Objects in Our Universe

  What is the Dwarf Planet? According to the International Astronomical Union, the dwarf planets are the celestial bodies that orbits the sun, has not cleared the neighborhood around its orbit, has enough mass to assume a nearly round shape and is not a moon. The number of dwarf planets in our solar system is unknown. Now the question arises that why the Pluto is not a planet? The Pluto has enough mass to assume a nearly round shape, also orbits the sun but the Pluto has not cleared the neighborhood around its orbit. There are six known dwarf planets, the Pluto demoted as a Dwarf Planet, Eris the reason behind the demotion of the Pluto, Ceres the closest dwarf planet from the sun and from the Earth, the Makemake fourth dwarf planet, the Haumea fifth discovered dwarf planet and the Gonggong sixth dwarf planet with Chinese name. I explained the Pluto, Eris and Ceres in my previous article. 1] Makemake dwarf planet           ...

The Dwarf Planet Ceres.                   The dwarf planet Ceres is located in the main asteroid belt, between orbit of the planet Mars and the planet Jupiter. The Ceres is the largest object in the main asteroid belt. The Ceres is nothing but an asteroid but it is large enough to categorized as a dwarf planet. The Ceres has enough gravitational force to be round in shape. The Ceres is firstly classified as a planet. But when scientists found similar object near the Ceres. So, the Ceres is reclassified as an asteroid. So, the Ceres becomes largest asteroid in the main asteroid belt. As other objects were discovered in the neighborhood of the Ceres. Then it was realized that the Ceres must be classified as in a new category. So, the Ceres was given the designation under the modern system of minor planet. So, Ceres becomes the closest dwarf planet from the Earth. The dwarf planet Ceres named after the Roman goddess of corn and harvest...

Eris Dwarf Planet                 The Eris is second largest known dwarf planet and most massive dwarf planet in our solar system. The Eris is the ninth most massive known object that orbiting the sun and sixteenth most massive overall including all moon in our solar system. The Eris is largest object that has not been visited by any spacecraft. The scientists observed that the dwarf planet Eris has a one moon orbiting around, named as Dysnomia. The Eris most massive dwarf planet The dwarf planet Eris is named after the Greek goddess of discord. The Eris is once considered for the position of our solar system’s tenth planet. But Eris can not pass the new definition of planet which was set by the international Astronomical Union. But they demoted the planet Pluto to dwarf planet. The Eris is Trans Neptunian Object. The Eris orbiting the sun in a region of space known as the scattered disc. This scattered disc is...
