Our Sun

SUN COMPARISON CHART

The sun. We couldn’t live without it. All life on earth depends on the energy that comes from the sun. It controls our climate and weather. How much do you know about this giant ball of energy in the sky?The sun is really a star. It is the closest one to earth. It is about 148 million kilometers away. The sun is the center of our solar system. All the planets revolve around it.

Although it has a diameter of about 1.3 million kilometers, the sun is only a medium star. It is known as a yellow dwarf. The sun is part of the Milky Way galaxy. Scientists believe it is just a bit older than earth, about 4.6 billion years.

There is no real surface on the sun. It is made of gas, much the same way a cloud is made of water vapor. Although a cloud looks solid against the sky, it really isn’t. You can’t touch it or rest on it. The sun is much the same way. It only looks solid against the sky as we view it from so far away.

Scientists predict that the sun will keep burning for about 4 billion years.

The sun makes up almost 99 percent of the mass of our solar system. It is so large; about a million earths would fit inside it. The sun has a mass of almost 333 thousand times the Earth’s.

We could not live on the sun. But we couldn’t live without the sun. It is a giant nuclear furnace that warms our planet. We depend on it to rise every morning and set every night- for four billion more years, at least!
