RR Ursae Minoris

[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.

It is a single-lined spectroscopic binary system with an orbital period of 2.05 years and an eccentricity (ovalness) of 0.13.

The a sin i value is 84 Gm (0.56 AU),[9] where a is the semimajor axis and i is the orbital inclination to the line of sight from the Earth.

The system is a source for X-ray and far-UV emission, with the latter most likely coming from the companion.

It is radiating 1,580 times the luminosity of the Sun from its enlarged photosphere at an effective temperature of 3,410 K.[12]
