The mission, called Ramses (Rapid Apophis Mission for Space Safety), will give a crucial window into how asteroids are affected by gravitational forces – in this case, the gravity of Earth.

Sue Nelson explores how asteroids can inform our understanding of the Earth's past – or threaten our future. Each year, according to Nasa, a chunk of rock the size of a car hurtles through space ...

An asteroid is a metallic or rocky body that orbits the Sun within the asteroid belt, a region of space between Mars and Jupiter. Asteroids are believed to be remnants of the early formation of ...

The calculations are made by Sentry, a highly automated collision monitoring computer system that scans the most up-to-date list of asteroids near Earth. The Torino Scale, which runs from 1 to 10 ...

Mar. 17, 2025 — New 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 and spin ...

And two airplane-sized asteroids—"2025 DT4" and "2025 DG3," each measuring around 100 feet across—are expected to make a close approach later today, according to CNEOS. A stock image showing ...

In short, asteroid 2024 YR4 went from breaking records for known threatening asteroids to being a near-zero threat. At some point in the near future, this risk may be out of date. The rock is 130 ...

More than 38,000 asteroids are known to be in Earth's vicinity, including 973 "planet killers" of more than half a mile in diameter. Most pose no risk. But NASA estimates that only about 43% of ...

Representative image created using AI. This weekend, two asteroids – 2025 DE5 and 2025 DB22 – will make close approaches to Earth, travelling at alarming speeds. While they are not expected to hit our ...

There are countless numbers of asteroids and an unknown number of comets throughout our solar system. Most of these objects date back to the very beginnings of our solar system, around 4.5 billion ...

This makes it ideal to track faint objects such as 2024 YR4 and other potentially dangerous asteroids. This is a sequence of observations of the Near Earth Asteroid 2024 YR4 carried out with ESO’s ...

For a brief window, Asteroid 2024 YR4 looked like a planetary hazard in the making. At up to 90 meters (295 feet) in diameter, it was described as a potential “city killer.” On its estimated ...
