Photometric observations made in 2012 at the Organ Mesa Observatory in Las Cruces, New Mexico, produced a light curve with a period of 6.2584 ± 0.0002 hours and a brightness variation of 0.21 ± 0.02 in magnitude. This is a member of the Nysa family of asteroids that share similar orbital elements.[3] References1. ^{{Cite web |url=http://ssd.jpl.nasa.gov/sbdb.cgi?sstr=750;cad=1 |title=750 Oskar (1913 RG) |work=JPL Small-Body Database |publisher=NASA/Jet Propulsion Laboratory |access-date=5 May 2016}} [2]2. ^1 {{Citation | editor1-first = Patrick | editor1-last = Moore | editor1-link = Patrick Moore | editor2-first = Robin | editor2-last = Rees | title = Patrick Moore's Data Book of Astronomy | publisher = Cambridge University Press | edition = 2nd | year = 2011 | pages = 164–165 | url = https://books.google.com/books?id=2FNfjWKBZx8C&pg=PA165 | postscript= .}} }} External links
