The AMAZING Solar System!
Today Our Solar System Consists of …
Our Sun! The Center of our Solar System!
Eight planets that orbit the sun
Three dwarf planets that also orbit the sun
Over 150 moons that orbit the planets
Countless asteroids, many in the asteroid belt
Icy comets in highly elliptical orbits
An “Astronomical Unit” is a convenient way to
measure distances in the solar system. It is the
average distance from the earth to the sun, about 150
million kilometers (93 million miles)
In 2006, the “International Astronomical Union” (IAU) met in Europe and created a new
class of heavenly body, the dwarf planet. It included three objects in this new category
Ceres, the largest asteroid in the asteroid belt
Pluto, traditionally the ninth planet
Eris, discovered in 2005 and is larger than Pluto
The “Revolution Period” is the time is takes for the object to orbit the sun.
