Asteroids

Asteroid Day is an annual celebration of asteroid science, and a reminder of how important it is to study these potentially dangerous objects. Here's how you can celebrate this year.

A house-size asteroid zoomed past Earth on June 25 at a staggering 2,000 mph and the Virtual Telescope Project was able to image the near-Earth object in real time.

A small asteroid the size of a three-story building will pass between Earth and the moon on Sunday (June 25), and you can watch the encounter live thanks to a free telescope livestream.

Tiny salt grains discovered in samples returned by the Hayabusa mission could indicate that the largest population of space rocks in the solar system is more watery than previously thought.

NASA's Psyche asteroid mission is on track to hit its new launch target of October 2023, a year later than originally planned, an independent review has found.

The European Space Agency (ESA) has designed a tiny mobile phone-sized probe that could become the world's first to measure the gravity on the surface of an asteroid.

The United Arab Emirates just provided new details about its planned asteroid mission, which will visit seven different space rocks — and land on one of them.

NASA's Lucy spacecraft has altered its course ahead of visiting its first asteroid target in Nov. 2023 on its way to become the first probe to visit the Trojan asteroids that orbit Jupiter.

Earth probably won't get hit by an asteroid at least 0.6 miles (1 kilometers) wide in the next 1,000 years, a new study finds.

The United Arab Emirates is targeting seven different space rocks with its ambitious mission to the main asteroid belt.

The first asteroid belt ever found outside the solar system is more complex than expected, new observations by the James Webb Space Telescope reveal.

Skywatchers will get an excellent opportunity to spot the 124-mile-wide asteroid Iris 7 as it reaches opposition on April 30 as the main-belt object also makes its closest approach to Earth.

Astronomers observing the strange "rock comet" hybrid Phaethon as it passed the sun have found a surprise that could upend 14 years of thinking about the weird asteroid.

The U.S. government has published an updated action plan for how to deal with potentially dangerous asteroids.

NASA's LUCY asteroid-hopping mission has for the first time spotted four of its asteroid targets which it will visit from 2027 onwards and send those images back to Earth.

Scientists have observed that some of Neptune's Trojan asteroids are deep red, possibly revealing what asteroids may have been like in the early days of the solar system.

The Apophis asteroid, recently cleared of imminent wrongdoing to Earth, already has one spacecraft visitor expected. NASA wants industry to send more.

A newfound asteroid called 2023 FW13 has been Earth's companion for centuries, astronomers say.

Observations by NASA's DART spacecraft suggest that the asteroid Dimorphos formed from material flung into space by its spinning asteroid partner, Didymos.

The potentially hazardous asteroid 2023 FM is larger than a 40-story building and will zoom within 7.5 lunar distances from Earth on Thursday, April 6, according to NASA.
