The NASA researchers have now discovered that the Ceres has an ocean world.
There are five dwarf planets in the solar system. They are Pluto, Eris, Haumea, Makemake and Ceres. The NASA researchers have now discovered that the Ceres has an ocean world.
Highlights
Ceres is found between Mars and Jupiter. According to the research, Ceres looks to be a remnant ocean world. Also, Ceres has a brine reservoir that is located 40 km deep and is 100s of miles wide. This makes the dwarf planet water rich.
There are other moons and dwarf planets in the solar system where oceans exist. This includes moons of Jupiter and Saturn.
Hygiea
There are contradictions if Hygiea is a dwarf planet or an asteroid. According to the observations made under European Space Organization telescope SPHERE, Hygiea shall be considered as dwarf planet. This is because it satisfied the main four conditions of a dwarf planet set by International Astronomical Union
The body should orbit around the sun
It should not be a moon
It should not have cleared the neighbourhood around its orbit. This means that it is not a dominant body in its orbit around the sun. This is the main feature that makes the dwarf planet different from the planet.
It should have enough mass of gravity to pull it into a rough spherical shape.
Ceres Exploration
The Ceres was first spotted in 1801 by Giuseppe Piazzi. He assumed that Ceres was the missing planet between Jupiter and Mars. However, it was clarified as dwarf planet in 2006.
The Dawn Mission of NASA
The mission was launched in 2007. It orbited two Ceres and Vesta. In 2011 it became the first spacecraft to orbit Vesta. In 2015, it became the first spacecraft to orbit Ceres.
The data from the Dawn mission helped scientist to learn how planets grow and differentiate and where and when life could have formed in solar system.
