Scientists have revealed that when you look into the night sky, you may be seeing a lot of "ploonets".
In other solar systems, some moons might escape their planets and orbit their stars, just like the planets, researchers said.
Scientists have invented the superb word "ploonets" to describe such moons and hope they can be detected with today's telescopes.
Researchers believe that moons could be "ejected" from their orbits around "hot Jupiters" – vast planets that sit near their stars and bathe in intense heat.

'Hot Jupiters' begin further and are gravitational inward – during which intense gravitational forces could eject their moons, turning them into 'ploonets'.
Mario Sucerquia, of the University of Antioquia in Medellín, Colombia, said: "This process should occur in all planetary systems composed of a giant planet located in a very close orbit.
"So, ploonets should be very common."
Sucerquia and his team believe that the "ploonets" could explain the strange "darkening" of other stars already detected by telescopes on Earth.
