(WRIC-TV) As the eclipse plunges the world into darkness on Friday, two other spectacular celestial events will be taking place, too: a supermoon and the spring equinox.

A supermoon, or perigee moon, happens when the full or new moon does its closest fly-by of the Earth, making it look bigger than it normally does, The Independent reports.

The spring equinox is the time of year when day and night are of equal duration. It marks the in-between point of the year’s shortest and longest days.

The solar eclipse is a phenomenon that happens when the sun and the moon line up, so that the moon obscures the look of the sun. While the eclipse won’t be effected by the other two events, the three events are rare even when occurring individually.

Supermoon

There are usually between three and six supermoons per year. There are six supposedly happening in 2015, two of which have already occurred. The next will take place on March 20, the day of the eclipse. The rest come in August, September and October.

Eclipses can only happen at a new moon, when the moon appears to be entirely shadowed, according to The Independent.
