An asteroid is on a collision course with Earth, possibly making impact in 2032. In the unlikely event that Asteroid 2024 YR does strike Earth, it would generate an explosion equal to nearly 8 million tons of TNT. That’s 500 times the power of the atomic bomb that was dropped on Hiroshima during WWII. But there’s no cause for alarm: Space agencies estimate there’s about a 2% chance of impact, and that number may go down.
