Planet Mercury
• Did you know that Mercury is the closest planet to the Sun? Mercury
is hard to see but when it is the Eclipse you can see it clearly if you are
in space or if you have a telescope.Thirteen times a century, Mercury
can be observed from the Earth passing across the face of the Sun in
an event called a transit. The next will occur on the 9th May 2016.
• Mercury is the smallest planet in the solar system. Mercury is very
dense. It is the second densest planet in the solar system. Would you
like to learn more about other planets? Keep reading to find out more
about our Solar System.
Planet Venus
• Venus is the second planet away from the Sun and is the second brightest
object in the night sky after the Moon. Venus is the second largest
terrestrial planet and is sometimes referred to as the Earth’s sister planet
due the their similar size and mass. The planet’s orbit around the Sun takes
225 Earth days, compared to the Earth’s 365. Terrestrial planet is like an
• The planet’s orbit around the Sun takes 225 Earth days, compared to the
Earth’s 365. While its size and mass are similar to Earth, the small asteroids
are crushed when entering its atmosphere, meaning no small craters lie on
the surface of the planet. The pressure felt by a human on the surface
would be equivalent to that experienced deep beneath the sea on Earth.
Planet Earth
• Earth is the place where we live. We have to care for the nature and
all the creatures that live with us. Earth is the third planet away from
the Sun and it is the largest of the terrestrial planets! Do you know
anything about the planet Earth? The Earth takes a year to do a full
turn, which does a half turn evey six months.
Planet Mars
• Do you think there is life on Mars? There is evidence that show there
is life on mars. Mars is the fourth planet away from the Sun named
after the Roman God.
• There is life in space. Pictures taken in 1900 think they have seen
alien life. There is some opinion about aliens living on the Mars but
we don’t know that for sure. They are just theories of people.
Planet Jupiter
• Do you know anything about the planet of gas, Jupiter? Well, as you
may now know it’s the planet of gas and if you want to know more
about it then read on!
• Did you know that Jupiter has the shortest day of all the planets due
to the fact it is the brightest planet in space. Scientists are still not
sure how many stars there are in space as its impossible to count
them all howerver, with bigger telescope you can see more stars that
shine a little bit less brighter than others. Hope you learnt more
about Jupiter.
Planet Saturn
• Do you know anything about the planet Saturn? Saturn is the fifth
brightest planet in space due to the fact it is also named after the
Roman’s God Sartunus. Saturn makes a turn every 10 hourse and 34
• Saturn has four main groups of rings and three fainter,
narrower ring groups. These groups are separated by gaps called
Planet Uranus
• Uranus is the seventh planet away from the Sun. Uranus was officially
discovered by Sir William Herschel in 1781. Every 17 hours 14 seconds
it does a full turn.
• It is too dim to have been seen by ancient civilisations. At first
Herschel thought it was a comet, but several years later it was
confirmed as a planet. Herscal tried to have his discovery named
“Georgian Sidus” after King George III. The name Uranus was
suggested by astronomer Johann Bode. The name comes from the
ancient Greek deity Ouranos.
Planet Neptune
• Neptune is the eight planet away from the sun making it the most distant
in the solar system. This gas giant planet may have formed much closer to
the Sun in early solar system history before migrating to its present
position. Neptune was not known to the ancients. It is not visible to the
naked eye and was first observed in 1846. Its position was determined
using mathematical predictions. It was named after the Roman’s God of
the sea.
• Neptune spins on its axis very rapidly:
• Its equatorial clouds take 18 hours to make one rotation. This is because
Neptune is not solid body.
• Neptune is the smallest of the ice giants:
• Despite being smaller than Uranus, Neptune has a greater mass. Below its
heavy atmosphere, Uranus is made of layers of hydrogen, helium, and
methane gases. They enclose a layer of water, ammonia and methane ice.
The inner core of the planet is made of rock.
Planet Pluto
• Discovered in 1930, Pluto is the second closest dwarf planet to the Sun and was
at one point classified as the ninth planet. Pluto is the largest dwarf planet but
only the second most massive, with Eris being the most massive. Pluto is named
after the Greek’s God of the underworld:
This is a later name for the more well known Hades and was proposed by Venetia
Burney an eleven year old schoolgirl from Oxford, England.
• Pluto was reclassified from a planet to a dwarf planet in 2006:
This is when the IAU formalized the definition of a planet as “A planet is a
celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its
self-gravity to overcome rigid body forces so that it assumes a hydrostatic
equilibrium (nearly round) shape, and (c) has cleared the neighborhood around
its orbit.”
• Pluto was discovered on February 18th, 1930 by the Lowell Observatory:
For the 76 years between Pluto being discovered and the time it was reclassified
as a dwarf planet it completed under a third of its orbit around the Sun.
• One million Earths could fit inside the Sun:
• If a hollow Sun was filled up with spherical Earths then around
960,000 would fit inside. On the other hand if these Earths were
squished inside with no wasted space then around 1,300,000 would
fit inside. The Sun’s surface area is 11,990 times that of the Earth’s.
Eventually, the Sun will consume the Earth:
• When all the Hydrogen has been burned, the Sun will continue for
about 130 million more years, burning Helium, during which time it
will expand to the point that it will engulf Mercury and Venus and the
Earth. At this stage it will have become a red giant.
• The Moon (or Luna) is the Earth’s only natural satellite and was formed 4.6
billion years ago around some 30–50 million years after the formation of
the solar system. The Moon is in synchronous rotation with Earth meaning
the same side is always facing the Earth. The first unmanned mission to the
Moon was in 1959 by the Soviet Lunar Program with the first manned
landing being Apollo 11 in 1969.
• The dark side of the moon is a myth:
• In reality both sides of the Moon see the same amount of sunlight however
only one face of the Moon is ever seen from Earth. This is because the
Moon rotates around on its own axis in exactly the same time it takes to
orbit the Earth, meaning the same side is always facing the Earth. The side
facing away from Earth has only been seen by the human eye from
