At around 7pm AEST on Monday night, the sky will light up as the moon's orbit brings it the closest it's been to earth since 1948. The moon will appear brighter and larger than most living people have ever seen it - and it won't come this close to earth again until 2034.

Supermoons themselves aren't rare occurrences, but this one's particularly special because a) it's coming so close to earth, making it appear even bigger than usual, and b) it will be a full moon.

News.com.au reports that over 60,000 people are planning to flock to Bronte Beach to watch the Supermoon's ascent over the ocean on Monday night. Mark your diaries, and cancel your dinner plans - or better yet, plan a moonlit picnic.
