This weekend the moon was full and in perigee and therefore appeared bigger and brighter than usual, a so-called supermoon.
Perigee is the point at which the earth is closest to some object that orbits it in an elliptical path. Apogee is the point of greatest distance between the Earth and a satellite. For stuff orbiting the sun (such as the earth) the analogous points are called perihelion and aphelion.
