About: KU Hydrae

An Entity of Type: star, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

KU Hydrae is a binary star in the constellation Hydra. The primary star is an Alpha2 Canum Venaticorum variable with its apparent magnitude varying from 0.05 magnitudes over a period of 33.97 days. This star was discovered to be a visual binary star by Robert Grant Aitken in 1906 and was given the double star designation A 1342. Additional measurements of the position angle and angular separation showed a rapid orbital motion.
