RS Coronae Borealis is a semiregular variable star located in the constellation Corona Borealis with a parallax of 2.93mas being a distance of 341 parsecs (1,110 ly). [1] It varies between magnitudes 8.7 to 11.6 over 332 days. [2] It is unusual in that it is a red star with a high proper motion (greater than 50 milliarcseconds a year). [4] Located around 1072 light-years distant, it shines with a luminosity approximately 1839 times that of the Sun and has a surface temperature of 3340 K. [5]
