Hassaleh in Becvar — Star in Auriga
HIP 23015; Iota Aurigae; 3 Aurigae
About Hassaleh in Becvar
Description
Hassaleh is an orange giant of spectral type K3II at magnitude 2.69 in Auriga. Located about 490 light-years from Earth, it is a fairly luminous evolved star with roughly 2,600 times the Sun's luminosity and a diameter about 130 times solar. Hassaleh forms part of the small triangle of stars known as 'the Kids' (Haedi) near Capella.
Observing Tips
Look for Hassaleh as part of a small triangle of stars just south of brilliant Capella — this is the Kids asterism (Iota, Eta, and Zeta Aurigae). Its warm orange color contrasts with the blue-white of Eta Aurigae nearby. Best observed from November through April when Auriga rides high in the winter sky.
History
The name Hassaleh is derived from the Arabic 'al-'anz,' meaning 'the she-goat,' though this name is more commonly associated with nearby Epsilon Aur. The 'Kids' asterism near Capella (the Mother Goat) represents baby goats in the mythological story. In medieval European astronomy, the Kids were considered important weather indicators.
Fun Facts
The three Kids stars near Capella (Iota, Eta, and Epsilon Aurigae) are all very different types of stars despite appearing close together — Iota is a distant orange giant, Eta is a hot B-type star, and Epsilon is one of the most mysterious eclipsing binaries in the sky with a dark companion of unknown nature.
