Facts about Algenib
- 09
Classified as a Beta Cephei variable star, Algenib pulsates with slight variations in brightness and radius over a period of a few hours.
- 08
Spectroscopic analysis reveals that Algenib possesses a powerful stellar wind ejecting material at approximately 2,000 kilometers per second into surrounding space.
- 07
Gamma Pegasi's designation as the third-brightest star in Pegasus rather than the primary star stems from historical naming conventions established before modern brightness measurements confirmed its superior luminosity.
- 06
Algenib rotates approximately 75 times faster than our Sun, completing one full rotation in roughly 1.2 days due to its massive size and young stellar age.
- 05
With a mass approximately 7 times greater than our Sun, Algenib will eventually exhaust its hydrogen fuel and evolve into a white dwarf within the next few million years.
- 04
Approximately 8.6 million years ago, light from Algenib began its journey toward Earth, meaning we observe the star as it appeared during the Miocene epoch.
- 03
Algenib's surface temperature reaches approximately 10,000 Kelvin, classifying it as a blue giant star in the spectral class B2.
- 02
Located approximately 390 light-years from Earth, Algenib ranks as the brightest star in the constellation Pegasus despite being designated Gamma rather than Alpha.
- 01
The star Algenib, also known as Gamma Pegasi, shines with approximately 5,000 times the luminosity of our Sun.
