It was discovered by N.R. Pogson on April 17, 1861, from the Madras Observatory. Pogson chose the name to refer both to Asia, a Titaness in Greek mythology, and to the continent of Asia, because the asteroid was the first to be discovered from that continent.[2] Photometry from the Oakley Observatory during 2006 produced a lightcurve that indicated a sidereal rotation period of {{Val|15.90|0.02}} with an amplitude of {{Val|0.26|0.04}} in magnitude.[6] It has a 2:1 commensurability with Mars, having an orbital period double that of the planet.[7]References1. ^Asteroid Data Sets {{webarchive|url=https://www.webcitation.org/5mqof7ROl?url=http://www.psi.edu/pds/resource/albedo.html |date=2010-01-17 }} See Table 1.[3][4]2. ^{{cite book|last=Schmadel|first=Lutz D.|title=Dictionary of Minor Planet Names|url=https://books.google.com/books?id=KWrB1jPCa8AC&pg=PA22|year=2003|publisher=Springer Science & Business Media|isbn=978-3-540-00238-3|page=22}} 3. ^1 {{citation | title=Resonant asteroids and the equivalence principle | last1=Plastino | first1=A.
