331 Etheridgea
331 Etheridgea is a large main belt asteroid. It was discovered by Auguste Charlois on 1 April 1892 in Nice. The meaning of the name is unknown. This asteroid is orbiting the Sun at a distance of with a period of and an eccentricity (ovalness) of 0.10. The orbital plane is tilted at an angle of 6.05° to the plane of the ecliptic. Analysis of the asteroid light curve generated from photometric data collected in 2015 provided a rotation period of . This result is completely different from the previous rotation period estimates. It is a low albedo, carbonaceous C-type asteroid and spans a girth of . It may have been named for the geologist and paleontologist Robert Etheridge (1819–1903).
