Study Notes
Solar Facts
- The Sun is a star located at the center of our solar system.
- It is primarily composed of hydrogen (about 74%) and helium (about 24%), with trace amounts of heavier elements.
Energy Production
- The main source of the Sun's energy is nuclear fusion, which occurs in its core.
- During nuclear fusion, hydrogen atoms combine to form helium, releasing an enormous amount of energy in the process.
Temperature Insights
- The approximate temperature of the Sun's core reaches around 15 million degrees Celsius (27 million degrees Fahrenheit).
- The extreme temperatures are essential for sustaining the nuclear fusion reaction.
Visible Layers
- The layer of the Sun visible to the naked eye is called the photosphere.
- The photosphere appears as a bright surface from which most of the Sun's light is emitted.
Age of the Sun
- The Sun is approximately 4.6 billion years old.
- It formed from the gravitational collapse of a region within a large molecular cloud.
