The M81 Group is a galaxy group in the constellations Ursa Major and Camelopardalis that includes the galaxies Messier 81 and Messier 82, as well as several other galaxies with high apparent brightnesses. [1] The approximate center of the group is located at a distance of 3.6 Mpc, making it one of the nearest groups to the Local Group. [1]
Early illustration showing how many of the stars in Ursa Major move in a group. The Ursa Major Moving Group, also known as Collinder 285 and the Ursa Major association, is the closest stellar moving group – a set of stars with common velocities in space and thought to have a common origin in space and time.
Ursa's primary functions include advancing amateur astronomy and astronomical education. [1] They have published a magazine Tähdet ja avaruus since 1971 and have provided awards to exceptional members of amateur astronomy for significant astronomical observations since 1988. [2] [3] Anyone can join Ursa for an annual fee. [4]

47 Ursae Majoris is the Flamsteed designation.On their discoveries the planets were successively designated 47 Ursau Majoris b, c and d. In July 2014 the International Astronomical Union launched NameExoWorlds, a process for giving proper names to certain exoplanets and their host stars. [11]
Epsilon Ursae Minoris (ε Ursae Minoris) is a binary star [10] system in the northern circumpolar constellation of Ursa Minor. It is visible to the naked eye with a combined apparent visual magnitude of 4.19. [2] Based upon an annual parallax shift of 10.73 mas as seen from the Earth, it is located around 300 light years from the Sun.
