Ceres now has the status of an “ocean world”.

Ceres has been named the "Ocean world  " by researchers,which lies in the asteroid belt between Mars and Jupiter and is also the largest object in that belt. New series of paper has been released by Nature Astronomy, Nature Communications and Nature Geoscience.

About Ceres

Ceres is an dwarf planet locates between Mars and Jupiter, is a mysterious and exotic world, with its complicated history and recent geologic activity.

The dwarf planet was first spotted by Giuseppe Piazzi in 1801. Piazzi tracks Ceres for 41 days and then he fell ill. Ceres moved into the halo of the Sun, leaving other astronomers without the ability to confirm the discovery.

Named in honor of the Roman Goddess of corn and harvests from who we derive the word cereal. It was classified as a dwarf planet in 2006 and is the first dwarf planet to be orbited by a spacecraft.

What is Dwarf planet ?

It's revolves around sun but it does not clear other objects from its path. It's size is very small.

There five dwarf planet in our solar system.

The most famous is Pluto, downgraded from the status of a planet in 2006. The other four are Eris, Makemake, Haumea and Ceres. The sixth claimant for a dwarf planet is Hygiea, which so far has been taken to be an asteroid.

There are four main criteria to be dwarf planet.

1. The body orbits around the Sun
2. It is not a moon
3. Has not cleared the neighbourhood around its orbit.
4. enough mass for its gravity to pull it into a roughly spherical shape.

Researcher on Ceres

Scientists are interested in the dwarf planet because it hosts the possibility of having water here. Therefore, scientists look for signs of life on Ceres.

By the time Dawn ended its mission in October 2018,the orbiter had dipped to less than 22 miles (35 kilometers) above the surface, revealing crisp details of the mysterious bright regions Ceres had become known for.

“Scientists had figured out that the bright areas were deposits made mostly of sodium carbonate — a compound of sodium, carbon, and oxygen. They likely came from a liquid that percolated up to the surface and evaporated, leaving behind a highly reflective salt crust. But what they hadn’t yet determined was where that liquid came from,” NASA researchers describe.

Now analysing the data which was collected at the end of the Mission, scientists have determined that ceres has a brine reservior located about 40 km deep and which is hundreds of miles wide, making the dwarf planet, "water rich".
