[ located approximately 480[1] light years away from the Sun. It has the Bayer designation e Leonis; 87 Leonis is the Flamsteed designation. This object is visible by the naked eye as a faint orange-hued star with an apparent visual magnitude of 4.77.[3] It is moving away from the Earth with a heliocentric radial velocity of 19 km/s.[3] The star is positioned near the ecliptic and thus is subject to occultation by the Moon.[25]]This is an aging K-type giant star with a stellar classification of {{nowrap|K3+ III Fe−0.5}},[4] which means it has exhausted the hydrogen at its core and evolved away from the main sequence. The suffix notation indicates a mild underabundance of iron in the atmosphere. It has expanded to 37[27] times the Sun's radius and is radiating over a thousand[3] times the Sun's luminosity from its photosphere at an effective temperature of 4,001 K.[15]
