The Sun
- our average middle-age yellow star contains
more than 99% of all the matter in the solar
system. (center of the solar system)

holds all planets in orbit by its gravity
provides almost all energy found on
Earth
made of gas 70% hydrogen 29%
helium 1% other gases

Distance from Earth = 93 million miles or
150 million kilometers.
The distance from Earth to the sun is called
an Astronomical Unit – (A.U.)
it takes 8 minutes for light to travel this
distance.

Diameter of the sun is 110 times the
diameter of the Earth.

Mass is 333,000 times greater than
Earth.
Density = ¼ that of Earth – reason why sun
is less dense than the Earth is because it is a
ball of gas
