A mysterious planet — called Planet 9 or Planet X — may be hiding at the edge of our solar system.
The number of known planets in our solar system has risen and fallen over time.
From the six worlds known to ancient people (including Earth), astronomers have found the planets Uranus and Neptune.
Planet 9 would likely be a gas giant, hiding on the edge of our solar system (lighting for effect).
At that point, the solar system was said to contain 13 planets (including Neptune, first seen in 1846), and the number of recognized planets was reduced to just eight members.
Despite its classification of Pluto as a dwarf planet, it is now recognized as the first Trans-Neptunian Object (TNO), and the first member of the Kuiper Belt, ever found.
