A day on mercury is very long
One day on mercury lasts almost 59 days on
earth.
A year in mercury is very short. It takes earth
365 days to go round the sun.
A year in mercury is only 88 earth days.
Since mercury’s year is so short, and it’s day is
so long, the planet only has 3 days for every 2
years.
► Days
on Venus are very long.
► One day is as long as 243 days on earth.
► A year is only 255 earth days long. So, a day is
longer than a year in Venus.
► Venus orbits around the sun.
► It spins on it’s axis.
► On Venus the sun rises in the west and sets on the
east. This is because it spins backwards on it’s
axis. In other words, it spins on the opposite
direction of the earth.
EARTH OUR PLANET!!!

meteors hit the Earth's ground, it exploded and sent a massive amount of water
from it. And that’s how we got the ocean.
The water covers 70 % of the Earth. In other words two thirds.
It has vast platues ( low lying, flat land. )
The Earth is the only planet with living organisms. It is also known for its magnificent
beauty.
It spins like a top on its axis
The earth travels around the sun at about 67,000 miles per hour and one year is one
trip round the sun.
Our earth can bend light. For example, when we are on the earth, the stars twinkle
because there are some certain gases that make them twinkle while in space, they
do not twinkle.

Neptune has no solid ground. It's atmosphere is made of
gases
It’s winds are fierce. So fierce that it could blow you away.
MOON

The moon has many craters.
The Moon may have formed as the result of a giant collision between a
planet-like body and Earth. Scientists believe the collision happened about 4.6
billion years ago, when Earth was still forming. The collision blasted off some
of Earth's outer mantle into space.
Soon, the material orbiting Earth began
