α Lupi

Alpha Lupi, a blue giant 550 light years away, forms the southwestern corner of the asterism. It's easily found by moving due north of alpha Centauri a little over two binocular fields, or due east from zeta Centauri one field of view: binoculars.

Alpha Lupi is just a baby at 20 million years old, and is now about 10 times the size of our sun; it may have a 14th magnitude companion, or it may just be optical: 2.3, 14; 235, 24.3".

A wide binary in this field is the blue subgiant tau1 (DUN 160) AB: 4.5, 8.9; 205, 157".

Between alpha and tau is h4690, which has a nice colour contrast, orange and white: 5.6, 7.7; 24, 19.2".

Beta is just over a binocular field north-northeast. Click on beta on the map to continue.
