A bigger and brighter full moon will light up the Toronto sky on Saturday night — one of three such “supermoons” appearing this year.

According to NASA, the full moons on Aug. 10 and Sept. 9 will also look 14 per cent bigger and 30 per cent brighter as the moon passes 50,000 kilometres closer to earth.

The scientific term for the phenomenon is “perigee moon” — referring to the point in the moon’s elliptical orbit closest to earth.

Generally, perigee moons happen every 13 months and 18 days, an expert from the U.S. Naval Observatory said. Three occurred in a row last year as well.

For viewing, Environment Canada said Saturday evening will be partly cloudy, with more clouds developing after midnight.
