Asteroid Impact Avoidance

NASA is bringing the world of planetary defense to the public with its new documentary, "Planetary Defenders."

New observations from the James Webb Space Telescope show that the potentially hazardous asteroid 2024 YR4 is a building-sized space rock

The instrument enclosure of NASA's Near-Earth Object Surveyor is prepared for critical environmental tests inside the historic Chamber A at the Space

On March 12, 2025, Hera -- ESA's first Space Safety mission -- came to within 5,000 km of the surface of Mars and 1,000 km of Deimos.

NASA said Wednesday that new data collected overnight cut the probability of asteroid 2024 YR4 hitting Earth to 1.5%. The chances of impact had been 3.1%.

A potentially hazardous asteroid is on its way to the planet, and many are growing concerned about it including China.

The head of planetary defense at the European Space Agency discusses 2024 YR4, an asteroid with a small chance of striking Earth eight years from now.

Ian Sample hears from Richard Binzel, a professor of planetary sciences at MIT and inventor of the Torino scale, which is used to categorise the threat posed by objects such as asteroids and comets

Astronomers track asteroid 2024 YR4, with a 1.9% chance of impacting Earth in 2032, but NASA said there's nothing to be worried about.

The asteroid is unlikely to be cause for concern, but its detection has triggered planetary defence response procedures for the first time

The enormous near-Earth asteroid (887) Alinda has made its closest approach to our planet in decades, and it's about to peak in brightness in a rare once-in-a-decade event. Here's how to watch it live this weekend.

These asteroids are as small as 10 m across, making them the smallest asteroids ever observed in the main asteroid belt.

A small asteroid burned up in Earth's atmosphere off the coast of California just hours after being discovered and before impact monitoring systems had registered its trajectory.

The European Space Agency's Hera mission is on its way toward Mars, where it will get a gravity assist before going on to its asteroid target.

The European Space Agency has given the go-ahead for initial work on a mission to visit an asteroid called (99942) Apophis. If approved at a key meeting next year, the robotic spacecraft, ...

The space agency defied incredible odds to get its asteroid-hunting OSIRIS-REx spacecraft off the ground. Since then, the mission has upended everything we know about our solar system.

A spacecraft has blasted off to investigate the scene of a cosmic crash

The European Space Agency is sending a probe to get a closer look at the asteroid Dimorphos, which had its orbit altered by NASA's DART mission in 2022
