Transcript of The Sun

The sun is 3 billion years old
The sun right now is 5,778 K
On the surface it is about 10,000 F
In the core it is about 27,000,000 F
The average distance is 93,000,000 miles
At the farthest in orbit it is 94,000,000miles
Use solar filters for telescopes, use a pinhole camera, project sun onto another object
Sunspots are cool darker patches on the sun
Sunspots were discovered in 467 BCE by Anaxagoras
The release of magnetic energy from sunspots create magnetic storms on Earth
Through history, sunspot activity fluctuates
Maunder Minimum (1645-1715)
There were 64 sunspots Thursday and 61 sunspots Tuesday
Activity on the Sun
Solar flares release magnetic energy
Increase activity every 11 years
Corona is outer most layer
Free electrons
Solar wind is charged particles
Made of plasma
Cromoshphere is layer above photosphere
Mostly red in color
Photosphere is above the convection zone
Visible to us
The Make-up of the Sun
Chemicals include Hydrogen, Helium, Oxygen, Carbon, Neon, Nitrogen, Magnesium, Iron, and Silicon
These are all made in the suns core
Nuclear fusion convert hydrogen into other elements the sun might need
72% of the sun is Hydrogen 26% is Helium and the 2% is the rest of the chemicals
An obscuring of the light from one celestial body by the passage of another between it and the observer or between it and its source of illumination

Basics of the Sun
The Sun on an Atomic Level
Hydrogen converted to Helium in nuclear fusion
20,000 years for hydrogen atoms (photons) to reach surface from the core
Nuclear Fusion - atomic nuclei fuse together to form a heaver nuclei and release energy
Nuclear Fission - heavy nucleus splits to release energy

Alien's Sun
What color is your sun?
What is it powered by?
How far away is it?
Is it the only source of light/heat on your planet?
How big is it compared to your planet?
How many planets rely on it for light/heat?
How hot is it?
Have you ever been to it?
Does your sun rotate; if so how long does it take?
How many planets orbit around it?
All the hydrogen (if that's what it was fueled by) was used up and it began to expand and eventually explode
