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.

China aims to launch a bold sample-return mission just three years from now, according to the nation's state-run Xinhua news agency.
An asteroid the size of a house gave Earth a close shave today (April 18), passing nearer to our planet than any other space rock will for the rest of this year — that is, as far as we know.
Fortunately, we're getting to the point where we can see potentially hazardous objects coming — and maybe even do something about it.
If the idea of an asteroid slamming into Earth keeps you up at night, spare a thought for a mission called NEOWISE, which reincarnated a former astrophysics spacecraft to hunt for nearby space rocks.

Europe's next asteroid mission, which could launch in 2023, will rely on the same kind of navigation technology as self-driving cars.
Japan's Hayabusa2 spacecraft slammed a copper cannonball into the asteroid Ryugu last night (April 4), in an effort to blast out a crater.
Japan's Hayabusa2 probe deployed a heavy copper plate toward the asteroid Ryugu last night (April 4), in an effort to create an artificial crater.
There are two rocket launches, a spacecraft docking, a lunar orbit arrival and an asteroid crash scheduled on Thursday (April 4). Here's how to watch live.
Most rocky bodies in the solar system bear the scars of past impacts, but only rarely can scientists watch those impacts occur in real time — and they're about to get just such a chance.
Two long, narrow tails of material are streaming from a 2.5-mile-wide (4 kilometers) rock in the main asteroid belt between Mars and Jupiter, a new study reports.

NASA is considering funding a mission that would send a satellite the size of a mini-fridge to the asteroid belt to examine an unexplored world: a massive asteroid scientists call Pallas.
If you want to use a nuclear weapon to save the world from an asteroid, don't try to do it the way Bruce Willis did, NASA's planetary defense office would like to remind you.
The near-Earth asteroid Bennu is one of just a dozen or so known 'active asteroids,' newly announced observations from NASA's OSIRIS-REx spacecraft reveal.
