Astronomers have created a 3D representation of asteroid 2024 YR4.

NASA has selected eight participating scientists to join its Lucy mission to the Jupiter Trojan asteroids. These asteroids are remnants of our early

NASA has been changing the odds of asteroid 2024 YR4 hitting Earth in recent days, but the latest shift significantly downgrades the asteroid's threat level and makes a moon strike more likely.

The Geminid meteor shower this year is set to peak at almost the same time as December's full moon, which could make for challenging viewing conditions.

Phaethon is a weird asteroid that behaves like a comet. It's also responsible for the Geminid meteor shower. Find out how it does so, here. The post How asteroid Phaethon can spawn the Geminid meteors first appeared on EarthSky.

No probe has ever gotten a good look at the heliosphere from the outside or properly sampled the local interstellar medium.

Although it is still more than 18 months from its closest approach to Earth and the sun, comet Tsuchinshan-ATLAS already has social media buzzing, with...

Quirks of orbital mechanics make a cadre of sun-orbiting asteroids appear to be moons of Earth

Japan's Hayabusa2 spacecraft will zoom past a small near-Earth asteroid in 2026 as part of its extended mission — and you could help name the space rock.

The slowly spinning asteroid recently made a close approach to Earth.

The comet-like asteroid Phaethon likely lobbed thousands of rocky fragments toward Earth while rapidly spinning around the sun 18,000 years ago, new research suggests ― and it may fling some more soon.

It's finally time to look inside the sample-return capsule from NASA's OSIRIS-REx mission. Scientists were locked out of the container for months due to a technical malfunction.

The former OSIRIS-REx spacecraft sets off on a journey to study asteroid Apophis and take advantage of the asteroid's 2029 flyby of Earth, the likes of which hasn't happened since the dawn of recorded history.

Betelgeuse, one of the most recognizable stars in the night sky, will disappear for several seconds in a rare asteroid occultation on the evening of Dec. 11.

NASA's OSIRIS-REx recently dropped off a sample from asteroid Bennu, and now it will continue on to a new target: asteroid Apophis.

Astronomers show how a 50-meter space rock orbiting near Earth isn't a typical asteroid: It probably blasted off the moon millions of years ago.

The Asteroid Smoothie Shack was the only smoothie shop on the tiny planetoid NX-42789. Business was slow out here on the frozen edge of the solar system. Some days only a handful of customers stopp…

A NASA mission called Psyche is about to launch on a mission out to an unusual asteroid that's scientists believe is largely composed of metal.

Planet Earth is about to receive a special delivery — the biggest sample yet from an asteroid.

This algorithm, known as HelioLinc3D, was designed to uncover near-Earth asteroids.
