- Motions of the Sun Simulator
- Rises East --> sets West
- Depending on the time of year, we can use the altitude to calculate the Sun's position in the sky
- Maximum height when crossing the meridian at local noon
- Local noon
- Declination ranges between -23.5Ëš and +23.5Ëš

Composition
Core
- Extremely dense
- Source of all its energy
- Approximately 20% of the interior
- Temperature of 15 million K
Radiative Zone
- Photons carry energy and hit particles transferring energy
- How energy goes from inside --> outside
- Light from the core is transported through this zone very slowly
- High density
- Photons encounter other particles and change direction or lose some energy
Convective zone
- Hot blobs of gas moving out
- Outermost layer of the interior
