SOLAR SYSTEM

8 PLANETS + 19 DWARF PLANETS

There are eight "classical" planets and 19 widely-recognized (but not univerally accepted) dwarf planets in our solar system.

Classical planets

These are the eight planets that have been known for hundreds if not thousands of years. Pluto was discovered in 1930 and demoted as a planet in 2006. Planets are shown by distance from the Sun.

Asteroid (main) belt dwarf planets

There are two dwarf planets located in the Main (asteroid) belt.

Kuiper belt dwarf planets

There are 16 widely-recognized dwarf planets located in the Kuiper belt past Neptune. The outer Kuiper belt is sometimes called the scattered disc. Planets are shown by distance from the Sun.

Inner Oort cloud dwarf planets

Planets here are in very elongated orbits that go from the Kuiper Belt out to the inner edge of the Oort Cloud. Several dwarf planets and asteroids out there are believed to be perturbed by Planet 9, thought to be 5x Earth mass. It's existence is suggested but by no means confirmed. Planets are shown by distance from the Sun.

The Earth is the cradle of humanity, but mankind cannot stay in the cradle forever.
