Every few years, an asteroid that’s about the size of a bus strikes Earth. These rocks are much smaller than the one that drove dinosaurs to extinction, but they can still have a significant impact.

Dwarf Lab releases the Dwarf Mini, a pocket-sized smartscope for deep-sky imaging, with 2MP RAW capture, IMX662 sensor and ...

The asteroid that extinguished the dinosaurs is estimated to have been about 10 kilometers across. That's about as wide as Brooklyn. Such a massive impactor is predicted to hit Earth rarely, once ...

The asteroids that are mostly likely to hit Earth aren't huge planet-killers, but smaller chunks of rock tens of meters wide — just big enough to wreak havoc on a city or a region. There are many more ...

The majority of the known asteroids orbit within the main asteroid belt located between Mars and Jupiter at an average distance from Earth of about 250 millions kilometers. Since the discovery of the ...
