It was discovered on 21 July 1928, by astronomer Harry Edwin Wood at the Union Observatory in Johannesburg, South Africa.
[17] The asteroid was named after South African engineer Theodore Reunert, supporter of the observatory and friend of the discoverer.
[3] Since 2000, several rotational lightcurves of Reunerta were obtained from photometric observations by Robert Stephens, Roberto Crippa and Federico Manzini, as well as by astronomers at the Palomar Transient Factory in California.
Analysis of the best-rated lightcurve gave a rotation period of 13.036 hours with a brightness amplitude of xyz magnitude (U=2/2/2/3).
[5][6][7][8][9][10][11] The Collaborative Asteroid Lightcurve Link derives an albedo of 0.0445 and a diameter of 45.65 kilometers based on an absolute magnitude of 10.7.
