Retired Canadian astronaut Chris Hadfield compared Asteroid 2024 YR4 to 'a bullet zeroing in on Earth from deep space' Asteroid has a 2.3 percent chance of hitting Earth on December 22, 2032 .
If this space rock were to hit Earth , it would create a blast equivalent to detonating 7.7 megatons of TNT and leave a 3,000-foot -wide crater in the ground.
It's about 500 times more powerful than the biggest bomb we exploded during WWII .
If astronomers determine that 2024 YR4 poses a very likely threat to Earth , humanity may still be able to save the planet.
In 2021 , NASA launched the Double Asteroid Redirection Test (DART) mission, which collided a spacecraft with the asteroid Dimorphos and successfully altered its orbit in September 2022 .
This was a test of the kinetic impactor technique, which space agencies could one day use to deflect an asteroid away from Earth .
