Quick Solar System facts
The Solar System formed about 4.6 billion years ago from a rotating cloud of gas and dust, and most objects orbit in roughly the same plane.
- Mercury has the shortest year; Neptune has the longest among the planets
- The asteroid belt sits mainly between Mars and Jupiter
- Comets often come from the Kuiper Belt or the distant Oort Cloud
- Jupiter’s gravity strongly shapes many small-body orbits
- A planet’s “day” and “year” can be very different lengths
- Moons can be geologically active, like Europa and Enceladus
