Today, scientists believe the Solar System began with a spinning gas and dust cloud. As more information comes in, some of our theories of the Solar System must change to suit the new evidence. No human was around 4.5 billion years ago when the Solar System was formed, so what we know about its birth comes from several sources: examining rocks on Earth and other places, looking at other solar systems in formation and doing computer models, among other methods. This article explores the planets in order of size, with a bit of context as to how they got that way. While humans think of Earth as a large planet, in reality it is dwarfed by the massive gas giants lurking at the outer edges of our Solar System. What also is amazing is the sheer size difference of planets. If you’re interested in planets, the good news is there’s plenty of variety to choose from in our own Solar System. From the ringed beauty of Saturn, to the massive hulk of Jupiter, to the lead-melting temperatures on Venus, each planet in our solar system is unique - with its own environment and own story to tell about the history of our Solar System.
