This document provides an overview of the solar system, including its formation over 4.6 billion years ago with one star (the Sun) and eight known planets along with hundreds of smaller planets and asteroids. It describes each planet's key characteristics such as Mercury being the smallest terrestrial planet with no atmosphere or moons. Earth is the only planet that supports life and has one moon, while Mars has a thin atmosphere and two small moons. The outer gas giants include Jupiter, the largest planet composed primarily of hydrogen and helium, Saturn with its prominent ring system and 62 moons, Uranus which was discovered in the 19th century and rotates parallel to the solar plane, and Neptune with its blue atmosphere due to methane

3. CHARACTERISTICS
Formed 4.6 billion years ago
1 star (the Sun)
8 known planets
Hundreds of small planets and asteroids

4. THE SUN
SOLAR WIND.

5. THE SUN
It has six layers:
1. The core
2. Radiation zone
3. Convection zone
4. Photosphere
5. Chromosphere
6. Transition zone
7. Corona

6. MERCURY
● Terrestrial planet
● The smallest planet of the solar system.
● It has no satellites.
● Has no atmosphere.
● Highest number of impact craters in our solar
system.
● “Caloris Planitia” 1550 Km of diameter
Mercury
Roman mythology

7. VENUS
● It has no satellites.
● Has a really dense atmosphere and it reflects the
sunbeams, it is made sulfuric acid.
● The rotation of Venus is inverse from the rest of the
planets and slower, 1 day on Venus is equal to 240
days on Earth.
● It is called the “Morning or Evening Star”.
Venus
Roman mythology

8. EARTH
● Terrestrial planet.
● The only planet in our Solar System that supports
life.
● A day on the Earth lasts a little under 24 hours.
● A year on the Earth lasts 365.25 days.
● Earth atmosphere.
● We have a moon.
● It is formed by four layers:inner core, outer core,
mantle, crust.
● There is a lot we can still learn from our planet.

9. MOVEMENTS OF THE EARTH
There are two types of movements:
rotation and revolution.
1. Rotation
2. Revolution
This movements appear in other
planets, it can vary: the type of
orbit, the direction of the
movements.

10. MARS
• Terrestrial planet
• Has a thin atmosphere and water
• Red because of iron oxide (rust)
• Lots of investigation
• 2 satellites: Phobos and Deimos

11. ASTEROID BELT
● It is a circular disc made of asteroids.
● Located between Mars and Jupiter.
● The four largest asteroids of this belt are:
➢ Ceres.
➢ Vesta.
➢ Pallas.
➢ Hygiea.
EROS

12. JUPITER
It is the biggest planet of the Solar System and the closest
gaseous planet to the Sun.
Its composition is similar to the Sun´s one: hydrogen,
helium and small quantities of ammonia, methane, water
steam and others.
It has planetary rings, which are invisible from the Earth.
It has a lot of satellites, at least, 67 are known.
Fastest rotation among the planets of the Solar System.

13. SATURN
• It is a gas giant with an average radius about nine
times that of Earth.
• Saturn is named after the Roman god of agriculture.
• Saturn's interior is composed of iron–nickel and rock.
This core is surrounded by a deep layer of metallic
hydrogen, and finally outside a gaseous outer layer.
• Saturn has a pale yellow colour due to ammonia
crystals in its upper atmosphere.
• Wind speeds reach 1,800 km/h.
• Saturn has a prominent ring system.
• 62 known moons.
• Titan is Saturn's largest moon

14. URANUS
● It was discovered recently, 1880.
● Its rotation axis is almost parallel with the plane
of the solar system.
● The atmosphere is made of methane.
● We know 27 satellites.
● It has some rings.
Uranus
Greek mythology

15. NEPTUNE
● Its atmosphere is blue because of the methane.
● Its year lasts 165 years in the Earth.
● It has 14 known satellites.
● One of these satellites, called Titan, is bigger
than Pluto. Also, it is known that the orbit of Titan
goes in the opposite direction of the other
satellites.

16. NEW DISCOVERIES
• Water on pluto
