What is Iota Persei

ι Persei is a solar neighbour just 34 light-years away, a yellow subgiant older and more luminous than the Sun but of the same spectral lineage. Its proximity has made it a frequent target for planet searches and astrobiological comparisons. Its light, equivalent to the light that watched several human generations be born, now reaches whoever looks up at Perseus.
