How did the planets and the moons come to be in our solar system?
Yes, one or more stars did go supernova, but no, the Sun did not grab any planets from another star. This is why man astronomers think the sun is a population II star. Its metallicity is too high (Ca content) for it to be a Population II star.The sun and all the bodies in out solar system were created from the same solar nebula and disc. All of the planets and the sun rotate in the same direction around the sun’s rotational axis. Thee planets, Venus, Uranus, and Pluto, have had one or more impacts with massive celestial bodies that tilted their rotational axes so that Venus and Uranus rotate in the retrograde direction around their rotational’gegographical axes. Asteroids that are grabbed by a massive planet’s gravity to become satellites often rotate around the planet in a retrograde direction. http://science.jrank.org/pages/6265/Sola…
