Nu2 Coronae Borealis
Nu2 Coronae Borealis is a solitary, orange-hued star located in the northern constellation of Corona Borealis. It is faintly visible to the naked eye, having an apparent visual magnitude of +5.4. Based upon an annual parallax shift of 5.49 mas, it is located roughly 590 light years from the Sun. At that distance, the visual magnitude is diminished by an extinction of 0.1 due to interstellar dust. This is an evolved red giant star with a stellar classification of K5 III. The measured angular diameter of Nu2 Coronae Borealis is . At its estimated distance, this yields a physical size of about 50 times the radius of the Sun. Nu2 Coronae Borealis is radiating 530 times the Sun's luminosity from its photosphere at an effective temperature The effective temperature of a body such as a star or planet is the temperature of a black body that would emit the same total amount of electromagnetic radiation. Effective temperature is often used as an estimate o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
