Facts about Ross 154
- 08
Ross 154's luminosity is approximately 0.0005 times that of the Sun, making this nearby red dwarf one of the intrinsically faintest stars visible through telescopes.
- 07
Spectroscopic analysis indicates Ross 154 has a surface temperature of approximately 3,770 Kelvin, making it significantly cooler than our Sun's 5,778 Kelvin surface.
- 06
The habitable zone around Ross 154 extends from approximately 0.05 to 0.1 astronomical units, making it narrow compared to stars like the Sun.
- 05
Flares from Ross 154 can brighten the star by up to 75 percent within seconds, making it one of the most magnetically active red dwarfs known.
- 04
With an estimated mass of 0.17 solar masses, Ross 154 is dim enough that it would require a telescope to observe from Earth despite its proximity.
- 03
Observations of Ross 154 reveal it possesses at least two starspots, indicating intense magnetic activity typical of young red dwarf stars.
- 02
Roughly 9.7 light-years distant, Ross 154 rotates so rapidly that its equatorial velocity reaches approximately 5 kilometers per second, causing visible surface distortion.
- 01
At just 9.7 light-years away, Ross 154 is among the closest red dwarf stars to Earth and was discovered in 1925 by Frank Elmore Ross.
