3757 Anagolay, provisional designation 1982 XB, is an eccentric, stony asteroid, classified as a near-Earth object and potentially hazardous asteroid. It belongs to the group of Amor asteroids and measures about half a kilometer in diameter. It was discovered by American astronomer Eleanor Helin at the U.S. Palomar Observatory, California, on 14 December 1982.[2]
The silicaceous S-type asteroid orbits the Sun at a distance of 1.0–2.7 AU once every 2 years and 6 months (908 days). Its orbit shows a high eccentricity of 0.45 and an inclination of 4 degrees from the plane of the ecliptic. The asteroid is a potentially hazardous asteroid because its Earth minimum orbit intersection distance (MOID) is less than 0.05 AU and its diameter is greater than 150 meters. The Earth-MOID is 0.0369 AU (5,500,000 km). Its orbit is well-determined for the next several hundred years.[1]
Based on light-curve observations in the 1980s, the asteroid has a rotation period of 9.012 hours and a brightness amplitude of 0.20 in magnitude.[4][5] The body's albedo lies between 0.18 and 0.34,[1][3] with the Collaborative Asteroid Lightcurve Link deriving an intermediate albedo of 0.26.[7]
The body was named after Anagolay, the goddess of lost things worshipped by pre-Hispanic Tagalogs. In Philippine mythology, Anagolay is the daughter of the hermaphroditic agricultural deity Lakampati, who in some sources is the goddess Ikapati; the latter scenario has Anagolay's father named as Mapulon, god of the seasons.[8] The name, suggested by Filipino student Mohammad Abqary Alon, bested 85 other entries in a contest held by the Space Generation Advisory Council's "Name-An-Asteroid" campaign.[2][9]
