The planets of our planetary system.

A Planetary System is a system of non-stellar natural satelites orbiting a central star. Sometimes, instead of orbiting one star, the planets can orbit around two stars in a binary system, or even a trinary system. This includes planets, dwarf planets, asteroids, comets, etc. The stars can be of any luminosity, mass and diameter. Every star has its own habitable zone, which allows for certain planets within that region to be capable of having advanced life, thanks to appropriate conditions. Unlike the solar system, which also includes the star(s), the planetary system is only about the planets. As such, while the solar system can extend upwards of >1 light year, the planetary system only stretches to a couple astronomical units.

Our planetary system

The dwarf planet Farout (2018 VG18) has a semi-major axis of roughly 81.3 AU, which is as far as the planetary system stretches, whilst only including normal planets gets you to Neptune at a round 34 AU.

Our planetary system includes the following objects:
