How does the sun system work?

The Sun. The sun’s gravity pulls the planet toward the sun, which changes the straight line of direction into a curve. This keeps the planet moving in an orbit around the sun. Because of the sun’s gravitational pull, all the planets in our solar system orbit around it.

Why does the sun not burn itself out?

The Sun does not “burn”, like we think of logs in a fire or paper burning. The Sun glows because it is a very big ball of gas, and a process called nuclear fusion is taking place in its core. Hydrogen really doesn’t burn, it fuses, into helium. So no oxygen is required!

Does the Sun do any work on Earth?

The Sun itself is not a good place for living things, with its hot, energetic mix of gases and plasma. But the Sun has made life on Earth possible , providing warmth as well as energy that organisms like plants use to form the basis of many food chains.

Why is the Sun important to Earth?

The sun is important to Earth because it warms the seas, generates weather patterns, stirs the atmosphere and provides energy to growing plants. The plants are responsible for providing oxygen and food for life to exist on Earth, according to the U.S. National Aeronautics and Space Administration. The sun is more…

What would Earth be like without the Sun?

The answer is No, the Earth would not remain in any recognizable form without the Sun. There would still be a husk of a dead planet with a small amount of energy coming from the residual heat of the core which might be able to sustain chemosynthetic life in small colonies.

Will the Sun ever burn itself out?

Yes, the sun will eventually burn out. But not for a long, long time. The sun has used up about half of its hydrogen fuel in the last 4.6 billion years, since its birth. It still has enough hydrogen to last about another 5 billion years.
