[9] A rotational lightcurve of Edwardolson was obtained from photometric observations in several locations including the Slovakian Skalnaté pleso Observatory.
It rendered a rotation period of 3.0852±0.0001 hours with a low brightness variation of 0.11 in magnitude, which suggests that the body has a nearly spheroidal shape (U=n/a).
[5][6][7] A minor-planet moon orbiting Edwardolson was discovered in 2005, making it a binary system.
[a] This minor planet was named in honor of American astronomer Edward C. Olson (born 1930) of the University of Illinois whose observations explained the distortion of the outer layers of mass-gaining stars, and how their rotation can come close to the stability limit during the involved mass-transfer process and the preserved angular momentum.
[2] Olson was also an active member of the International Astronomical Union, affiliated with its Division G Stars and Stellar Physics.
