Iota Piscium (ι Psc) is a star 45 light years away from Earth, in the constellation Pisces. The star is a yellowish dwarf (main sequence) star of spectral type F7V, which is somewhat larger and brighter than our sun, but still within the range considered to have the potential for Earth-like planets. It has a surface temperature of about 6,000 to 7,500 kelvins. Iota Piscium is a suspected variable star, and was once thought to have one or two stellar companions, but both are line-of-sight coincidences.[2]
