[ 10 ] There are two components: Theta Coronae Borealis A with an apparent magnitude of about 4.2, while Theta Coronae Borealis B lies around 1 arcsecond ...
Sigma Coronae Borealis (σ CrB) is a star system in the constellation of Corona Borealis. It is a quintuple star system containing three sunlike main-sequence stars and two other low-mass stars. The combined visual magnitude is 5.3 and the system lies 74 light years from Earth. σ CrB A is the variable star TZ Coronae Borealis .
