Question

What are the steps of solar system formation in order

Answer 1

Sun, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.

Answer 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.
