• The solar system is a system of planets, satellites, asteroids, comets, dust, gas and other bodies that orbit around a star, bound to it by the stellar gravitational force.
• 5. Thecentral star The Sun is the star of the planetary system in which the Earth is, so is the closest to the Earth and the sun with greater apparent brightness. Its presence or absence in thesky respectively determine the day and night. The energy radiated by the sun is used by photosynthetic beings, which are the basis of the food chain, making it the main source of lifeenergy. It also provides the energy that keeps running climate processes.
• 6. Inner planets Mercury Venus Earth Mars The members of this group are relatively small rocky planets: Mercury,Venus, Earth, Mars. Despite its initial resemblance have differences: Mercury and Venus are highly hot, while Mars during most of the year is terribly cold.
• 7. Outer planets JupiterSaturn Uranus Neptune are very different from the interior. They are much farther from the Sun, and are much larger. Jupiter, Saturn, Uranus and Neptune are giant gas planets with no solidsurface.
• 12. An eclipse is the obscuring of one celestial body by the interposition of another celestial body. This means that when a star is hidden by a short period in the light, aneclipse occurs. On earth eclipses occur two types: the moon and the sun. Lunar eclipses occur when the Earth passes between the sun dress and the moon and its shadow darkens thesatellite. Solar eclipses occur when the moon is between the sun and the earth, and its shadow is cast on any point on the surface of the earth
• 13. Satellites are objects or celestial bodiesthat orbit another celestial body larger. There are natural satellites such as the Moon, and artificial satellites, including meteorological and communications man in orbit around Earth.
