Dwarf+Planets




 * || Only two of the five dwarf planets have been observed enough to fit the definition of the dwarf planets.

A dwarf planet is a celestical body that (A) is in orbit around the sun (B) has sufficient mass for its self gravity to overcome ridged body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, (C) has not cleared the neighborhood around its orbit, and (D) it is not a satellite. ||

Dwarf planets​ - all of the objects that are not one of the eight dominat bodies.

The world was introduced to dwarf planets in 2006. The difference between dwarf planetsand regular planets is that all dwarf planets are identical and regular planets are not identical.There is oniy five dwarf planets now and astronomers say that the number of dwarf planets are expected to grow. They say there may be 200 or so dwarf planets along the distances of the Kuiper Belt they would be able to identify them if they are dwarf planets or not with a better telescope.

Makemake is the newest member to the family also known as 2005FY9. Makemakeis about two thirds the size of Pluto.



Eris was one of thfirst three objects classified as a dwarf planet. Same as Pluto and Ceres, Eris was first spotted in January 2005.

Ceres is known as a asteroid and a dwarf planet, same as Pluto and Eris it was discovered on January 1, 1801 by the Italian astronomer Giuseppe Piazzi. Ceres has a diameter of 605 miles. Ceres orbits the sun every 4.6 years and has 9 hour long days. It orbits between Mars and Jupiter.



Pluto is known as a frigid ball of ice and rock. It is also known as a planet, but it is the weirdest of all the planets. It was discovered in August 2006 by th International Astronomical Union, and still hasn't made one full orbit around the sun, at a speed of 4.9 miles per hour.

Sedna is also known as 2003VB12, it is also the farthest body known that orbits our sun, at 90 AU's away, more than three times as far as Pluto is away from the sun. Sedna is about 1800 km in diameter slightly smaller than Pluto. With how far it is from the sun it takes 10500 earth years to orbit the sun.​

Febuary 2005, Orcus was discovered then was also known as 2004DW. It was forgotten by the annoucement of Sedna. The name of Orcus came fromthe god of the underworld. Orcus' orbit takes 248 earth years to orbit the sun, and the size is just smaller than Pluto.

Quaoar was discovered in the Kuiper belt in June 2002 by Chad Trujillo and Mike Brown. It is also the largest object in the Kuiper belt. It has half the diameter of Pluto, and is about 1 billion miles away from the sun.

Varuna space astronomers also say that Varuna is the biggest object in the Kuiper Belt. When the International Astronomical Union 2006 draft proposal defined Varuna as a dwarf planet. Varuna's rotation takes 3.17 hours or 6.34 hours depending wether the light curve is single or double peaked, and it takes 284.65 earth years to orbit the sun.
