Dwarf planets are celestial bodies orbiting around the Sun that are not counted as planets because of their small size. Find questions about the different Dwarf Planets here.
A dwarf planet, as defined by the International Astronomical Union (IAU), is a celestial body orbiting the Sun that is massive enough to be rounded by its own gravity but which has not cleared its neighbouring region of planetesimals and is not a satellite of a planet. The term dwarf planet was ad…

No. Pluto is not a planet, at least not in the general sense of the word. The International Astronomical Union, the group who names objects in space, classified Pluto as a "dwarf planet" in 2006. Pluto orbits the sun in an elliptical orbit and actually travels inside the orbit of Neptune at times. P…

It has to do with the formation of the solar system. Since all of the matter that condensed into what makes the solar system bodies was spinning in the same direction while coming together, it would have taken a drastic event to cause one of the bodies to orbit in a different direction.

Pluto was considered a planet when it was discovered in 1930. However, as technology increased it became apparent that there were several other bodies in the same area as Pluto - called the Kuyper Belt - including one later named Eris that was slightly larger than Pluto. Now the IAU had a dilemma,…

Yes, there is a celestial object called Sedna (90377 Sedna), which is a dwarf planet candidate orbiting far beyond Neptune and Pluto. Its closest approach to the Sun is about 1.5 times the maximum for Pluto, with an extreme elliptical orbit varying from 76 AU to 975 AU. As the farthest identified ob…

The main difference is that a star emits its own energy, which it converts through nuclear fusion; a planet does not. As a result, you can expect a star to have a surface that's quite a bit hotter than that of a planet. What an object is depends, to a great extent, on its mass; objects up to about 1…
