Asteroid

Meteor showers are celestial events during which numerous meteors appear in the night sky, originating from what seems like a single location.

Scientists say the Iowa-sized object in the asteroid belt has a surface composition similar to Ceres.

Due to its size, the object will appear quite bright in the sky as it flies past Earth at speeds of around 25,000 miles per hour.

The space rock could measure up to 3,248 feet in diameter.

A study has reconstructed the immediate aftermath of the asteroid 66 million years ago to learn more about the impact of the momentous event.

The space rock will come within around 4.6 million miles of our planet, traveling at speeds of 10,400 miles per hour.

Asteroid 2019 OK is about 328 feet in diameter, traveling at almost 15 miles a second; if it hit, it would have struck with over 30 times the energy of Hiroshima.

All three of the space rocks are classified as Near-Earth Objects (NEOs)—a term which refers to any asteroid or comet whose orbit takes it within 121 million miles of the sun.

The Aorounga crater measures 7.8 miles in diameter and is thought to have been created by the fragment of an asteroid that struck Earth less than 345 million years ago.

The carvings were made on a strange formation within the crater known as the "Rain Snake" dyke.

Food, payment and logistics systems are connected. If one starts crashing, the chaos may cause other systems to crash, and before we know it we'll have massive shortages and conflicts.

The object will come within about 3 million miles of our planet.

Scientists have long been puzzled by the asymmetrical nature of the moon's two hemispheres.

The source of water on Earth and other planets like Mars is hotly debated in the planetary science community.

Apohis is set to whiz past Earth at a distance of 19,000 miles in 2029.

NASA asteroid hunter Amy Mainzer talks about how the space agency hopes to find potentially hazardous space rocks.

"I knew we were looking at something very rare," said one of the authors of a new study.

The asteroid is located around 214 million miles from the Sun.

The dinosaurs didn't have a chance.

The space rock is traveling at around 30,400 miles per hour.

The celestial event is caused by a stream of cosmic debris falling toward Earth at around 80,000 miles per hour.

Geminid meteor shower will peak on December 13 and 14.

The spacecraft will hopefully return to Earth in 2023 with space rock samples from the surface of the asteroid.

Researchers think the aerial explosion could have destroyed the city in an instant.

The space rock will barrel past Earth at 4 miles a second.

The research could help scientists understand natural disasters like landslides.

Scientists recently got a close look at the asteroid responsible for the Geminid meteor shower.

The comet was discovered hurtling through the solar system in 2017, but its origins have remained a mystery.

These ancient rocks are relics of the early solar system.

Astronomers have got an awful lot better at spotting nearby asteroids—but there's still a long way to go.
