β Lupi

Beta Lupi is blue-white star 525 light years away. It's just over one binocular field northeast of alpha: binoculars.

Like alpha Lupi, beta is also a young subgiant, about 15 to 20 million years old, and the second brightest star as befitting its Greek label.


If you centre beta in your glasses then move one field east gamma and epsilon Lupi will appear on the northeastern and southern edge of your viewing field respectively. These are both binary systems:
      gamma (h4786)AB: 3.0, 4.5; 276, 0.8". orbit
      epsilon (DUN 182)AB: 3.6, 9.1; 168, 26.0".

Drop south-southwest one field to find mu and kappa Lupi.

These two stars are also fine binaries although mu has an extremely close companion:
      kappa (DUN 177): 3.8, 5.2; 143, 26.5".
      mu (h4753), a multiple star system,
         AB: 4.9, 5.0; 302, 0.9"
         AC: 4.9, 6.3; 128, 23.1".

South one binocular field is zeta Lupi.
