Solar System
Our solar system has nine planets: Mercury, Venus, Earth, Mars,
Jupiter, Saturn, Uranus, Neptune and Pluto.
Pluto is the smallest,
coldest, and most distant
from the sun.
Smaller than earth’s
moon, Pluto remains an
unexplored celestial
snowball 4 billion miles
from the sun.
.
Mars is a small rocky planet.
Sometimes there are great
dust storms on Mars although
scientist are sure Mars once
had water. Scientist believe
that 3.5 billion years ago, Mars
had the largest flood in the
solar system. Mars also has
two small moons, Phobos and
Deimos.
This planet is Venus. If you would
look at Venus and Earth they would
look like they would be twins.
Venus is covered by thick, rapidly
spinning clouds that trap surface
heat, creating a scorched
greenhouse-like world with
temperatures hot enough to melt
lead and pressure so intense that
standing on Venus would feel like the
pressure felt 900 meters deep in
Earth’s oceans.
Earth is our home planet. It is
the only planet known in our
solar system that has life. Over
six billion people live on Earth.
Some facts are well known.
For instance, Earth is the third
planet from the sun and is the
fifth largest planet.
Jupiter is almost a “mini solar
system.” It has many moons
and rings. Jupiter is the
biggest planet in our solar
system. It looks a lot like a
small star. In fact, if Jupiter
had been between fifty to one
hundred times more massive,
it would have become a star
rather than a planet.
This planet is Saturn.
Saturn is a gas giant made
mostly of hydrogen and
helium. Saturn has rings
that are made mostly of
water ice. The particles in
the rings range in size
from dust mites to
houses! Saturn has at
least 30 satellites.
This planet is Uranus.
Uranus is known as a “gas
giant” because it has no
solid surface. It gets it’s
blue-green color from
methane gas above the
deep cloud layers.
Methane absorbs red
light and reflects blue
light. Uranus has about 20
moons.
This planet is Neptune.
Neptune was discovered
in 1846. Neptune orbits
the sun every 165 years.
Neptune has the smallest
diameter of our solar
system’s giant gas planets
(including Jupiter, Saturn,
and Uranus).
Any Question ?
