Yes, probably billions! Planets orbiting other stars are incredibly common and are called exoplanets, and a lot of them are weirder than we could ever imagine. One is so close to its star that its sun-facing side is entirely lava while the other is frozen solid; another orbits three stars at once; another is so arch in carbon that it’s probably 1/3 pure diamond.
My favourite is the Trappist-1 system, named after the telescope that discovered it: it has seven known planets and three of them could have liquid water.
