What is a rogue planet?

A rogue planet is a planetary-mass object that does not orbit a star. They drift through interstellar space, having been ejected from their original solar systems by gravitational interactions.

How can a planet stay warm without a sun?

They stay warm through radiogenic heating (the decay of elements in the core) and insulation from thick atmospheres, often rich in hydrogen, which acts as a powerful greenhouse gas.

How do we find rogue planets if they are dark?

Astronomers use gravitational microlensing, observing how the planet’s gravity bends the light of a distant star as it passes in front of it.
