Yes Plutos status as a planet has been continually defended by the International Astronomical Union.

. Is Pluto a Planet. The debate rages on. Whats a Planet Anyway.

On Monday May 7 The Washington Post published a Perspectives piece the two scientists wrote titled Yes Pluto Is a Planet. Soon after Pluto was discovered in 1930 it was designated a planet the ninth in our solar system. There are no longer nine planets in orbit around the Sun but rather there are now eight.

The theory behind this definition is that once an object is large enough it would sweep up smaller bodies in its vicinity leaving its orbit empty except for itself few transient interlopers comets. It also was considered the most recently discovered planet having been found in 1930. Fiercely debated by the members of the union the resolution that was passed officially defined the term planet.

By Kenneth Chang Jan. No Pluto has more in common with the. A dwarf planet is round and orbits the sun just like the eight major planets of the solar system.

On average Pluto is a distance of 395 astronomical units or AU from the sun. Thus Pluto went from being the ninth planet in our solar system to one of five dwarf planets with the IAU having said at the time that Pluto is. The main event of the 2006 General Assembly of the IAU the proposal that would come to demote Pluto was a defining moment for the rest of the solar system as well.

Pluto large distant member of the solar system that formerly was regarded as the outermost and smallest planet. However after 2006 models of the solar system became somewhat different. Pluto according to this criterion is not a planet because its mass is smaller than the estimated total mass of all other Kuiper Belt Objects.

More than 15 years after Pluto was demoted to dwarf planet the debate even among scientists continues. Mercury was the closest planet to the Sun and Pluto was the furthest planet from the Sun. These are the facts since they are the numbers and math of the astronomical object that is Pluto.

A dwarf planet also is much smaller than a planet but it is not a moon because a dwarf planet orbits the sun. Why is Pluto no longer a planet. After 2006 Pluto was no longer considered a planet by the astronomical community.

In August 2006 the International Astronomical Union IAU the organization charged by the scientific community with classifying astronomical objects voted to. So it is easier to call Pluto a planet or even an asteroid than to call it a rocky giant that orbits the sun. Pluto is a rocky object in space that orbits our sun and has a radius of 1153 km and a mass of 13 x 10 22 kg.

A group of researchers say Pluto was unfairly maligned by a decision to relegate it to dwarf planet status and that we should consider our solar system to have more than. After Pluto was discovered many astronomers presumed it to have been responsible for the perturbations they have observed in Neptunes orbit. Although its size and elliptical orbit do differ from those of the solar system s other planets these criteria are arbitrary traits that do not discount its status as a planet.
