Facts about Ross 248
- 07
Observations suggest Ross 248's luminosity at approximately 0.001 solar luminosities makes it nearly 100,000 times fainter than our Sun despite being one of the nearest stars to Earth.
- 06
Spectral analysis reveals Ross 248 belongs to the M5.5 spectral class, indicating a surface temperature around 3,100 Kelvin cooler than our Sun's 5,778 Kelvin.
- 05
The stellar companion of Ross 248, a white dwarf, orbits at a distance of approximately 220 astronomical units with an estimated orbital period exceeding 200,000 years.
- 04
Discovered by Frank Elmore Ross in 1926, this red dwarf star exhibits a proper motion of 10.75 arcseconds per year, among the fastest-moving stars in Earth's celestial neighborhood.
- 03
A mass of approximately 0.1 solar masses makes Ross 248 one of the smallest and dimmest red dwarf stars observable from Earth's perspective.
- 02
Ross 248's apparent magnitude of 12.29 makes it invisible to the naked eye despite being the tenth-closest star system to Earth at approximately 10.3 light-years away.
- 01
In approximately 36,000 years, the red dwarf Ross 248 will become Earth's nearest stellar neighbor, closer than Proxima Centauri's current 4.24 light-year distance.
