Reuters The largest object in the asteroid belt between the orbits of Mars and Jupiter is Ceres. It was the first asteroid discovered in 1801 and was originally deemed a planet.

The largest known asteroid could contain more fresh water thanEarth and looks like our planet in other ways, according to a new study thatfurther blurs the line between planets and large space rocks.

A trip to Ceres, the largest asteroid and nearest dwarf planet, is no harder than a trip to Mars, researchers say.

Over the next few weeks, Ceres, the first asteroid discovered, passes in front of the bright Hyades star cluster, making it easy to find in a small telescope or pair of binoculars.

Ceres' location in the asteroid belt is intriguing because the dwarf planet is so much bigger and rounder than its companions. Even the 330-mile-wide (530 km) Vesta is irregularly shaped.

Asteroids might look dry and barren, but the Solar System’s biggest asteroid — Ceres — is chock full of water, NASA’s Dawn spacecraft has found. “It’s just oozing,” says Thomas ...

The largest asteroid in the solar system seems to have a salty ocean of water sitting deep beneath its surface.
