what are asteroids asteroids the
celestial bodies that orbit around the
Sun the word asteroid means star like
and is derived from the Greek word a
star meaning star and oil meaning shapes
they are believed to be remnants of the
humongous cloud of dust and gases that
form the Sun and planets over four
billion years ago most of them lie in a
single belt between the orbits of Mars
and Jupiter sometimes changes in
gravitational slows and other forces in
space caused them to get dislodged from
their orbit and move away from the main
belt it is believed that a giant
asteroid crashed into the earth millions
of years ago causing such extreme
changes in weather
and the extinction of dinosaurs
scientists believed that the asteroid
belt in our solar system could have
formed in one of two ways one there
existed a planet between Mars and
Jupiter that broke up into the belt due
to a collision with another celestial
body or to the rock material in the
asteroid belt was unable to fuse into a
planet like the others due to Jupiter's
tremendous gravitational force asteroids
can be anywhere from a few feet to a
several kilometers in diameter the
largest asteroid on the belt is known as
Sarris it is 950 kilometers right so
large that it actually has its own
classification called the dwarf planet
can you find out the reason why Pluto
was demoted from the status of planet to
a dwarf planet like cirrus what is the
main difference between a planet and an
asteroid
