With an apparent magnitude of 12.806, it is too faint to be visible to the naked eye. The radius of the star is 58% that of the Sun.
Interestingly, it is approximately 65% of the mass of the Sun, which means that it is a much larger type of red dwarf than normal. This suggests the star is not as active as a normal red dwarf, causing flares to occur less often than normal. An observation of this star, lasting 80 days, did not record any flares, which is quite impressive for a red dwarf. 
In 2018, a team of astronomers confirmed three Super-Earth planets were orbiting the star. One planet, K2-155 d, is orbiting within the inner edge of the star's habitable zone, which means that liquid water may exist on the planet.
