• The star of our solar system is a huge ball
of hot, glowing gases. At about 333,000
times the mass of Earth, the sun contains
about 99.8 percent of all the mass in the
solar system. Heat and light from this
average-size star travel a mean distance
of 92.96 million miles(149.6 million
kilometers) to reach Earth and support all
life on our planet.
• Mercury is the planet closest to the Sun in
our Solar System. This small, rocky planet
has almost no atmosphere. Mercury has a
very elliptical orbit and a huge range in
temperature. During the long day time the
temperature is hotter than and oven;
during the long night, the temperature is
colder than a freezer.
• Venus is the second planet from the sun in
our solar system. This planet is covered
with fast-moving sulphuric acid clouds
which trap heat from the Sun. Its thick
atmosphere is mostly carbon dioxide.
Venus has an iron core but only a very
weak magnetic field.
• The Earth is the third planet from the Sun
in our Solar System. It is the planet we
evolved on and the only planet in our
Solar System that is known to support life.
• Mars, the red planet, is the fourth planet
from the Sun and the most Earth-like
planet in our Solar System. It is about half
the size of Earth and has a dry, rocky
surface and a very thin atmosphere.
• Jupiter is the fifth largest planet in our
Solar System. This gas giant has a thick
atmosphere, 39 known moons, and a
dark, barely-visible ring. Its most
prominent features are bands across its
latitudes and a great red spot.
• Saturn is the sixth planet from the Sun in
our Solar System. It is the second largest
planet in our Solar System. It has beautiful
rings that are made mostly of ice chunks
that range in size from the size of a
fingernail to the size of a car. Saturn is
made mostly of hydrogen and helium gas.
• Uranus is the seventh planet from the sun
in our solar system. This huge, icy planet
is covered with clouds and is encircled by
a belt of 11 rings and 22 known moons.
Uranus’ blue colour is caused by the
methane in its atmosphere; this molecules
absorbs red light.
• Neptune is the eighth planet from the sun
in our solar system. This giant, frigid
planet has a hazy atmosphere and strong
winds. This gas giant is orbited by eight
moons and narrow, faint rings arranged in
clumps. Neptune's blue color is caused by
the methane in its atmosphere; this
molecule absorbs red light.
• Pluto is a dwarf planet that usually orbits past the
orbit of Neptune. It was classified as a dwarf planet
in 2006; before that it was considered to be a planet,
the smallest planet in our solar system. Pluto is
smaller than a lot of the other planets' moons,
including our moon. Pluto is the only "planet" in our
solar system that has not been visited by our
spacecraft yet. We only have blurry pictures of its
surface; even the orbiting the Earth can only get
grainy photos because Pluto is so far from us. In
2015, a spacecraft called New Horizons (launched
by NASA in 2006) will visit Pluto.
• The moon is Earth’s only natural satellite.
The moon is a cold, dry orb whose surface
is studded with craters and strewn with
rocks and dust. The moon has no
atmosphere. Recent lunar missions
indicate that there might be some frozen
ice at the poles.

about the Solar System. I hope you
learned things. By Gabby Rosandic
