There has been recent talk of another planet after Pluto. Pluto however lost it's 'planet' status. This new heavenly body may or may not be considered a planet. Here's something you might find interesting.


Planetary scientists at the California Institute of Technology have discovered a new planet in the outskirts of the solar system. The object circles the sun every 288 years compared to Pluto's 248 years. It has a diameter of about 1250 km, just about half that of Pluto. Even so, it is larger than all of the objects in the inner asteroid belt combined and is the largest object in the solar system discovered since Pluto in 1930.

The new planet has provisionaly been named "Quaoar" (pronounced KWAH-o-ar) after the creation force of the Tongva tribe who were the original inhabitants of the Los Angeles basin, where the Caltech campus is located.

The most distant planet in our solar system is Neptune.
Pluto is a dwarf planet and we know of the dwarf planet Eris. Eris' orbit goes beyond Pluto's.

Here is a picture of it's orbit, en.wikipedia.org...:Eris_Orbit.svg/

Apparently there are several "planetoids" of pluto's size or less outside its orbit...

As Umbrax said, Neptune is the largest planet in our solar system...It is highly unlikely we will find a body of sufficient size outside Pluto's orbit in order to qualify it as a planet...

Peace

There is a class of oblects called 'Plutinos', of which Pluto is one of them.

Plutinos are 'Kuiper Belt Objects' whose orbits are 'trans-Neptunian', meaning that their orbits take them iside the orbit of Neptune. There was a time from 1979 to 1999 that Pluto was actually closer to the sun than Neptune was. This will happen again between the years 2227 and 2247. Other Plutinos include Orcus, Rhadamanthus, and Ixion.

Yes, Pluto was demoted from Planet to 'dwarf planet', but if you want to feel good about Pluto again, think of it this way: Pluto is one of the largest and closest "Kuiper Belt Objects", which makes it a very exciting and interesting heavenly body. Other Kuiper Belt objects are Eris (larger than Pluto), and Sedna (about 3/4 the size of Pluto.)

So don't feel bad that Pluto is no longer classified as a Planet. Pluto and other Kuiper Belt objects are definitely very interesting things...the stuff that made up the planets in our solar system is out there in the Kuiper Belt, and those objects remain largely unchanged since the solar system formed 4.5 billion years ago. The 'New Horizons" space probe which is now on its way to Pluto is going to continue on past Pluto to explore the Kuiper Belt.

Before the debacle over Pluto's planethood, several other planets in the same size range were discovered, including Sedna.

And Eris, which is larger than Pluto:

Ceres in the asteroid belt has been promoted to "dwarf planet."
