The asteroid known as 2018 VP1 is about the size of a refrigerator and its hurtling toward Earth at speeds over 24,000 mph. It will come closest to the planet on Nov. 2.
Scientists estimate there is a less than 1% chance it would actually strike the planet - and if it did, it would likely burn up in the atmosphere and not cause significant damage on the surface.
"It may buzz-cut Earth on Nov 2, the day before the Presidential Election," tweeted astronomer Neil deGrasse Tyson.
"It's not big enough to cause harm. So if the World ends in 2020, it won't be the fault of the Universe."
