In December 2024, astronomers in Chile spotted a new asteroid streaking through the sky, which they named 2024 YR4. What’s significant about this 100m-wide space rock is that it has a small chance of ...

Chances an asteroid may hit Earth in 2032 dropped to near zero, astronomers say. Here's what to know about 2024 YR4.

The 700–1,300 feet-wide space rock deformed rocks more than six miles from the impact site when it hit 600 million years ago.

In addition, the shape of the asteroid, and its albedo—which measures how reflective the asteroid is—is still highly uncertain, further complicating the prediction of its future path.

A weak magnetic field likely attracted matter inward, contributing to the formation of the outer planetary bodies, from ...

In 2021, a team led by Dr Gary Kinsland of the University of Louisiana at Lafayette found evidence that the impact and ...

Donaldjohanson formed about 150 million years ago when a much larger asteroid broke apart. Since then, its orbit and spin ...

During next month's flyby, Lucy will collect data on the asteroid's shape, surface geology and cratering history. The data Lucy will gather from Donaldjohanson is especially important because that ...

New Southwest Research Institute-led modeling indicates the main belt asteroid (52246) Donaldjohanson may have formed about 150 million years ago when a larger parent asteroid broke apart; its orbit ...

Donaldjohanson (DJ), which is about to be studied by NASA’s Lucy spacecraft in an upcoming flyby on April 20, 2025? This | ...
