Template:Short description Template:Starbox begin Template:Starbox observe Template:Starbox character Template:Starbox astrometry Template:Starbox detail Template:Starbox catalog Template:Starbox reference Template:Starbox end Delta Leporis which is latinized from δ Leporis is a solitary,[1] orange-hued star in the southern constellation of Lepus. It is visible to the naked eye with an apparent visual magnitude of 3.85.[2] Based upon an annual parallax shift of 28.68 mas,[3] it is 114 light years distant from Earth.
This is an old, evolved K-type star with an age of about 10.7 billion years.[4] Keenan and McNeil (1989) classified it as Template:Nowrap,[5] indicating it is a giant star showing a deficiency of iron and an excess of cyanogen in its atmosphere. However, Gray et al. (2006) listed it as Template:Nowrap,[6] which would suggest a less evolved subgiant star. It may be a red clump star, which indicates it is generating energy through helium fusion at its core.[7]
The measured angular diameter of this star, after correction for limb darkening, is Template:Val.[8] At the estimated distance of this star, this yields a physical size of about 10 times the radius of the Sun.[9] It has only 94%[4] of the Sun's mass and is radiating 46[4] times the Sun's luminosity from its photosphere at an effective temperature of 4,660 K.[10]
