DESCRIPTION

Presentation about the Solar System. It includes celestial bodies such as the Sun, the Moom, comets, asteroids, meteorids and of course; the main features of the eight planets. For primary students in grade 4 in Madrid bilingual state schools.

Our solar system is made up by celestial bodies. Celestial bodies are natural objects in the sky and they can be:

-The Sun

-Planets

-Satellites

-Comets

-Asteroids

-Meteorids

Page 3: Celestial bodies in the Solar System: the Sun, planets, satellites, comets, asteroids and meteorids

It is a star because it produces light and

heat. The Sun is at the centre of the Solar

System.

Page 4: Celestial bodies in the Solar System: the Sun, planets, satellites, comets, asteroids and meteorids

There are eight planets that orbit, move around or revolve around the

Sun.

Page 5: Celestial bodies in the Solar System: the Sun, planets, satellites, comets, asteroids and meteorids

Mercury is the planet nearest to the Sun. This small and hot

planet has no moons.

It takes 58 days to rotate on its axis and

88 days to revolve around the Sun.

Its temperature goes from 465ºC to -184ºC.

Page 6: Celestial bodies in the Solar System: the Sun, planets, satellites, comets, asteroids and meteorids

Venus is the the hottest planet because it can reach 449ºC and it has no moons. It needs -243 days to rotate on its axis and 224 days to

orbit the Sun.

Venus is known as the “morning star” or “evening

star”.

Page 7: Celestial bodies in the Solar System: the Sun, planets, satellites, comets, asteroids and meteorids

We live on the Earth, the third planet from the Sun. It takes 24 hours to rotate

and 365 days to orbit the Sun.

It has one moon.

Page 8: Celestial bodies in the Solar System: the Sun, planets, satellites, comets, asteroids and meteorids

Mars is the most Earth-planet in the

Solar System. It has two moons and its

atmosphere is mainly composed of carbon

dioxide.

The biggest vocano in the Solar System

is there.

Page 9: Celestial bodies in the Solar System: the Sun, planets, satellites, comets, asteroids and meteorids

This is the surface of Mars. There is ice on both north and south poles.

Mars needs more than 24 hours to rotate on its axis and 686 days to revolve around the Sun.

Jupiter is a gas giant and the biggest planet in our Solar System. It is so big that the rest of

the planets could fit inside it. It has 63

moons.

It needs 10 hours to rotate on its axis and

almost 12 years to orbit the Sun.

Page 11: Celestial bodies in the Solar System: the Sun, planets, satellites, comets, asteroids and meteorids

Saturn is a gas giant which has beautiful rings

made of ice and rocks. It has 33

moons.

It needs 10 hours to rotate on its axis and more

than 29 years to revolve around

the Sun.

Page 12: Celestial bodies in the Solar System: the Sun, planets, satellites, comets, asteroids and meteorids

Uranus is a light blue gas giant with 27

moons.

This planet is extremely tilted and a gas called methane

gives it the blue colour as it absorbs

red light.

It needs 18 hours to rotate on its axis and 84 years to revolve

around the Sun.

Page 13: Celestial bodies in the Solar System: the Sun, planets, satellites, comets, asteroids and meteorids

Neptune is a blue gas giant because its atmosphere is

also composed of methane. It has 13 moons and it

needs 16 hours to rotate on its axis and more than 164

years to orbit the Sun!

So, it is the farthest planet to the Sun.

The poles are in constant darkness of sunlight for 40

years at a time.

It is the only known planet where living things can survive. This is because:

- It has enough oxygen in its atmosphere.

-There is water on its surface.

-Its warm temperature: it is not too hot or too cold.

Page 16: Celestial bodies in the Solar System: the Sun, planets, satellites, comets, asteroids and meteorids

The Moon is the Earth’s only natural satellite. It rotates on its axis at the

same time that the Earth, so it needs 24 hours to do so. It also takes about

28 days to orbit the Earth.

Remember!: Satellites, like planets, do not produce light and heat. The Moon shines because it reflects off the light

from the Sun.

They are space rocks. Some asteroids are as big as mountains.

Some meteorids are as small as a grain of sand.

PLANET

Page 20: Celestial bodies in the Solar System: the Sun, planets, satellites, comets, asteroids and meteorids

A comet is like a big snowball with a rock in the middle.

Comets start to melt when they get close to the Sun. A melting

comet has a long tail.
