What we do know is that the Sun's siblings are definitely out there.

Does the Sun have a twin?

The team's research has been published in the journal Astronomy & Astrophysics. It's thought that somewhere out there, the Sun has a twin - born not just in the same stellar nursery, but an almost identical twin, a binary companion made of the same star-stuff.

What would happen if Earth had two suns?

All water on our planet would be frozen, and no life would have formed thanks, also, in part to Earth being farther from the sun than 16b is to its star system [source: Wolchover]. Other scientists suggest that day and night would have completely different meanings on an Earth with two suns.

Did our Solar System once have a twin?

If the LSST's first long scan of space reveals Planet 9 and a large population of additional dwarf planets in the Oort cloud that will strongly suggest our solar system once had a twin, he said. Wherever that stellar twin ended up, if it existed, we'll never find it again, Loeb said.
