Detailed explanation-1: -The Milky Way contains between 100 and 400 billion stars and at least that many planets.
Detailed explanation-2: -“Earth is in the Milky Way galaxy. It’s home to over 200 billion stars with ours being the sun.” Not only is the Milky Way a huge accumulation of stars, but it holds planets, asteroids, meteors, comets and other solar remnants. Most stars are at the center of the galaxy with few at the outer edges.
Detailed explanation-3: -Our most detailed observations of the distant Universe, from the Hubble eXtreme Deep Field, gave us an estimate of 170 billion galaxies. A theoretical calculation from a few years ago-the first to account for galaxies too small, faint, and distant to be seen-put the estimate far higher: at 2 trillion.
