Solar System
 Our solar system is huge .
 We have 8 Planets in our
solar system.
sun
Our sun is actually a star.
The sun is 27,000,000 degrees
farenheight
The Sun or Sol, is the star at the
center of our solar system and is
responsible for the Earth’s climate
and weather. The Sun is an almost
perfect sphere with a difference of
just 10km in diameter between the
poles and the equator. The
average radius of the Sun is
695,508 km (109.2 x that of the
Earth) of which 20–25% is the
core.
Mercury
 Mercury is as big as our
moon.
 It is the closest to the sun.
Venus
 Venus is the second planet
from the sun.
 Venus is the sixth largest
planet in the Solar System.
EARTH
 The Earth is the planet we
live.
 Water is 75 percent of our
planet.
Mars
 Mars orbits the sun every
687 Earth days.
 A Mars’ day is longer than
on Earth.
Asteroid belt
 26 very large asteroids have been
discovered, which is probably most
of the big ones. But there are still
millions of smaller ones that we
have yet to see because they are
too tiny, only a mile or so across.
Jupiter
If you weigh 100 pounds on
Earth, you would weigh 264
pounds on Jupiter.
Jupiter has the fastest
rotation of any planet in our
solar system.
SATURN
 A year on Saturn is equal to
29.5 Earth Years.
 Diameter of Saturn is
119,871 km (74,500 miles).
Uranus
 Uranus is named after the Greek
god of the sky. Uranus was the
husband of Gaia, the goddess of
the Earth.
 Uranus is considered unusual
because the planet is tipped on its
side. The poles actually point
towards the Sun. This is due to the
fact that its magnetic field is tilted
60 degrees from the axis of
rotation.
Neptune
 Neptune has strong winds which
is more than any other planet in
the Solar System. Winds on
Neptune can get up to 2,000
km/hour (1,200 miles/hour). “The
Scooter” is a cloud that moves
around Neptune about every 16
hours.
 In 1898 Voyager 2 conducted a
flyby of Neptune and confirmed
the presence of a magnetic field
around the planet. It also found
that the field was tilted like
Uranus’. Voyager 2 also
discovered six new moons that
orbit Neptune and that the planet
has more than one ring.
PLUTO
 As of 2006, Pluto is not
longer considered a planet,
but rather designated as a
“dwarf planet,” meaning
that it is a planetary-mass
object being neither a
planet nor a satellite. Pluto
was declassified as a
planet by the International
Astronomical Union (IAU).
 Pluto has four identified
moons, Charon, the largest
is not much smaller than
Pluto itself. (Pluto is 2,280
kilometers wide, Charon is
1,212 kilometers wide). The
other 3 are Nix, Hydra, and
newly discovered S/2011 P
1 on July of 2011.
