What is Asteroid Belt? | Main Asteroid Belt

Asteroid Belt In 1596, Johannes Kepler analysing data of Tycho Brahe’s, Kepler thought that there was too large gap between the orbits of planet Mars and Jupiter . According to Titius-Bode Law an apparent pattern in the layout of the planets, one planet is missing between the orbits of Mars and Jupiter. In 1781, the William Herschel discovered the planet Uranus . The planet’s orbit matched the Titius-Bode Law almost perfectly. In January 1, 1801, Chair of astronomy at the University of Palermo, found a tiny moving object in an orbit which is exactly predicted by the pattern. This object is the Ceres. The Ceres is the biggest asteroid in the main asteroid belt which was categorized as “Dwarf Planet”. The Heinrich Olbers found a second in the same region where the Ceres was found, Pallas. After the further investigation, the astronomer discovered two new objects in the same region named as Juno and Vesta. These four asteroids Ceres, Pallas, Juno and Vesta are half the

The Objects waiting to become a Dwarf Planet | Quaoar, Orcus, Sedna

Quaoar The Quaoar is a body that lies beyond the orbit of Pluto. Quaoar is one of the Kuiper belt object. Quaoar is massive enough to be considered as a dwarf planet, but it has not been classified as such yet. The Quaoar is discovered in 2020 by the American scientists Mike Brown and Chadwick Trujillo of the California institute of Technology at the Palomar Observatory in California. The Quaoar name is given after a creation god of the Native American Tongva Tribe. In 2007, the American astronomer Brown found the tiny moon around the Quaoar, Weywot. The name is given after the sky god, the son of Quaoar. The Quaoar The scientists believed that the Quaoar may be red in colour and coated with water ice. In the distant past of Quaoar, it had an atmosphere with nitrogen, methane and carbon monoxide. Because of low gravity of Quaoar, some of these molecules bled away into space but methane stayed. The solar radiation gradually formed hydrogen chins out o

Dwarf Planets in our solar system | Makemake, Haumea, Gonggong

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 Makemake is the second brightest object in the Kui

Ceres Dwarf Planet | The Embroynic Planet Ceres in Our Solar System

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 harvests. The closest dwarf planet from Earth, Ceres. Compo

The Eris dwarf planet facts | The Massive Dwarf Planet

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 just beyond the Kuiper belt. What is Dwarf Planet Eris?

The Sideways dwarf planet | The Pluto

The Pluto is the largest kuiper belt object. When the Pluto was discovered in 1930, the Pluto is declared as a ninth planet from our sun. But in 2006, the International Astronomical Union (IAU) defines the definition about the planate. And so, the Pluto is reclassified as a dwarf planet. So now the Neptune is the farthest planet from the sun. So, the temperature on the Pluto is -375 o to -400 o Fahrenheit or -226 o C to -240 o C. The Pluto named after the roman god of underworld. The Pluto’s rotation axis is tilted about 120 0 . So, as like the Uranus, the Pluto also rotates on its sides. The Dwarf Planet Pluto The Pluto is ninth largest known object which is directly orbiting the sun. Pluto’s orbit is moderately inclined relative to the solar system’s plane over 17 0 . Even the Pluto is a dwarf planet, it has five moons orbiting around. The one of moon of Pluto, charon is hydrostatic equilibrium with Pluto. This means that the moon charon and Plut
