Valentine's Day 2046 could be a very memorable one

If you have already booked a dinner reservation with a significant other for Valentine's Day in 2046, you might want to rethink your plans, as NASA has now revealed that it believes the Earth could be at threat of getting hit by an asteroid on that date.

Quite a Valentine's gift indeed, but NASA has said that its calculations say that an asteroid around the size of an Olympic swimming pool could hit the planet. And could is the big word here, as NASA states that it should get as close as 1.1 million miles near to Earth, but as with any calculations when you're accounting for over 20 years worth of change, the asteroid's trajectory could see it on a collision course for our planet.

In fact the chances have been boiled down to a 1 in 560 impact chance on the Torino Impact Hazard Scale, with this being the only asteroid on NASA's radar to be rated this highly. For those wondering about what this scale accounts for in regular human talk, NASA says that an impact is "extremely unlikely" and "no cause for public concern".

Still, with the way the last few years have gone, an asteroid impact in 20 years doesn't seem too far-fetched.

Thanks, BBC.
