Creation Day 2: How God Separated the Mayim
The sun, o ur nearest star, was created approximately 9.2 billion years after God declared , "Let there be light." Here are some interesting facts about our closest star : • More than half the stars found in the Milky Way are older and more massive than our 4.6-billion-year-old yellow-dwarf star called the sun.
• The diagram above, called the Hertzsprung-Russell or HR diagram, plots the luminosity (brightness) of stars on Y axis and temperature of stars on the X axis. The largest, hottest and brightest stars are at the top of the diagram. The smallest, coolest and dimmest stars at the bottom. Blue stars are the youngest and hottest stars. Red stars are the oldest and coolest. Our Sun is an average yellow star and is near the middle of the HR diagram. • The Sun is classified a main sequence star with a surface temperature of 5,000 degrees C /9,000 degrees F. • The temperature at the Sun’s core is 15 million degrees C. The sun's energy is generated at its core by nuclear fusion, as Hydrogen atoms are fused into Helium. Because hot objects generally expand, the Sun would explode like a giant bomb if it weren’t for its enormous gravitational force. • T he Sun is halfway through its stellar life-cycle. At 4.6 billion years old, the Sun has burned off around half of its hydrogen stores and has enough left to continue burning (fusing hydrogen) for another 5 billion years.
