Surprise ‘city-killer’ asteroid almost hit Earth before whizzing by
A “city-killer” asteroid whizzed by Earth on Thursday, startling astronomers who didn’t pick up the rock’s trajectory until days before it passed the planet, according to a report.
NASA to test asteroid defenses by slamming spacecraft into space rock
If Earth were ever to be threatened by a large space rock — and it definitely will be at some point in the future — humanity is going to need to have a plan.
Massive asteroid to fly close to Earth in a decade's time
A massive asteroid will be visible to the naked eye when it passes close to Earth within the same distance as a spacecraft that orbits the planet, according to NASA.
NASA chief warns major asteroid could crash into Earth in our lifetime
NASA administrator, Jim Bridenstine, believes the prospect of a killer asteroid colliding with Earth isn't something reserved for science fiction films.
Japan creates first artificial crater on asteroid
Japanese scientists succeeded in creating what they called the first-ever artificial crater on an asteroid, a step toward shedding light on how the Solar System evolved, the country's space agency said on Thursday.
Japan space probe drops explosive on asteroid to make crater
Japan’s space agency said its Hayabusa2 spacecraft released an explosive onto an asteroid to make a crater on its surface and collect underground samples to find possible clues to the origin of the solar system.
Japan probe Hayabusa2 lands on distant asteroid
A Japanese probe sent to collect samples from an asteroid 300 million kilometers away for clues about the origin of life and the Solar System landed successfully on Friday, scientists said.
Were dinosaurs killed off by asteroid or volcanoes? It's complicated
Every school child knows the dinosaurs were killed off by an asteroid smashing into the Earth some 66 million years ago.
NASA probe finds signs of water on nearby asteroid Bennu
NASA’s OSIRIS-REx spacecraft discovered ingredients for water on a relatively nearby skyscraper-sized asteroid, a rocky acorn-shaped object that may hold clues to the origins of life on Earth, scientists said on Monday.
360-foot-wide monster asteroid on 'Earth approach' tomorrow: NASA warns
An enormous asteroid large enough to wipe out an entire city will zip past the planet tomorrow in the afternoon, space agency NASA warned.
NASA deep space probe reaches asteroid deemed potential Earth threat
NASA’s deep space explorer Osiris-Rex flew on Monday to within a dozen miles of its destination, a skyscraper-sized asteroid believed to hold organic compounds fundamental to life as well as the potential to collide with Earth in about 150 years.
NASA's Dawn asteroid mission ends as fuel runs out
Dawn, a NASA spacecraft that launched 11 years ago and studied two of the largest objects in the asteroid belt, ended its mission after running out of fuel, officials said Thursday.
Asteroid mining might actually be better for the environment
For a certain kind of investor, asteroid mining is a path to untold riches. Astronomers have long known that asteroids are rich in otherwise scarce resources such as platinum and water. So an obvious idea is to mine this stuff and return it to Earth — or, in the case of water, to a moon base or Earth-orbiting space station.
Touchdown! Japan space probe lands new robot on asteroid
A Japanese probe landed a new observation robot on an asteroid on Wednesday as it pursues a mission to shed light on the origins of the solar system.
Some of our system's youngest orbiting asteroids discovered in asteroid belt
Brazilian scientists have identified four new families of extremely young asteroids, taking the total number to 13.
