Temperature Conversion from Celsius & Kelvin
Sun’s surface temperature is approximately: 5,800 K
Temperature at the Suns Core:
The visible region of the sun is called the Photosphere
The Corona stretches for millions of miles out into space, it is the outer layer of the sun’s atmosphere
Power output from the Sun in Watts: 4.0 x 10^26 W
Solar Constant: amount of "insolation" reaching the top of the earth’s atmosphere about: 1360 W/m^2
Solar Azimuth is the angle of the Sun from True South
Colorado Springs GPS address:
Aurora Borealis
Aurora Australis
Earth's Precession (Tilt)
Albedo
Perihelion is when the Earth is at its closest to the Sun
Aphelion is when the Earth is at its farthest from the Sun
Summer Solstice

Location Tropic of Cancer
Location Tropic of Capricorn
Equator
LAT. & LONG. North Pole
LAT. & LONG. Arctic Circle
LAT. & LONG. Antarctic Circle
LAT. & LONG. South Pole
Earth is divided into: 24 longitudinal time zones
Mass of the Sun: 1.99 x 10^30 kg
Mass of the Earth: 5.97 x 10^24 kg
Radius of the Earth:
Atmospheric Pressure on Earth @ Sea Level = 14.7 lb/sq. in. or 1 Atmosphere (Atm)
Speed of Light "c": 3.0 x 10^8 m/s
Electromagnetic Radiation
a. Particles (photons)
b. Waves
Energy of a photon is related to the frequency of the wave: e = (h) * (f)
Frequency of a wave is related to its wavelength: f = c / wavelength
Luminosity: amount of energy an objects radiates each second
Star's Luminosity measures how fast it consumes its fuel
Electro-Magnetic radiation to which the human eye is sensitive to is called the: Visible Spectrum
An atom in an excited state usually decays (de-excites) rapidly to a lower state by the emission of a photon
White light is the addition of various wavelengths of visible light
