Now, while in this solar system, it is the biggest structure, it is just average in size when you look at other stars elsewhere in space. For example, the star Betelgeuse is nearly 700 times larger than the sun. When it comes to brightness, it is nearly 14,000 times brighter.

Fun Facts About the Sun

The sun is a type of star and it is located approximately 93 million miles from Earth. Its energy travels outward. The core of this start is made up of different dense and hot gases. The temperature is approximately 27 million degrees Fahrenheit.

You can see that the sun is absolutely massive, especially compared to Earth. Compared to the moon associated with Earth that comes in at 2,159 miles in diameter, the sun is certainly one of the largest structures that you can see from where you are on Earth.
