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