2. DWARF PLANETS
• DWARF PLANETS ARE ROUND AND ORBIT THE SUN JUST LIKE THE EIGHT MAJOR
PLANETS. BUT UNLIKE PLANETS, DWARF PLANETS ARE NOT ABLE TO CLEAR
THEIR ORBITAL PATH SO THERE ARE NO SIMILAR OBJECTS AT ROUGHLY THE
SAME DISTANCE FROM THE SUN.
• THEY ARE SMALL. IN CONCLUSION THEY ARE SMALLER THAN OUR MOON, BUT
THEY ARE NOT MOONS.
• THE BEST DWARF PLANET KNOWN IS PLUTO.
