The picture on the right shows the nine planets
that include Mercury, Venus, Earth, Mars, Jupiter, Saturn, Neptune, Uranus, and
Pluto. Some of the planets have moon that orbit the planets We live on spaceship
Earth, the third plant from the sun and has a Moon. Earth is the only habitual
planet in our solar system. In addition to planets with their moons, their
are asteroids and comets.
Most of the asteroids are located in a belt Mars and Jupiter.
Powerful telescope are need to see the asteroids. Several hundred thousand asteroids have
been discovered and thousands more are discovered each year. Asteroids, coming close to
Earth, are called near Earth objects. There are no known asteroids on a collision course
with the Earth.
Comets
are natural sources of antimatter or
mirror matter and average one kilometer in diameter. We are
able to see comets from the annihilation of matter and antimatter. Solar dust
particles blast antimatter off comet's nucleus to form the plasma coma and tails.
When sungrazer comets collide with Sun, the explosions are measured in
billions of megatons of TNT or enough energy to supplied the World's entire energy
needs for over 10,000 years.
The average comet's mass is over a billion tons
and could supply the entire World's energy needs for billions of years.
