City lights of Malaysia and Indonesia light up the Earth beneath a blanket of blue and orange airglow while boat lights glow in the Bay of Bengal in this nighttime view of Earth from space.
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.

Snatching a piece of asteroid Bennu was supposed to be — well, not easy, but certainly manageable: scope out the space rock, find some flat spots, swoop down at one, come back home.
A large and "potentially hazardous" asteroid is poised to fly by Earth next month, but don't worry — it poses no threat to Earth.
A cannonball that a Japanese spacecraft fired at an asteroid is shedding light on the most common type of asteroid in the solar system, a new study reports.
The rocky object that spawned the asteroid Ryugu may have been extraordinarily porous, a new study finds.
Astronomers discovered a 'minimoon' that's been orbiting Earth for about three years, and may soon leave our planet's orbit.
If a giant object looks like it's going to slam into Earth, humanity has a few options. A new guide could help NASA decide which one is best.
One of the most pressing problems when it comes to keeping our planet safe from space threats is data, which sounds so simple to address. It's not.
Excluding Mercury, this newly discovered asteroid has the smallest known aphelion distance in our entire solar system.
A black hole was photographed, the farthest flyby was completed, and a beloved rover was proclaimed dead. Follow us through the highs and lows of 2019 space science.
As the 2010s come to a close, it's time to revisit how some of the biggest space science stories shaped the decade.
For the first time, astronomers have gotten an up-close view of eruptions from an asteroid, shedding light on what might drive such explosions.
