NASA is monitoring an asteroid that could collide with Earth on Valentine's Day in 2046

Out of the millions of asteroids in our solar system, there's a very small fraction known to potentially impact Earth. But scientists found a new one just two weeks ago that so far seems to pose one of the greatest risks of them all. 

The asteroid, known as 2023 DW, was only first discovered on Feb. 26, according to the European Space Agency. It's now been added to the agency's Risk List, a catalog of space objects that could potentially have some kind of impact on Earth, and because of what scientists have so far seen – it's ranking on the list is currently at No. 1.

But don't worry, that doesn't mean catastrophic damage is imminent.
