The Sun

The Sun (Sol)

I chose the sun as one of my stars because I have learned about it in school every since I was little, however, we never learned detailed information about it. We always used it as a reference point when talking about planets (ex. Earth is the third planet FROM THE SUN). I wanted to learn more about its chemical makeup and actual location in space.

History of Name: "Sun" comes from the Old English (Anglo-Saxon) word "sunne" which came from the Germanic word "sunno", both of which mean "sun".  "Sunno" came from the word "suwen" or "sawen" from the Indo-European language.  These were alternate forms of  the Indo-European word "sawel" which meant "to shine" or "the sun". 


Chemical Make Up:

Element	% of total atoms	% of total mass
Hydrogen	91.2	71.0
Helium	8.7	27.1
Oxygen	0.078	0.97
Carbon	0.043	0.40
Nitrogen	0.0088	0.096
Silicon	0.0045	0.099
Magnesium	0.0038	0.076
Neon	0.0035	0.058
Iron	0.030	0.014
Sulfur	0.015	0.040

Location:  The sun's location is unique in that each day it appears to traverse the full length of the sky from east to west. Its exact time of rising and setting differ based on Terra's (the Earth's) position in relation to the sun. Right Ascension and Declination: 0h0m0s, +0°0'0" (epoch 2000.0)
Celestial (X,Y,Z) coordinates in ly: 0, 0, 0
