11 Ursae Minoris is a single[6] star located approximately 410 light years away[1] in the northern circumpolar constellation of Ursa Minor. The star is visible to the naked eye as a faint, orange-hued star with an apparent visual magnitude of 5.15.[2] It is moving closer to the Earth with a heliocentric radial velocity of −17.5 km/s.[1]
This is an aging K-type giant star with a stellar classification of K4 III.[3] It is 1.2 billion years old with twice the mass of the Sun.[3] As a consequence of exhausting the hydrogen at its core, the star has expanded to 28 times the Sun's radius.[3] It is radiating 258 times the luminosity of the Sun from its swollen photosphere at an effective temperature of 4,358 K.[3]
11 Ursae Minoris is sometimes named Pherkard or Pherkad Minor, the later name to distinguish it from Pherkad (Major) which is γ Ursae Minoris. It has also been designated as γ1 Ursae Minoris, in which case the brighter Pherkad is called γ2 Ursae Minoris, but these names are rarely used.[7]11 Ursae Minoris is the Flamsteed designation.
11 Ursae Minoris has a detected planet discovered in August 2009.[4]
