Lambda Coronae Borealis is a white subgiant star in the constellation Corona Borealis. At 135 light years away, it shines at an apparent visual magnitude of 5.43. Lambda Coronae Borealis is the primary component of a multiple-star system. The star's age is estimated to be 1.6 billion years but is certainly no less than 1.5 billion years and no greater than 1.7 billion years. The iron abundance of Lambda Coronae Borealis is +0.01 (102.3% of the Sun). It is moving through the Galaxy at a speed of 20.4 km/s relative to the Sun. Its projected Galactic orbit carries it between 24,100 and 35,900 light years from the center of the Galaxy. It will come closest to the Sun 1.1 million years from now when it will brighten to magnitude 5.01 from a distance of 111 light years.
