names=58 Eri, Gl 177, HR 1532, BD -17°954, HD 30495, LTT 2088, GCTP 1070.00, SAO 149888, HIP 22263.58 Eridani is a
main sequence star in theconstellation Eridanus. It is considered a solar analogue, [cite journal | author =E.J. Gaidos, G.W. Henry, S.M. Henry | title=Spectroscopy and Photometry of Nearby Young Solar Analogs | journal=Astronomical Journal | year=2000 | volume=120 | pages=1006–1013 | url=http://adsabs.harvard.edu/abs/2000AJ....120.1006G | doi=10.1086/301488 ] which means it has similar physical properties to theSun . The star has a relatively highproper motion across the sky, and it is located about 44light year s distant.The
x-ray emissions from this star'scorona indicate an age of less than a billion (109) years, [cite journal | author =E.J. Gaidos, G. Gonzalez | title=Stellar Atmospheres of Nearby Young Solar Analogs | journal=New Astronomy | year=2002 | volume=7 | pages=211–226 | url=http://adsabs.harvard.edu/abs/2002astro.ph..3518G | doi=10.1016/S1384-1076(02)00108-2 ] compared to 4.6 billion for the Sun, so it is still relatively young for a star of its mass.Starspot activity has also been detected, which varies from year to year.A circumstellar disc of dust particles has been detectedin orbit around 58 Eridani.
