Astronomy can be a life long pursuit and as with many things, even very serious things, people often become interested at an early age. This exciting science can provide hours of study, which is why astronomy is popular with children and their parents. For children, many parts of astronomy are magical and thus a huge draw. Movies like Star Wars only serve to increase this attraction.
Our only natural satellite is called the moon. Its path around the Earth takes just over twenty seven days to complete. Man's knowledge being what it is and because the moon is so close, it is the only space object that mankind has ever set foot on, except for the Earth of course. The effects of gravity between the moon and Earth causes the tides. The moon is one of the first objects that sparks a child's interest in astronomy because it can be clearly seen with the human eye.
Then there's our sun. Earth is quite far from the sun. The distance fluctuates between about 91 million miles and about 94 million miles, although these measurements are not completely accurate. They are inaccurate measurements, because the Earth orbits the sun in an uneven ellipse. Life on Earth is only possible because of the sun, because it provides us with important elements such as light and heat. It is not a well-known fact that the sun contains about 98% of all the mass available in the solar system. Think about how small a person is compared to that - it is truly imponderable!
We live in the galaxy called the Milky Way. Like all other galaxies it's a collection of gas, dust, stars and planets. Most of the area in a galaxy is filled with nothing, just empty space. That means that most of its volume, 3,000 light years high by 100,000 light years wide, the size of our galaxy, is empty. We're somewhere in the neighborhood of 30,000 light years from the central core of our galaxy. The nothingness is broken up by over 100 billion stars. In fact the galaxy was named for the thick group of stars in the main portion of it. It looks like a pool of liquid, thus the name Milky Way. There are four types of galaxies: elliptical, lenticular, irregular and, like the Milky Way, spiral.
You can find a wealth of resources concerning astronomy for teens on the world wide web. Kids could spend hours wrapped in detailed 3D representations of the universe around us. - 15437
