A popular myth suggests the asteroid belt was once a planet that broke apart. But in reality, the total mass of all asteroids in the belt is only about 4% of our Moon.

Asteroid 2024 YR4 has a 0.0017% chance of hitting Earth, but media reports too often ignore the unlikelihood of impact in reports of near-Earth asteroids, a Tucson astronomer says.

The asteroid, about a third of a mile wide at its equator, poses no immediate threat to our planet. But hundreds of years from now, there is a small chance that Bennu could slam into Earth.

After months of tracking and refining Asteroid 2024 YR4's orbit, NASA scientists were able to rule out an Earth strike. There's no real risk to the planet in seven years or afterward, according to ...

Looking at how the rock absorbed sunlight and emitted heat, astronomers found that it was rich in silicates. This indicated it likely originated in the solar system’s main asteroid belt between Mars ...

An enormous asteroid—big enough to leave a six-mile-wide crater and darken the world with dust if it hit Earth—will harmlessly zip by our planet on April 29. The object, called 1998 OR2, is at ...

Since the asteroid belt is past Mars, there's an average 25-minute communications delay in each direction, making manual control from Earth and its surrounding environs exceedingly tedious.

This indicated it likely originated in the solar system’s main asteroid belt between Mars and Jupiter and was pushed into its current near-Earth orbit by gravitational interactions with Jupiter.
