Energy Solar System

Audrey Said:

What is the major source of energy in our solar system?

We Answered:

Nuclear energy in the sun, which is then transferred by radiation. The nuclear reactions are caused by colliding particles in the sun's core due to the massive gravity.

Daniel Said:

Why does it take less energy for a rocket to get out of the solar system than sun?

We Answered:

It has to do with the work that gravity is doing on the vessel as it travels through space. As you travel farther from an object its force of gravity gets less and less and as you travel closer the force of gravity gets greater and greater. Thus traveling back from the Sun could very likely take more energy than travel out to the edge of the solar system.

However if you merely wanted to send vessel right into the sun with no return flight, then that would be more efficient since the center of gravity in the solar system is near the sun and thus there would be less force pulling back on it and more pulling it forward then sending it out to space.

Megan Said:

Can we achieve perpetual energy threw our solar system i think so !?

We Answered:

Sorry to say, you are wrong about the gravity holding the planets at just the right place in the solar system.

It the speed that the planets orbit the sun that keeps the planets in just the right place in the solar system.

If the planets slowed down on their orbits around the sun, the planets would start moving in toward the sun, and if the planets orbits were to speed up, they would move out away from the sun.
