What is 43 Ursae Majoris

43 Ursae Majoris is an orange giant 357 light-years away, an angular neighbour of 42 UMa in the sky of the Great Bear. Though they look almost glued together, their light comes from very different epochs and distances: the physical gap is many light-years. It is a recurring illusion of the night sky, where two points near to our eye may live in separate cosmic rooms. Its light set out in the early seventeenth century, in the thick of the telescopic revolution.

Where it is and when to see it

43 Ursae Majoris lies in the northern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is February, when it culminates around midnight.

From London it never sets and culminates about 85° up.
From New York it never sets and culminates about 74° up.
From Sydney it never rises above the horizon.

It can be seen from anywhere north of 33° S.

It ranks no. 79 in brightness among the 124 stars of Ursa Major in our catalogue. To find it, start from Alioth, the brightest: it lies about 17° away (a fist at arm's length covers about 10°).

The light you see today left it about 360 years ago.
