This is an impression of the largest asteroid, Ceres, now also formally designated a dwarf planet. Nobody has ever seen Ceres up close, but astronomers know that it is spherical (diameter about 1000 km) because of its mass. So I had free reign here t...

Binary Asteroid 90 Antiope
This is an impression of the binary asteroid 90 Antiope, which orbits in the main part of the outer asteroid belt. Each asteroid is about 86 km across, orbiting its partner from a distance of 170 km and with a period of 16.5 hours. Binary asteroids a...

High above the Earth, an asteroid a few kilometres across enters our planet's atmosphere at a speed of several kilometres per second. At that velocity, it is only a matter of seconds before the asteroid smashes into the surface, vaporising both itsel...
