58 Eridani is a main-sequence star in the constellation Eridanus. It is a solar analogue,[12] having similar physical properties to the Sun. The star has a relatively high proper motion across the sky, and it is located 43 light years distant. It is a probable member of the IC 2391 moving group of stars that share a common motion through space.[10]
