The order of the planets in the solar system, starting nearby the sun and working outside is the following: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and then the possible Planet Nine.Ever given that the discovery of Pluto in 1930, kids grew up finding out that the solar system has nine planets. Related: The solar system: A guide to things orbiting our sunThe planets: The lots of worlds of our solar systemThe inner four planets closest to the sun– Mercury, Venus, Earth and Mars– are often called the “terrestrial worlds” since their surfaces are rocky. Below is a short overview of the 8 real planets in our solar system, moving from that closest to the sun to farthest from the sun: Mercury: The closest planet to the sunMercury is the closest planet to the sun. Find out more about Pluto: Planet Nine: A world search at solar systems edgeThe hypothesized Planet Nine is estimated to be about 10 times the mass of Earth (Image credit: ESO/Tom Ruen/nagualdesign) In 2016, researchers proposed the possible existence of a ninth world, for now, called “Planet Nine” or Planet X. The research is based on mathematical models and computer simulations using observations of 6 other smaller sized Kuiper Belt Objects with orbits that aligned in a comparable matter.A recent hypothesis proposed September 2019 on the pre-print server arXiv recommends Planet Nine might not be a planet at all.
