The Sun



The sun is the most prominent object in our solar system and contains 98% of the solar system mass. You would need 109 earths to fit across the sun and the interior of the earth could hold as many a 1.3 million earths. The sun has been active for 4.6 billion years and probably will be for another 5 billion.

Layers of the Sun

The outer visible layer of the sun is called the photosphere and has a temperature of 11,000 degrees F. The chromosphere is above the photosphere and solar energy passes through on its way out of the core causing flares. The corona is the outer part of the suns atmosphere it is where clouds of glowing gas occur. It stretches far out into the earth and is only visible during a total solar eclipse.

 The Moon The moon is the earths only satellite and is the 5th largest satellite in the solar system. It is the largest moon in the solar system relative to the size of the earth, it is a quarter of the earths diameter and 1/81 its mass.

Orbit

The moon makes an orbit around the earth every 27.3 days.

 The Earth

Earth is the third planet from the sun and is the fifth densest of all eight planets in the solar system. It is home to millions of humans and is the only planet that is known to have life. It was formed 4.45 billion years ago and life appeared within the last billion years. Earth is a terrestrial planet that means it is a rocky body instead of a gas one such as jupiter.
