Unit 16: Astronomy Assignment 1- The Solar
System.
What is the definition of the solar system? The solar system is a
collection of eight large planets and five dwarf planets along with
their moons in course around the sun together with smaller bodies in
the form of comets, asteroids and meteoroids. The solar system
consists of the following planets which are, Jupiter, Saturn, Uranus,
Mars, Neptune, Venus, Earth and Mercury. The solar system is found
in the Milky Way galaxy.
Figure 1 above shows the solar system with the different planets,
and other bodies for instance asteroids and comets.

planet from the sun. It
has a large spot on its

thin rings that are
difficult to see. NASAS

discovered the rings in
1979. The rings are
made up mainly of
dust. Jupiter takes 12
earth years to make
one revolution
therefore one year on

length is 24.6 hours.
One year is equal to
687 Earth days. Mars
has two moons. It is
also known as the
terrestrial. The planet

carbon dioxide. It
contains small
amounts of oxygen,
water vapour and
nitrogen. Mars has no
water on its surface.
Mars can be seen with
the naked human eye.
It was known about
4,000 years ago. Mars
years are much longer

The clouds on Venus

sulphur dioxide. Venus
