Transcript of "The solar system blog"

  1. 1. Which is the biggest planet?How many planets are there betweenthe Earth and the Sun?What other elements are there in theSolar System?How many planets are in The Solar System?
  2. 2. The Solar System consists of the Sun, eight plantes and their moons, cometsand asteroids. They are all called celestial bodies.Everything in the Solar System orbits the Sun.
  3. 3. The Sun is the largest celestial body, It is much bigger thanany planet.It is a yellow star which provides the light and the heatneccesary for life on earth,It is at the centre of the Solar System.The Sun rotates on its own invisible axis.
  4. 4. There are eight large celestial bodies called planets.Each planet rotates on its own invisile axis.VenusEarth
  5. 5. Each planet also orbits the Sun.Terrestrial Gas giantsMercury JupiterVenus SaturnThe Earth UranusMars NeptuneThey are small and mainly made up of rock They are large and are made up of gasesThe Planets are classified into two groups:
  6. 6. This picture shows amoon orbiting aplanet. An orbit isthe path followed bysomething thatrevolves, or goesaround somethingelseNatural Satellites are smaller celestial bodies, such as moons, which orbittheir planets.
  7. 7. An asteroid trail movieIn the Solar System there are thousands of tiny, rocky celestial bodies calledasteorids.They have different shapes.
  8. 8. Comets are small celestial bodies made up of ice, dust and rock.They have bright tails which point away from the Sun. We can onlysee the tail of a comet when it is close to the Sun.
  9. 9. The Earth revolves around the Sun. Its orbit is an elongated circle, called ellipse.The Earth take exactly 365 days and 6 hours to complete its orbit. Our “normal”calendar years are only 365 days long.
  10. 10. The Earth is a sphere. It rotates on its own invible axis, which pases throughthe North and South Poles. It takes 24 hours to complete this rotation.One half ofthe Earth isfacing theSun. In thishalf it is day.This half isfacing awayfrom the Sun.It does notreceivesunlight. Inthis half it isnight.The Earth always rotates in the same direction. Consequently , the Sun always rises inthe east and sets in the west.
  11. 11. Sun rise Sunset
  12. 12. North hemisphereSouth hemisphereIn geometry it is an exact half of a sphere.It also refers to half of the Earth
  13. 13. The Earth´s axis is slightly tilted.This hemisphere is tilyedaway from the Sun. Itreceives less light and heat. Itis winter in this hemisphere.This hemispehere istilted towards the Sun, Itreceives more light andheat. It is summer inthis hemisphere.This hemispehere istilted towards theSun, It receivesmore light and heat.It is summer in thishemisphere.This hemisphere is tilyed awayfrom the Sun. It receives less lightand heat. It is winter in thishemisphere.
  14. 14. The Moon is the Earth´s only natural satellite. It takes27,3 days to orbit the Earth.The Moon rotates on its axis in the same time it takes the Moon to orbit theEarth. The same side of the moon always faces the Earth.
  15. 15. New MoonFirts quarterFull MoonLast quarterWhen we look to the Moon from Earth, its appearance changes throughout thelunar month. These changes in appearance are called lunar phases.NEW MOON:no part of theMoon isvisiblebecause theside of theMoon facingthe Earth isnot being lit bythe Sun.FIRST QUARTER: one half of the Moon is being lit bydirect sunlight. This iluminated half is increasing.FULLMOON:the sideof theMoonfacing theEarth isbeing litby theSun.LAST QUARTER: the other half of the Moon is being litby direct sunlight. This illuminated hald is decreasing.
  16. 16. MoonEarthSunSometimes during their orbits, the Moon, the Earth and the Sun align and an eclipse occurs.During a lunar eclipse, the Earth passes between the Sun and the Moon,and blocks the Sun´s light. The Earth´s shadow moves across the surface ofthe Moon.
  17. 17. During a solar eclipse the Moon passes between the Earth and the Sunand it blocks the Sun´s light and projects a shadow on the Earth. Whenthe Moon and Sun are in the perfect line it is called total eclipse.
  18. 18. Never look at the Sun duringan eclipse without adequateprotection. You can look atthe Sun without filters onlywhen it is totally eclipsed.
  19. 19. A star is a spherical body which generates light and heat thriugh nuclearreactions. Most stars consist of the gases hydrogen and helium.Stars have different characteristics:Colour: Depending on their temperature, stars can be red,orange, yellow, white or blue.Size: all stars are enormous, but some are larger thanothers.Luminosity: this refers to the amount of light from the starwhich reaches the Earth.
  20. 20. Stars are divided into 88 groups or constellations to make identification easier.The constellations have the names of characters from classicalmythology orthe names os animals and objects because of the shapes they form.
  21. 21. The Ursa major, or the Big Bear, can be seen all year.
  22. 22. Orion constellation can only be seen in winter.
  23. 23. Hercules constellation can only be seen in summer.
  24. 24. A nebulae is a cloud of dust and gas. Some nebulae are illuminatedby stars near them. New stars are formed in some nebulae.
  25. 25. Galaxies are enormous group os stars, gases and dust.There are three types:ellipticalspiralirregular
  26. 26. Our Solar System is on the edge of galaxy called the Milky Way. All the starswhich we can see belong to this galaxy.
