Mu2 Boötis
Appearance
(Redirected from Μ2 Boötis)
Mu2 Boötis is a binary star in the northern constellation of Boötes. Its name is a Bayer designation that is Latinized from μ2 Boötis, and abbreviated Mu2 Boo or μ2 Boo. Based on parallax measurements, these stars are located at a distance of approximately 120 light-years from the Sun.
The components of μ2 Boötis have apparent magnitudes of +7.0 and +7.6.[2] They have similar spectral types, F9V and G0V respectively, and complete one orbit about their common centre of mass every 260 years.[4]
The system μ1 Boötis is at a similar distance and share similar proper motions with μ2, but has a significantly different chemical composition, so they are not gravitationally bound.[4]
