895 Helio is a large dark outer main-belt asteroid [4] about 150 km in diameter. It was discovered on 11 July 1918 by German astronomer Max Wolf .[2] It is named after the element helium , whose spectrum was studied by Friedrich Paschen and Carl David Tolmé Runge , with the asteroid being named by Paschen at Wolf's request; the name helium itself comes from Helios , the Greek god of the Sun .
This is a B-type asteroid .[2] The best spectral analog for 895 Heloi is the iron rich pyroxene mineral hedenbergite . It shares similar orbital properties with the 31 Euphrosyne asteroid family , but is most likely an interloper.[5] Light curve analysis provides a rotation period of 9.4 hours.[4]
