Question

why is the sun so bright ?​

Answer 1

Answer:

It's a big ball of gas accounting for 99.8 percent of the total mass of the solar system. More than a million Earths would fit inside the sun! A process called nuclear fusion converts hydrogen to helium deep in the sun's core, where temperatures hit a balmy 27 million degrees Fahrenheit (15 million degrees Celsius). Fusion creates energy that travels to the sun's surface in a journey that can take 100,000 years.

Answer 2

The Sun glows because it is a very big ball of gas, and a process called nuclear fusion is taking place in its core. Nuclear fusion occurs when one proton smashes into another proton so hard that they stick together...and release some energy as well...
