bang but depleted by stellar fusion, 70% of the Universe remains hydrogen. 2.) Helium. About 28% is helium, with 25% formed in the Big Bang and 3% from stellar fusion. 3.) Oxygen. 4.) Carbon. 5.) Neon. 6.) Nitrogen. 7.) Magnesium. 8.) Silicon. More items •25-May-2020
