Sky Position:
When you move your mouse cursor over the Sky Map, at left, you can see that 47 Ursae Majoris is several degrees south of the bowl of the "Big Dipper" — the most recognizable part of the Big Bear (Ursa Major). At nearly 14 parsecs (45 light years) from Earth, 47 UMa is amazingly dim for a star that is so much like our own sun. |

View from 47 Ursae Majoris toward Gliese 397 and beyond to the Perseid Expanse. |

Alien Skies™:
The view from 47 UMa of one of its closest neighbors — the dim K7 V red dwarf, Gliese 397 (green "focus" marker). Even though the neighboring star is little more than 2 parsecs away, it is rather unspectacular in brightness.

Alien Skies™:
Looking back toward our home, Sol is barely visible at 13.9 parsecs. The fact that our sun is so dim in their night skies brings home the utter vastness space.
Our sun is tagged by the yellow focus marker when you hover your mouse cursor over the Sky Map. Cursor over either the yellow or green marker will reveal the distance view.
