The Sun, which is also called Sol, is estimated to be 4.6 billion years old with up to five billion years left in its life. It is currently in its yellow dwarf phase of life. It is located in the Milky Way galaxy in a spiral arm known as the Orion Arm. The Sun orbits the center of the galaxy at a speed of 720,000 kilometers per hour, but it takes 230 million years to make a full orbit. It has a mass that is estimated to be 1.988×1030 kg, which is 330,000 times the mass of Earth. This allows it to have a strong enough gravitational pull to have eight distant planets orbit around it. The diameter of the Sun is estimated to be 696,342±65 kilometers, which is 109 times the diameter of Earth. The average density of the sun is 1.408 g/cm3, which is only a quarter of the density on Earth.The temperature of the sun is averaged around 5 million degrees celsius. 73% of the Sun is made of Hydrogen and 25% of the Sun is made of Helium. The rest of the sun is made up of other elements, such as carbon and iron. …show more content…
The core of the sun is the innermost layer. This is the hottest place in the sun, reaching temperatures of over 15 million celsius. This is the layer that produces all of the energy in the sun. The radiation zone is the middle layer. This is the most dense place in the solar system. Here, energy created from the core is transferred through radiation. Because of how dense the radiation zone is, it can take energy 100,000 years to travel through it. The outermost layer is the convection zone. Like its name suggests, energy here is transferred through convection. This is the coolest layer of the sun, reaching only two million degrees
