In its preliminary data release, taken from just seven nights of observations, the powerful Vera C. Rubin Observatory has ...

For large Main Belt asteroids, that break-apart point was set at a spin period of about 2.2 hours – a hard limit suggested by ...

Astronomers say the Vera C. Rubin Observatory has detected an asteroid that spins faster than other space rocks of its size.

But Rubin’s early data is confounding. Among the newly discovered asteroids, researchers identified 76 with reliable spin ...

Astronomers analyzing data from Vera C. Rubin Observatory have discovered the fastest-ever spinning asteroid with a diameter ...

An artist’s illustration depicts 2025 MN45—the fastest-rotating asteroid with a diameter over 500 meters that scientists have ...

Among the first finds from the Vera C. Rubin Observatory, the discovery hints at a population of exceptionally strong ...

2025 MN45 isn't the overall spin-rate record holder. Astronomers have found a number of small asteroids — those just a few ...

At 710 meters (just under half a mile) wide, this space rock sets a record for how fast it spins on its axis: about one ...

With a diameter of around 2,300 feet, the newly-detected asteroid completes a full rotation in just under two minutes.

Grab-and-go missions to asteroids have provided some of the most scientifically valuable samples since the Apollo ...
