The Sun

Properties of the Sun
  • Just an average size star
  • Enormous compared to Earth
  • 110 times the diameter of the Earth
  • Mass is 745 times greater than all the planets
    put together
  • Volume it could hold more than 1 million Earths
    inside of it.

Suns Atmosphere
  • Photosphere is apparent bright yellow (400 Km
    thick)
  • Granules the millions of cells that make up the
    photosphere
  • Each one is about 1500 km across

5
What causes the surface to change?
  • The suns surface in constantly changing
  • Gases rise in the center of the granules then
    allowing the ends to sink.
  • Because of the gases moving all the time it
    constantly is moving around the granules, causing
    the surface to constantly change.

6
Sunspots
  • These occur on the photosphere
  • They are darker because of the difference in
    temperatures. (the darker the cooler)
  • They come in pairs

7
Solar Wind Magnetic Storms
  • Solar wind- the corona gives off constant stream
    of electrically charged particles
  • Avg speed 400 k/s (892,800 mph)
  • Coronal holes- huge gust of solar winds
  • These sometimes span half of the sun and may take
    months to close up
  • Solar flares- outburst of light that rise up
    suddenly in areas of sunspot activity
  • Auroras northern and southern lights (when
    solar winds blow past the Earth and particles
    interact with Earths magnetic field and upper
    atmosphere)

Suns Energy
  • Emc2.Albert Einstein
  • States that matter can be converted into energy
    and vice versa
  • The sun is mainly made up of Hydrogen
  • when 4 meet (4.030amu)and change to Helium
    (4.003 amu)
  • The difference in mass did not get lost it was
    converted into energy
