750 Oskar is a minor planet, specifically an asteroid orbiting in the asteroid belt that was discovered by Johann Palisa on 28 April 1913 in Vienna. 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.[2]
Dust activity due to sublimation has been detected on this asteroid, suggesting the presence of water ice in its interior.[3]
