If some asteroid big enough to do damage has us in its crosshairs, we hope we’ll know about it as soon as we can, giving us enough time, perhaps, to do something about it.

This year, the alert system for defending the planet against incoming space rocks was activated for the first time. It won’t be the last ...

The deep space asteroid that recently made headlines for its potential to collide with Earth received its own photoshoot courtesy of NASA’s James Webb Space Telescope.

Observations from the European Southern Observatory's Very Large Telescope helped show that the expected trajectory of asteroid 2024 YR4 poses nearly zero risk of impacting Earth in 2032.

The chances of asteroid 2024 YR4’s odds of colliding with Earth in 2032 have dropped to nearly zero, thanks to new observations of the space rock.

A Chilean space telescope has captured striking images of YR4 2024, the “city-killer” asteroid that’s potentially on a collision course with Earth.

Astronomers have captured a new image of the asteroid 2024 YR4, which now has a 1 in 48 chance of hitting Earth in 2032.

A dive into probabilities, asteroid impact modeling, and what sort of damage an approximately 180-foot asteroid could cause on Earth.

Asteroid 2024 YR4, which was recently spotted in the cosmos with a non-zero chance of hitting Earth in the coming years, may have caused some alarm.

Named 2024 YR4, the asteroid is estimated to be between 40 m and 100 m wide and is projected to come close to Earth in December 2032.

New close-up images reveal the surprising snowman shape of "potentially hazardous" asteroid 2024 ON, which tumbled safely past our planet on Sept. 17.
