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.

The asteroid that struck Earth 66 million years ago, wiping out much of the planet's plant and animal life (most famously the dinosaurs), also triggered a worldwide tsunami with mile-high waves.
In 2019, the Hayabusa2 spacecraft collected samples from the asteroid Ryugu. Now, an analysis of these fragments has revealed Ryugu's history.
The James Webb Space Telescope and its older counterpart Hubble photographed the impact of NASA's asteroid-smashing DART probe into the space rock Dimorphos on Monday (Sept. 26).
More than four years after DART's collision with the asteroid Dimorphos, Europe's Hera mission will help validate the space rock deflection experiment.
Lunar glass reveals that large meteorite strikes on Earth, like the impact that killed the dinosaurs, were not isolated events.
NASA's DART mission didn't nudge its target asteroid toward Earth, but there could be other space rocks on a collision course with Earth.
Astronomers watched in awe as binary asteroid Didymos brightened up immediately after the impact of NASA's DART mission on Monday (Sept. 26).
Reference Didymos is a binary asteroid system that NASA's DART mission visited during the agency's first planetary defense mission.
Reference NASA's DART mission was the first to test asteroid deflection for planetary defense by smashing a spacecraft into an asteroid. Explore the mission here.
DART may have completed its journey, but the work is only just starting for scientists as they set about learning how much the asteroid Dimorphos was deflected by its impact.
It's rare for spacecraft mission personnel to cheer at the words "loss of signal," but tonight, that's exactly what happened.
For the first time in history, a spacecraft from Earth has crashed into an asteroid to test a way to save our planet from extinction.
It will take days to weeks for astronomers to confirm whether or not NASA's asteroid smasher DART changed the orbit of its target, asteroid Dimorphos.
NASA will slam the DART spacecraft into an asteroid for target practice to get ready for the next big hit, but don't worry: nothing big is set to come at us for the next 100 years.
The DART spacecraft's tiny companion is ready to photograph a brand-new impact site Monday night (Sept. 26).
