WHAT ELSE IS IN OUR UNIVERSE?
We know that comets are lumps of ice and dust that periodically come into the
center of the solarsystem from somewhere in its outer reaches, and that some comets make repeated
trips. When comets get close enough to the Sun, heat makes them start to evaporate. Jets of gas
and dust form long tails that we can see from Earth. These tails can sometimes be millions of
miles long.
An asteroid is just like any of the bodies revolving around the Sun; mini-planets if you like.
They are probably made up of the same stuff of most other bodies in our solar system,
just that they are much smaller. Some have diameters of up to 500 miles and then some only 100
meters; the largest asteroids are called planetoids.
A meteorite is a rock that was formed elsewhere in the Solar System, was captured by Earth's
gravitational field, and fell to Earth as a solid object. A meteoroid is what we call the rock
before it strikes the Earth. A meteor is visible streak of light that occurs as the rock passes
through the atmosphere and exterior of the rock is heated to incandescence. (What to call it at
the moment it hits the ground is a matter of debate. Some people say "meteorite impact," others
say "meteoroid impact.") Most (~99.8%) meteorites are pieces of asteroids. A few rare meteorites
come from the Moon and Mars.
To date there has been little evidence of wether extra terrestrials or "aliens" actually exist or
not. Government activity such as AREA 51 suggest they are trying to cover up such existances from
the public. The famous Roswell crash has been examined by thousands as to wether or not it was
actually real or it was just a well planned hoax. Most people see aliens as being little green
men with big black eyes but in reality any sign of life outside of eaths atmosphere is classed
as an "alien" wether it be a single cell on a planet or as recently found proof of water on Mars.
