Understanding Arcturus: The Star at a Glance
Basic Stellar Characteristics
- Type: K1.5 III red giant
- Distance from Earth: Approximately 36.7 light-years
- Apparent Magnitude: -0.05, making it the fourth brightest star visible from Earth
- Size: About 25 times the diameter of the Sun
- Mass: Nearly 1.08 times that of the Sun
- Luminosity: Approximately 170 times solar luminosity
The Significance of Arcturus
Arcturus is part of the Boötes constellation and is notable not only for its brightness but also for its advanced evolutionary stage. Its status as a red giant indicates that it has exhausted hydrogen in its core and has expanded significantly. Studying Arcturus helps astronomers understand stellar evolution and the lifecycle of stars similar to our Sun.
