967 Helionape is anasteroid belonging to theFlora family ofMain Belt asteroids. It was discovered by German astronomerWalter Baade atHamburg Observatory on November 9, 1921, and was named after the Austrian theatrical actorAdolf von Sonnenthal.[2] This object is orbiting the Sun at a distance of2.23 AU with aperiod of 3.32 years and aneccentricity of 0.168. Theorbital plane isinclined at an angle of 5.4° to theecliptic.[1]
Its diameter is about 12 km and it has an albedo of 0.178.[1]Photometric observations in 2007 generated alight curve showing arotation period of3.234±0.002 h. The brightnessamplitude during the measured period was0.058±0.005magnitude.[3]
