Solar Siblings

Turbulence in stellar nurseries will cause groups of stars from the same cloud to be scattered relatively quickly. There’s no reason to think that the current nearest stars to the sun are our siblings, though we probably do have sibling stars out there somewhere. Scientists have probably found a star (HD 162826) that formed from the same molecular cloud as our sun about 110 light-years away. This star might have shared the stellar nursery the sun was born in about 4.6 billion years ago. This star is 15 percent more massive than the sun, so it can’t be called a solar twin, just a solar sibling.
