It was discovered by French astronomer Henri Joseph Perrotin on April 26, 1876, and named after one of the two Erigones in Greek mythology. This asteroid is orbiting the Sun at a distance of 2.37 AU with a period of 1330.5 days years off out and an eccentricity (ovalness) of 0.19. The orbital plane is inclined at an angle of 4.8° to the plane of the ecliptic. Photometric measurements taken in 2014 were used to construct a lightcurve that demonstrated a rotation period of 16.136 0.001 hours with an amplitude of 0.32 0.02 in magnitude. Erigone is a relatively large and dark asteroid with an estimated size of 73 km. Based upon its spectrum, it is classified as a C-type asteroid, which indicates that it probably has a carbonaceous composition. It is the largest member of the eponymously named Erigone collisional family. 2014 occultation of Regulus thumb|left|Path of occultation from New York to Ontario In the early morning hours of March 20, 2014, Erigone occulted the first-magnitude star Regulus, as first predicted by Aldo Vitagliano in 2004 using the SOLEX software. This would have been a rare case of an occultation of a very bright star visible from a highly populated area, since the shadow path moved across New York state and Ontario, including all five boroughs of New York City. Observers in the shadow path would have seen the star wink out for as long as 14 seconds. However, thick clouds and rain blocked the view for most if not all people on the shadow path.Asteroid eclipse rained out Space.com 2014 March 20 The website of the International Occultation Timing Association does not list any successful observations at all.Regulus 2014 https://web.archive.org/web/20201121183357/http://occultations.org/Regulus2014/ 21 November 2020 International Occultation Timing Association Two single chord Asteroid Occultation events have been observed, in 2013 and 2015.https://sbn.psi.edu/pds-staging/resource/occ.html PDS Asteroid/Dust Subnode sbn.psi.edu en 2018-04-25 https://web.archive.org/web/20180425115705/https://sbn.psi.edu/pds-staging/resource/occ.html 2018-04-25 dead References Rotation Period Determination for 163 Erigone 1 Pilcher Frederick Briggs John W.
