OUR SOLAR SYSTEM
By Chloe Beard
The Sunweight: The sun weighs 1 duodecillion kilograms
(two billion billion billion tones).
INFOThe Sun has an amazing diameter of 1,390,000 km,
It’s CORE temperature is 15 million º C,
The Sun is about 4.5 BILLION YEARS old. It will
probably continue to exist in its present FORM for
about another 5 BILLION YEARS before running
out of helium and hydrogen, leaving it to explode.
Weight: Earth weighs about 6,000,000,000,000,000,000,000,000 kilograms.
INFOEarth is east of Mars and west of mercury. It is 70% covered in water and
the other 30% in land.
the earth is 4.7 billions years old according to scientists.
Earth's biosphere has significantly altered the atmosphere and other
abiotic conditions on the planet, enabling the proliferation of aerobic
orgasims as well as the formation of the ozone layer which, together
with Earths magnetic field, blocks harmful radiation, permitting life on
land.
Weight: The mass of Venus is 5.36660262 x 1021 tons.
Facts: As the second planet to the Sun in the solar system, it is a closest
neighbour to the Earth. Known commonly as Morning or Evening star,
Venus appears in the sky just before sun rise or just after sun set. It is
brighter than stars and can be seen in broad daylight also. It is called
an inferior planet in that it is closer to the sun than the Earth. The planet
is named after the roman goddess of love and beauty.
Many space missions sent by both USA and USSR have given more
details about the planet. Some of the space missions are still in the
orbit round the planet. Many interesting features and facts about the
planet have been revealed by the studies made out of the different
missions. This is an attempt to see the overall view of the researches
made so far.
Weight: Mars weighs: 6.4185×1023 kg
Facts:
Mars has a very thin atmosphere, mostly carbon dioxide, but
dust storms can cover the whole planet for months at a time.
About every two years the Earth and Mars come close together.
The planet has two moons, Diemos and Phobos.
Mars, the fourth planet from the Sun, is commonly referred to as
the Red Planet due to its reddish appearance from Earth. The
planet is named after the Roman God of War, Mars. It is the
seventh largest planet in our solar system. The yellow-orange
colour of the Martian surface is due to the presence of oxidized
iron in the regolith. The pink-orange colour of the sky is caused
by extremely fine red dust that is suspended in the thin
atmosphere of Mars.
Weight: The weight of Mercury is 3.3022 x 1023 kgs
Facts: Mercury is a battered and baked planet just
larger than Earth's moon. Evidence of heavy
bombardment from the chaos of the formation of the
solar system is left in the hundreds of craters and
resulting lava flows on this small, barren planet. The
largest crater is Beethoven at 643 km in diameter and
is the largest in the solar system. The largest feature,
Caloris Basin, is 1300 km in diameter and was probably
caused by an impact from an object larger than 100
km in diameter. Some craters have ice in them even
though the planet is so hot because the sun never
reaches into the shadows due to the planet's tilt and
orbit. With no atmosphere, there is a temperature
difference of about 600 degrees between the coldest
spots and hottest spots on the planet.
Weight: Mercury is about 317.8
Facts:
Jupiter takes about 12 years to orbit the sun and rotates in
about 10 hours. This short Jupiter "day" is amazing since the
planet is roughly 11 Earth diameters wide.
The planet had 39 known moons at one and a slight ring of
smoke-sized particles and dust. The planet contains 71% of
the planetary matter in the solar system and so its huge
gravity pulls every object toward it. In fact, most of its
moons were captured rather than forming with Jupiter.
Scientists watched in awe as comet Shoemaker-Levy 9
broke up and smashed into Jupiter making explosions the
size of the Earth.

Facts:
Uranus is much smaller than Jupiter and Saturn, but with a
diameter of 51,118 km, it is still over four times that of Earths. It
would take 15 of our planet to equal the mass of Uranus.
Uranus is the seventh planet from the Sun, and the third-largest
and fourth most massive planet in the Solar System It is named
after the ancient Greek deity of the sky Uranus, the father of
Kronos (Saturn) and grandfather of Zeus (Jupiter). Though it is
visible to the naked eye like the five classical planets, it was
never recognized as a planet by ancient observers because of
its dimness and slow orbit. Sir William Herschel announced its
discovery on March 13, 1781, expanding the known boundaries
of the solar system for the first time in modern history. This was
also the first discovery of a planet made using telescope.
Weight: Neptune is about 17 earths.
Facts:
Neptune is the eighth and outermost-known planet from the
Sun in the Solar System. Named for the Roman god of the sea,
it is the fourth-largest planet by diameter and the third-largest
by mass. Neptune is 17 times the mass of Earth and is slightly
more massive than its near-twin Uranus, which is 15 Earth
masses and not as dense. On average, Neptune orbits the Sun
at a distance of 30.1 AU, approximately 30 times the Earth-Sun
distance. Its astronomical symbol , a stylized version of the God
Neptune's Trident
Discovered on September 23, 1846,[1] Neptune was the first
planet found by mathematical prediction rather than by
empirical observation. Unexpected changes in the orbit of
Uranus led astronomers to deduce that its orbit was subject to
gravitational perturbation.
Weight: The mass: 5.6846×1026 KG 95.152 Earths
Facts:
Saturn is the sixth planet from the Sun and the second largest planet
in the Solar System, after Jupiter. Saturn, along with Jupiter, Uranus
and Neptune .
The planet Saturn is composed of hydrogen, with small proportions of
helium and trace elements. The interior consists of a small core of
rock and ice, surrounded by a thick layer of metallic hydrogen and a
gaseous outer layer. The outer atmosphere is generally bland in
appearance, although long-lived features can appear. Wind speeds
on Saturn can reach 1,800 km/h, significantly faster than
those on Jupiter. Saturn has a planetary magnetic field
intermediate in strength between that of Earth and the more
powerful field around Jupiter.
