Super Worm Moon 2019: Asteroid heading to Earth during lunar event on first day of spring

The last two Supermoons appeared on the nights of February 19 and January 21.

A Supermoon describes a Full Moon or a New Moon nearing its closest orbital position to Earth – the perigee.

The Almanac explained: “The official astronomical name for a supermoon is ‘perigee full Moon’ or ‘perigee syzygy’.

“The word ‘perigee’ refers to the Moon’s closest point to Earth in its monthly orbit, and a ‘syzygy’ is when celestial bodies line up – as the Sun, Earth, and Moon do during a full Moon.

“The Moon has an oval or elliptical orbit, not a round one, which means that every night it’s either a bit closer or farther from the Earth than it was the night before.”
