It was discovered on 14 December 1982, by American astronomer Eleanor Helin at the Palomar Observatory in California, United States. The asteroid was named after Anagolay from Philippine mythology.[2] Orbit and classificationAnagolay orbits the Sun in the inner main-belt at a distance of 1.0–2.7 AU once every 2 years and 6 months (908 days). Its orbit has an eccentricity of 0.45 and an inclination of 4° with respect to the ecliptic.It 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. Its Earth-MOID is {{convert|0.0386 |AU |km |abbr=on |lk=off |sigfig=3}} which corresponds to 15 lunar distances. Its orbit is well-determined for the next several hundred years. The body's observation arc begins in 1986, as no precoveries and no identifications prior to its discovery were made.[2] Physical characteristicsIn the Tholen classification, Anagolay is a silicaceous S-type asteroid. Based on two rotational lightcurves obtained in the 1980s, Anagolay has a rotation period of 9.012 hours and a brightness variation of 0.20 and 0.21 in magnitude, respectively ({{small|U=n.a.}}).[10][11] A third lightcurve, also from the 1980s, gave an alternative period of {{val|9.0046|0.0013}} hours with an amplitude of 0.14 ({{small|U=2-}}).[9] The body's albedo lies between 0.18 and 0.34,[7] with the Collaborative Asteroid Lightcurve Link (CALL) deriving an intermediate albedo of 0.26. CALL also assumes a diameter of 390 meters.[6] NamingThis minor planet 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 (also goddess Ikapati).[34] The name, suggested by Filipino student Mohammad Abqary Alon, was selected among 85 other suggestions in a contest held by the Space Generation Advisory Council's "Name-An-Asteroid" campaign.[2][36] The official naming citation was published by the Minor Planet Center on 9 September 2014 ({{small|M.P.C. 89832}}).[37] References1. ^1 2 3 4 5 {{cite web |title = 3757 Anagolay (1982 XB) |work = Minor Planet Center |url = http://www.minorplanetcenter.net/db_search/show_object?object_id=3757 |accessdate = 1 February 2016}} [1][2][3][4][5][6][7][8][9][10]2. ^1 {{cite web |title = MPC/MPO/MPS Archive |work = Minor Planet Center |url = http://www.minorplanetcenter.net/iau/ECS/MPCArchive/MPCArchive_TBL.html |accessdate = 30 May 2016}} 3. ^1 {{cite web |website = FilipiKnow |title = An Ultimate Guide To Philippine Mythology’s Legendary Deities |date = 2018 |url = https://filipiknow.net/philippine-mythology-gods-and-goddesses/#8_Anagolay |accessdate = 2 December 2018}} 4. ^1 {{cite web |last1 = Montenegro |first1=Bea |title = New asteroid named after Philippine goddess of lost things |url = http://www.gmanetwork.com/news/story/382869/scitech/science/new-asteroid-named-after-philippine-goddess-of-lost-things |website = GMA News Online |accessdate = 26 August 2015 |date = 9 October 2014}} 5. ^1 2 3 4 {{cite web |title = LCDB Data for (3757) Anagolay |publisher = Asteroid Lightcurve Database (LCDB) |url = http://www.minorplanet.info/PHP/GenerateALCDEFPage_Local.php?AstInfo=3757%7CAnagolay |accessdate = 30 May 2016}} 6. ^1 2 3 4 {{Cite journal |author = Harris, Alan W. |date = February 1998 |title = A Thermal Model for Near-Earth Asteroids |url = http://adsabs.harvard.edu/cgi-bin/bib_query?bibcode=1998Icar..131..291H |journal = Icarus |volume = 131 |issue = 2 |pages = 291–301 |bibcode = 1998Icar..131..291H |doi = 10.1006/icar.1997.5865 |access-date= 30 May 2016}} 7. ^1 2 {{Cite journal |first1 = A.
