NASA is testing one technique it might use should a large asteroid threaten to collide with Earth. But just how high are the odds of such a dangerous space rock after all? You don't need to panic.
Asteroids are space rocks thought to be the remains left over from the formation of the solar system. They range in size from tiny (the size of a car or so) to truly giant, with at least one - Ceres - gaining dwarf planet status. In our solar system, billions of asteroids are in the asteroid belt, a region around the sun between the orbits of Mars and Jupiter. Others stray from this region, and can potentially post an impact threat to the Earth. At least one interstellar asteroid, called 'Oumuamua, has passed through our solar system.

Reference NASA’s Lucy mission is the first to visit the Trojan asteroids. Lucy will help answer questions about the formation of the solar system.
The DART spacecraft's camera will take its first photos eight days after launch, if all goes according to plan.
NASA has launched its DART mission to practice what the agency might do if planet Earth were threatened by a wayward asteroid.
The asteroid impact mission will launch no earlier than 10:20 p.m. PST on Tuesday, Nov. 23 (1:20 a.m. EST, or 0620 GMT on Nov. 24).
Sometimes, spacecraft must be destroyed anyway. And sometimes, it takes destroying a spacecraft to get the maximum science out of a mission.
NASA will launch a mission to crash into an asteroid (on purpose) overnight tonight and you can watch it live.
NASA's mission DART will test our ability to redirect an asteroid by quite literally crashing into it — but the spacecraft will also test a new type of propulsion system for the agency.
The first operation to ever collide a spacecraft with an asteroid is set to launch Wednesday (Nov. 24) and will see whether humans can deflect a potentially disastrous cosmic impact.
So you've heard that an asteroid could slam into Earth wreaking all sorts of havoc, but just how many space rocks out there threaten our planet?

The first teaser trailer for "Don't Look Up" has Jennifer Lawrence and Leonardo DiCaprio as astronomers hoping to warn Earth of a comet impact.
For billions of years, chaos and the laws of physics have governed our solar system; next year, humans will take the reins and purposefully, in a calculated strike, adjust the orbit of an asteroid.
Later this month, NASA will launch a mission to smack an asteroid into a new orbit to prepare for the possibility that an asteroid in the future might threaten Earth. But don't worry.
The Hera mission will follow NASA's DART asteroid-deflecting spacecraft to the binary space rock Didymos and detail the aftermath of DART's collision with the smaller of the two asteroids.
The small LICIACube spacecraft will watch its robotic colleague, NASA's DART mission, smash into an asteroid and sending the footage back to Earth.
