The Earth is the third planet from the
Sun and comes between the planet
Venus and the planet Mars.
The Earth takes 365¼ days to complete
its orbit round the Sun.
As the Earth orbits round the Sun it
turns on its axis, rotating right round in
24 hours. The side of the Earth that
faces the Sun has daytime and the side
of the Earth that is turned away from
the Sun has night-time.
The Earth is 93 million miles, or 150
million kilometres from the Sun.
The Earth’s diameter, the distance round
its middle at the Equator, is 7928 miles,
or 12760 kilometres.
The Earth differs from all the other
planets because it has such a wide
diversity of life and intelligent
beings. This has only been possible
because of the Earth’s atmosphere which
has protected the Earth and allowed life

Jupiter is the giant of the Solar System, with a
mass more than 300 times the mass of the
Jupiter has a diameter of 88,700 miles, or
Jupiter is the fifth planet in order from the Sun
and is about 483 million miles, or 777 million
kilometres from the Sun. The Earth is much
closer to the Sun than it is to Jupiter.
Jupiter is the stormiest planet in the Solar
There are 64 moons in total, four of which are
large enough to be easily observed with a

The Moon has no atmosphere and so we
can still see the damage caused billions of
As it rotates round the Earth we see
different fractions of the sunlit half, or
hemisphere, of the Moon. These are
known as the phases of the Moon, or
lunar phases. The Moon changes from a
thin crescent to a full moon and back again
to a crescent in one month (actually 29
days, which is a lunar month).
The first person to walk on the Moon was the American astronaut, Neil
Armstrong, who stepped out of his space landing craft, the Eagle, on 21 July
1969 with these famous words, “That’s one small step for man, one giant leap

The Titan is the largest moon of Saturn.
Titan's diameter is 50% larger than Earth's
natural satellite, the Moon, and it is 80%
Titan is primarily composed of water
ice and rocky material.
The atmosphere of Titan is largely
nitrogen; minor components lead to the
formation of methane–ethane clouds and
nitrogen-rich organic smog. The climate—
including wind and rain—creates surface
features similar to those of Earth.
Titan is 5,150 kilometres (3,200 mi) in diameter, compared to 4,879 kilometres
(3,032 mi) for the planet Mercury, 3,474 kilometres (2,159 mi) for the Moon, and
12,742 kilometres (7,918 mi) for Earth.
