A scenario for transfer of life by this means might require life or a precursor molecule to be shielded from radiation for millions of years, dormant within an outgoing chunk of planetary debris a meter or more in diameter that is produced by a meteorite impact, until this new meteorite impacts on a different planet.

The star is considered to be a stellar sibling of the Sun and is the first such sibling to be discovered. Solar siblings are those stars that formed from the same gas cloud and in the same star cluster; the term was introduced in 2009. No planets have been detected orbiting HD 162826, but due to

The discovery of a first solar sibling by searching for specific rare elements may make it easier to identify other siblings in the future. However, HD 162826 is probably the nearest solar sibling, because others would have been identified first if they had been closer to the Sun. It had not
