A dwarf planet is a celestial body orbiting the Sun that is massive enough to be rounded by its own gravity but has not cleared its neighbouring region of planetesimals and is not a satellite . Dwarf planets are planets tthat are considered to small to be considered a planet.

DEFINITION OF A PLANET “ A non-luminous celestial body larger than an asteroid or comet, illuminated by light from a star, such as the sun, around which it revolves.” (www.nasa.gov)
WHY PLUTO ISN’T ANYMORE CONSIDERED A PLANET? WHEN THEY DISCOVERED COMETS AND ASTEROIDS BIGGER THAN PLUTO THEY DECIDED THAT PLUTO WAS TO SMALL FOR BEING A PLANET.

PLUTO’S SIZE CHARON is the moon of Pluto and its half its size. PLUTO is the second largest dwarf planet. (after Eris) www.nasa.gov
PLUTO’S TEMPERATURE <ul><li>VERY COLD </li></ul>Freezing
PLUTO’S MATERIALS ICE ROCK METHANE GAS NITROGEN
PLUTO SPINS ON IT’S AXIS ONE DAY ON PLUTO = 6 EARTH DAYS.
PLUTO’S REVOLUTION AROUND THE SUN ONE REVOLUTION AROUND THE SUN = 248 EARTH YEARS.
