They're calling them "planetary embryos". Scientists believe that two asteroids might be fragments of long-lost "planetary embryos" from the early solar system. These embryos, somewhere between ...

In case there are no physical samples from the asteroids, which is often the case, scientists rely on the object's physical characteristics—including its reflectance and albedo, to understand ...

Astronomers Find the Smallest Asteroids Ever Detected in the Main Belt Dec. 9, 2024 — Astronomers have found a way to spot the smallest, 'decameter,' asteroids within the main asteroid belt.

In a recent study, scientists at the IBS Center for Climate Physics (ICCP) at Pusan National University in South Korea ...

One such origin is the Main Asteroid Belt, but it's not the only place where asteroids emerge. Each object is a special case, and scientists compare them with known meteorites. Of course, you need ...

One such origin is the Main Asteroid Belt, but it's not the only place where asteroids emerge ... including its reflectance and albedo. Those two properties can often tell you what part of ...

NASA has called in the James Webb Space Telescope to track asteroid 2024 YR4, a newly identified space rock with a 2.1% ...

Asteroid 2024 YR4 has a tiny chance of hitting Earth in 2032, but for now, you can watch it fly harmlessly through space in a short time-lapse video captured by the NASA-funded ATLAS telescope.

What is the 'alien' that has been found near the South Pole? NASA is keeping a close watch on three asteroids making near-Earth approaches today. One of them, named 2025 CF, will pass within just ...

The night sky will witness a celestial event soon. Two asteroids are set to pass Earth on 31 January. NASA’s Jet Propulsion Laboratory (JPL) is tracking their movement. Scientists confirm that ...

31, 2025. Credit: NASA Here are today's general risks from asteroids or comets both tiny and very large. Importantly, even relatively small rocks can still be threatening, as the surprise 56-foot ...
