Messier 81 is the largest galaxy in the M81 Group, a group of 34 in the constellation Ursa Major. [28] At approximately 11.7 Mly (3.6 Mpc) from the Earth, it makes this group and the Local Group, containing the Milky Way, [28] relative neighbors in the Virgo Supercluster.
NGC 3941 is a barred lenticular galaxy located in the constellation Ursa Major.It is located at a distance of circa 40 million light years from Earth, which, given its apparent dimensions, means that NGC 3941 is about 40,000 light years across.
Book plate by Sidney Hall depicting Ursa Major's stars A light curve for Epsilon Ursae Majoris, plotted from TESS data [11] According to Hipparcos, Epsilon Ursae Majoris is 81 light-years (25 parsecs) from the Sun. Its spectral type is A1p; the "p" stands for peculiar, as its spectrum is characteristic of an α 2 Canum Venaticorum variable ...
