Ross 248 is a faint red dwarf (M - type star) located at 10 light years from us. It is a flare star. There is no evidence of possible planets in the system. See M-Type Stars, Main Sequence Stars and Flare Stars for more information.
The star[]
Ross 248 has 13.6% of our sun's Sol, mass, 16% of its radius and a surface temperature of 2799 K. Its spectral class is M6V. This means it is a dim M - type star and it belongs to the main sequence group of stars. We know it is an eruptive flare star. M6 stars are known to produce massive flares, which can outshine the star even 100 times. As so, Flare Stars like Ross 248 are not suitable for terraforming their planets.
Flares, as they move away from the star, feed a powerful Stellar Wind, which has the power to erode the atmospheres of rocky planets. They are accompanied by massive bursts of UV and X rays, which are ionizing radiations and can also disrupt atmospheres.
Planetary system[]
There is no evidence of any planet orbiting Ross 248. If any planet exists within the system, it must be smaller then Earth or very far away. An Earth-Like Planet would orbit the star at 0.0539 AU. At that distance, the planet would revolve around the star in 12.4 days and will be tidal locked. If such a planet exists, it would be without an atmosphere.
