Taking luminosity $L = L_\odot (R/R_\odot)^2 (T/T_\odot)^4$, at a distance of 1AU would be significantly brighter than the full moon. Artists' depictions and wikipedia descriptions are silly sometimes. | |

(And remember than Mars is small. This planet is big, so that it would reflect the same amount of light as Mars even if its albedo was only 1/4 of that of Mars.) | |
