This will be the second full moon in October 2020, making it a so-called rare “Blue Moon”. Not only has there not been a full moon on All Hallow’s Eve since 2001, there won’t be another one until 2039. And for the first time tonight’s Blue Moon will be visible to most of the world in 75 years.

You will also see a red object near the moon tonight: that’s Mars. Also happening on Saturday night: Asteroid 2020 UX3 will be whizzing by Earth at a speed of 36,000 miles per hour. But don’t worry – experts who track this sort of stuff say it won’t hit us. But there’s another asteroid (2018VP1) making a close pass by Earth on Election Day.

Spooked yet?
