It is the star at the center of our solar system .The Sun’s Life Cycle: The Sun’s Life Cycle The Sun is 4.5 billions years old. It has lived almost half its life. The Sun will die in 5 billion years.Size of The Sun: Size of The Sun The Sun’s radius is 6.955 x10 5 km. Or 109 times bigger than the Earth.The Sun is made of..: The Sun is made of.. The Sun is 73% Hydrogen and 24% Helium.Hot: Hot The Sun burns at 5500 o Celcius . And about 13.6 million o C at its core .Nuclear Fusion: Nuclear Fusion The Sun burns so hot at its core, Hydrogen joins together to form Helium. This is called nuclear fusion .A Special Star: A Special Star Even though The Sun is classified as a small yellow dwarf star, it is brighter than 85% of the stars in our galaxy.Very: Very GoodThe Universe: The Universe All Outer SpaceGalaxy: Stars go around the center of galaxies. Our solar system orbits the center of the Milky Way Galaxy. GalaxyThe Milky Way Galaxy: The Milky Way is 100,000 light years in diameter and 1000 light years thick. There are 200 to 400 billion stars in the Milky Way Galaxy. The Milky Way GalaxyThe Orion Arm: Our Sun is in The Orion Arm part of the Milky Way Galaxy. The Sun is 24,600 light years from the center of the Milky Way Galaxy. The Orion ArmTypes of Galaxies: Types of GalaxiesThe Local Group: The Milky Way Galaxy is part of a group of galaxies called The Local Group . These galaxies pull on each other through gravity . The Local GroupThe Local Group of Galaxies: The Local Group of GalaxiesThe Virgo Superclusters: Our Local Group belongs to the Virgo Supercluster , a group of similar Local Groups of galaxies. The Virgo SuperclustersThe Local Supercluster: The Virgo Supercluster belongs to a group of other Superclusters called The Local Supercluster of galaxies. The Local SuperclusterThe Visible Universe: The Local Supercluster is only a fraction of the galaxies in the Visible Universe . There are 170 billion Galaxies in the Visible Universe. The Visible UniverseThe Universe: Scientist still disagree on the size of the universe. Some say the universe is 1000 times bigger than the visible universe. Others say the universe is infinite (never ending). The UniverseVery Good: Very GoodThe Solar System: the sun system The Solar SystemThe Sun: The Sun The sun is the center of the Solar System. The planets and asteroids go around the sun.The Planets: The Planets There are 8 planets and Pluto. Pluto is not a planet. It is called a planetoid. The asteroid belt is between Mars and Jupiter.Order of Planets: Order of Planets Mercury Venus Earth Mars (Asteroid Belt) Jupiter Saturn Uranus Neptune (Pluto)Planet Project : google questions Planet ProjectPlanet Project Questions : Planet Project Questions 1)How big is the planet? 2)How far from the sun is the planet? 3)Are living things on the planet?Write 3 Questions: Write 3 Questions Now each group will write 3 questions you have about your planet. 1) 2) 3)10 minutes : you have 10 minutes to write your three questions 10 minutesWrite and Read Questions: Write and Read Questions Groups write your 3 questions on the board. All groups write the questions in your notebook.Slide 31: Very good! You do not have the permission to view this presentation. In order to view it, please contact the author of the presentation.
