Makes life on our planet possible by
giving us great amounts of light and heat.
Contains about 98% of the mass of the
entire Solar System.
Is just a medium sized star (yellow
dwarf). It is about 1.4 million kilometers
in diameter.
Sun Facts
Is the center of our Solar System. All the
planets and other objects orbit around it.
Is very gaseous, and made up mostly of
hydrogen.
Contains dark spots that are known as
sunspots.

Contains the eight 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 now called a minor or
dwarf planet that is far from the sun.


All the objects in our Solar System orbit

Solar System could fit in it many times.
Many scientists believe that our Solar
System is over 4.6 billion years old.

Sailing Out to Space
I dream of sailing out to space,
Upon a yacht of stars.
With port holes all along the sides,
I'd gaze amazed at Mars.
With stars in front and stars behind,
And planets far and near,
I'd sail my yacht around the rings,
Of Saturn with a cheer.
