• what is the life cycle of a star bigger than the sun?

  • nebula
  • protostar
  • main sequence
  • super red giant
  • supernova
  • neutron star or black hole
• what is the life cycle of a star when it gets to a similar mass to the sun?

  • nebula
  • protostar
  • main sequence
  • red giant
  • white dwarf
  • black dwarf
• which stage of the cycle of a star are elements heavier than iron produced?

  supernova
• artificial satellites


  man made objects that orbit the planet
• planets


  orbits the stars and sun
• dwarf planets


  orbits the stars
• camets


  similar to asteroids, made of rocky material dust and ice
• moon


  natural satillite
• closer the orbit


  faster the planet moves
• further the orbit


  slower the planet moves
• what happens if the planet is at a constant speed?

  even when the planet has constant speed it will accelerate inwards so the direction changes
