Nebular Theory (Stars (Supernova (a star only has iron left (gravity will…

- - - - hydrogen
      - helium
      - releases radiation or energy
  - - - fuses helium
      - into heavier elements
        
        oxygen
        
        carbon
    - - cooler/larger star
      - red in color
  - - - uses its carbon
        
        heavier elements
        
        star will fail
      - gas expands
        
        away from star
        
        leaves behind
        
        glowing carbon core
        
        white dwarf
  - - - loses brightness
      - becomes a black dwarf
  - - - 10 times bigger
      - more massive then our sun
  - - - it expands
      - make all kinds of elements
        
        until it forms
        
        iron
  - - - gravity will collapse it
      - until it explodes
    - - core remains
      - if star is 4 times the size of the sun
        
        becomes a neutron star
        
        it's very small
  - - - the core will collapse
      - into a black hole
    - - supermassive star
      - gravity is so strong
        
        nothing can escape
        
        not even light
- - - - leftover hydrogen
      - leftover helium
    - - remains
      - collapsed stars
  - - - gas
      - dust
    - - rotates
      - forms a disk
  - - - dust clumps together
      - forms larger clumps
        
        Large clumps attract clumps
        
        clumps form
        
        planets
        
        moons
        
        solar systems
- - - - Smallest Planet
      - No moons
      - closest to the sun
    - - No moons
      - greenhouse effect
      - atmosphere of CO 2
    - - One moon
      - contains life
      - has liquid water
    - - two moons
        
        Phobos
        
        Deimos
      - Largest volcano in the solar system
      - half the size of earth
  - - - largest planet
      - 53 confirmed moons
      - 16 unconfirmed
    - - 53 confirmed moons
      - 8 unconfirmed
      - Rings of dust, rocks, ice
    - - 27 moons
      - methane gives blue appearance
      - rotates sideways
    - - 13 confirmed moons
      - 1 unconfirmed
      - dark spots are massive storms
