Pi 1 Ursae Minoris [14] is a common proper motion binary star [15] system in the northern circumpolar constellation of Ursa Minor. The pair have apparent visual magnitudes of +6.58 and +7.31, with a combined magnitude of 6.1. [2] They are located about 71 light years from the Sun.
RR Ursae Minoris, abbreviated RR UMi, is a binary star [13] system in the northern circumpolar constellation of Ursa Minor. It can be viewed with the naked eye, typically having an apparent visual magnitude of around 4.710. [10] Based upon an annual parallax shift of 7.1 mas [8] as seen from Earth's orbit, it is located 460 light years away.
R Ursae Minoris is a star in the constellation Ursa Minor. A red giant of spectral type M7IIIe, it is a semiregular variable ranging from magnitude 8.5 to 11.5 over a period of 325 days. [3] In 1881, Edward Charles Pickering announced that the star, at that time unnamed, is a variable star. [8]
Lambda Ursae Minoris (λ UMi, λ Ursae Minoris) is a star in the constellation Ursa Minor. It is an M-type red giant with an apparent magnitude of +6.38, making it very faintly visible to the naked eye under the best observing conditions. It is approximately 880 light years from Earth.
