Wolf 359

Star type
g M5.8 Ve

Distance from Earth
g 7.797 ly

Star Service No.
g NA

g 10 Gy

g 16% to 19%; 9.2% to 13%; 2230-2600 K

Brightness (xSol)
g 2/100,000; very cool, main sequence red dwarf; flare star so can brighten dramatically from time to time, but flares rarer and not as violent as those observed on Proxima Centauri, Kruger 60 B or UV Ceti

g NA

Comparison to Sol
g NA

Star system features
g A fairly extreme red dwarf

Known planets
g None known

Habitable zone
g 0.0042 AU with orbital period of around 8 hours but tidally locked; light emitted by red dwarfs may be too red in color for Earth-type plant life to perform photosynthesis efficiently; at 1 AU, would need a telescope to see its round shape clearly, and daylight would be very dim with only 10 times brightness of full moonlight. On planet 1 AU from star, would need telescope to make out stars' ball shape.
