Halley’s Comet is probably the world’s most famous comet. It returns to Earth’s vicinity about every 75-76 years, making it possible for a person to see it twice in their lifetime.
Comet C/2020 M3 will be closest to Earth this Saturday, although it won't be visible with the naked eye, you might be able to catch it with a telescope or binoculars. Plus, there's a new moon this weekend, so moonlight won't be a problem if you're out looking for this space visitor...
