• Contains the nine planets and other smaller objects such as minor
planets, comets, meteoroids and cosmic dust.
The first four inner planets (Mercury, Venus, Earth, and Mars)
are relatively small and resemble the Earth in composition
(rocky).
The next four planets (Jupiter, Saturn, Uranus, and Neptune)
are much larger planets and are very gaseous in nature. Pluto is
the smallest planet and is the farthest away from the Sun.
All the objects in our Solar System orbit the Sun. It is so big
that everything in our Solar System could fit in it many times.
Many scientists believe that our Solar System is over 4.6 billion
years old.
– Infinite space/place that contains galaxiies, costellations, stars, planets, comets,
asteroids, black holes,nebulas, novas, meteoroids ( meteorites-meteors), moons
etc…
• Meteoroids could be tiny particles left behind by a comet or
can even be an asteroid. Meteoroids are in orbit around the
Sun.
Meteorites are rocks from space that strike the Earth.
Meteors (also known as shooting stars) are the same kind of
object as meteorites, only they are still in space.
