47 UMa
Hover mouse cursor over each image to turn on its star labels.
Near the edge of the Solar neighborhood, 47 Ursae Majoris is relatively close, on the galactic scale — at roughly 14 parsecs (45 light years).
The view on the right labels some of the brighter stars in Earth's night skies, and labels our sun and 47 UMa, as well. Theta UMa and Iota UMa are labelled in this and the next 3D view. |

Scale = 16 parsecs.
47 Ursae Majoris is highlighted by the green "focus" marker.
Our own sun is located at the white diamond.

The next 3D view zooms in for a closer look at the region surrounding 47 UMa. Here the sides of the "viewing cube" are 8 parsecs (26.1 light years) long. It would take light, traveling at 186,000 miles per second, over a quarter century to travel along one edge, from corner to corner.
When you hover your mouse cursor over this 3D view, additional stars appear. These are the dim, red dwarf stars close to 47 UMa.
The next 3D view (below the following table) zooms in even farther to the 4-parsec scale.

Next-Door Neighbors: 47 UMa
The following table is a list of 47 UMa's next-door neighbors. After the star's name, the distance from 47 UMa is given in parsecs. This is followed by the distance from Sol (our sun), the Spectral Type, Visual Magnitude, and number of stars in the system. The Spectral Type and Visual Magnitude are given for the primary star, if there are more than one in the system. The magnitudes given are those of the stars as seen from 47 Ursae Majoris.

At the 4-parsec scale, there are only four systems visible besides 47 UMa. Gliese 378 and 400 would be barely visible in the night skies of 47 UMa, even under excellent seeing conditions. HD 101206 would be a dim 5th magnitude star, while Gliese 397 would shine a little brighter as a 4th magnitude star.
