Origin of the
Universe |
The Earth has a unique
solar system. It has an
oxygen rich atmosphere
and has liquid water.
These factors have
enabled the Earth to
evolve life, in all its
many forms. The Earth
is 149.6 million km,
93 million miles from
the sun. It takes the
earth 365.25 days to
rotate around the sun.
The oldest rocks
found in the earths
crust date to about
3,900 million years ago.
The Earths age is about
4,600 million years.
Its surface area is
510 million km squared.
(317 million sq miles The
oldest evidence of life is
3,500 million years ago.
The number of living species
is at least 10 million.

Mars is 0.107 the size of our Earth. It averages 227.9
km/141.6 million miles away from the sun.
It was named after the Roman God of war because of its
colour of blood.
It may be smaller than the earth, but it turns on its
axis much more slowly. A day on Mars is only 41
minutes longer than ours. However its orbital period is 687 Earth days.
Mars has two small moons Phobos and Deimos.
Phobos means "fear" and Deimos means "terror".
Phobos orbits Mars every 7 hours and 40 minutes.
Deimos however takes longer at 30 hours.

Jupiter is the largest of the planets. It is 318 times
the size of Earth.
It can be seen with the naked eye.
It has 16 moons, and is on average 778.3 million km from
the sun (483.7 million miles).
It has a rock core but mostly consists of gas in various
states. A giant wind system gives the planet a banded look.
Some of the winds move at up to speeds of several hundred
kilometers per hour.
It is also the fastest spinning planet.

Venus is 0.81 times the
size of the Earth.
It averages 108.2 million km,
67.2 million miles
from the sun. Venus
shines brightly in the
sky and has often been
called the evening star.
Its atmosphere is made
up of sulphuric acid
and there is extreme
heat and pressure.

Jupiter has many moons. Their orbital periods vary from
0.295 days to 758 days!!
Europa: has sufficient internal heat to have liquid water
seas beneath its surface.
Io: Looks orange because of debris on the surface.
It has the first active volcanoes to be discovered outside of Earth.
Ganymede: the largest moon in the solar system.
It is larger than mercury and Pluto.
The Voyager probe took over 30,000 images of Jupiter
and its moons. |

Saturn is famous for its rings.
Saturn has many moons,
more than any other planet.
at least 18. It is 95
times the size of Earth,
and averages 1,427 miles
away from the sun
(886.9 million miles)
Saturn's rings are made
of dust particles
and ice covered rock
particles. They are less
than 200m (656 ft) thick,
but over 270,000 km
(167,800 miles)
in diameter.
Saturn has three moons
that share the same
orbit- Tethys, Telesto
and Calypso. |

Neptune is named after the Roman God of the
Sea.
Neptune is 17 times larger than the Earth. and has 8
moons. The moons and its rings were discovered by the Voyager 2 probe. |
Mercury is only 0.055 the size of the Earth. It is on
average 57.9 million km, 36 million miles away from the sun.
It is named after the messenger of the Roman Gods because
it travels quickly across the night sky.
A day on Mercury lasts 176 earth days. However
a year on Mercury only lasts 88 Earth days as that is the time
it takes to orbit the sun. |
Uranus is 14.5 times the size of Earth. It
is 2,871 million km , 1,184 miles, from the sun. It is called after
Urania, the ancient Greek muse of astronomy.
Its moons are named after characters from Shakespeare
plays.
It has about 15 moons and more may yet be
discovered. |

Asteroids are chunks of rock that orbit the sun. The
first ever discovered was Ceres which has a diameter of 933 km, 580
miles.
It is only a matter of time before the earth is again
struck by an asteroid. |
Meteorites
The largest meteor to hit the Earth weighed about 60
tonnes, it fell at Hoba West in Southern Africa.
Most meteorites that land on Earth are "stones"
Tsar Alexander of Russia had a sword made from an iron
meteorite last century. |
The Hubble Space Telescope uses a large mirror to
collect light. It is then directed into one of the scientific packages
by use of another mirror. Because it is in space and above Earths
atmosphere it can see much further and clearer than telescopes on Earth
