Fridge-sized asteroid hit Earth two hours after it was discovered

An asteroid around the size of a refrigerator was spotted hours before it hit Earth's atmosphere, and while it wasn't dangerous, it marked the fifth time in history an asteroid was detected right before hitting our planet.

On March 11, astronomer Krisztian Sarneczky noticed an asteroid at the Piszkéstető Observatory in Hungary. Sarneczky reported it to the International Astronomical Union's Minor Planet Center, which confirmed it was the first time the asteroid had been observed.

Half-giraffe-sized asteroid hits Earth, according to the Daily Mail | Boing Boing

The space rock, named 2022 EB5, is believed to have mostly burnt up in our planet's atmosphere, but even if it had impacted the surface it would have done little to no damage because it was just 10ft (3 metres) wide, about half the size of a giraffe.

Some people in Iceland reported hearing a boom or seeing a flash of light around the time 2022 EB5 scooted across the sky at 11 miles per second (18.5 km/s) between Greenland and Norway.

Strange dwarf planet Ceres may have formed at the icy edges of the solar system, scientists ...

Ceres, the most dominant member of the asteroid belt , doesn't look like the other asteroids. Most notably, it has a lot of ammonia on its surface, which other asteroids tend to lack.

In a new paper, researchers propose a possible explanation for why Ceres is so different from its neighbors: Perhaps the dwarf planet began in an orbit beyond Saturn and, during a massive reshuffling of the outer planets, got planted into the asteroid belt, where it has remained to this ...

Asteroid that ended dinosaur age struck in spring 66 million years ago

After nearly 150 million years, the reign of the dinosaurs ended 66 million years ago with the crash of a six-mile-wide meteorite into Mexico's Yucatan Peninsula. Two recent studies have determined what time of year that collision occurred.

The impact created huge waves, called seiches, in the sea that covered the central part of North America at that time. About 13 minutes after the impact, a large wave carrying a huge amount of sediment struck an estuary in what is now North Dakota, at a site called Tanis.
