Sunday night’s Supermoon, aka the ‘Full Cold Moon,’ is the first of three such consecutive lunar events in which our satellite will appear bigger and brighter.
A supermoon occurs when the moon’s orbit comes closest to the Earth, a point known as the perigee, when it appears up to 14 percent bigger and 30 percent brighter than the furthest point away, known as the apogee (roughly 30,000 miles (50,000 km) from the Earth).
