The Mighty Sun, Stellar Powerhouse Illuminating the Solar System and Nurturing Life on Earth

The Sun was born nearly five billion years ago and still has quite a long time to live. The diameter of the sun is about 864,950 miles making the sun 109 times bigger than Earth. It also is 333,000 times heavier than our planet.

The sun has multiple layers that serve different purposes. The Sun's core is the source of its energy and is extremely hot. The surface of the sun is named the photosphere, which produces light and heat for planets. The corona is the largest outer layer and has solar winds that reach Earth. However, these solar winds are blocked because of Earth’s magnetic field.

The surface of the Sun can develop dark spots. Violent and rapid solar flares can cause eruptions near sunspots; these flares release magnetic energy. Another feature of the sun is the red loops around the atmosphere called prominences. These are large clouds of gas that extend outward around the Sun's atmosphere. Geomagnetic storms are caused by solar flares that can damage satellites and radio transmissions.

The temperature of the Sun’s surface is 10,000 degrees Fahrenheit and the core temperature can rise to 27 million degrees Fahrenheit. Earth is about 93 million miles away from the Sun, making the time it takes for sunlight to reach our planet only eight minutes.

The Sun is an important component of the solar system that allows for life on Earth. It is fascinating to learn about the sun and how its various components impact its surroundings.
