Astronomy For Kids.
Astronomy is a very exact science, although many people become interested in it when they are quite young. Astronomy is inspiring hobby that can teach children about the sciences in general. A number of astronomical subjects inspire kids and movies like Star Wars and they only serve to increase this attraction.
The Earth’s nearest neighbour is the moon. Its path around the Earth takes just over twenty-seven days to complete. Mankind has only ever walked on the Earth and the moon. The gravity between the moon and Earth is responsible for the tides. Its brightness in the night sky encourages many children to learn more about it and the subject of astronomy in general.
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 is 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 holds about 98% of all the mass available in the solar system. Think about how tiny 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 diameter, the size of our galaxy, is empty.
The Earth is situated somewhere in the vicinity of 30,000 light years from the central core of our galaxy. The emptiness is broken up by over 100 billion stars. In fact, the galaxy was named for the thick group of stars in the main section of it.
It resembles a pool of liquid, which is why it was called the Milky Way. There are four kinds of galaxies: elliptical, lenticular, irregular and, like the Milky Way, spiral.
There is a lot of information about astronomy that is suitable for children on the Internet: from dictionaries and encyclopaedic references to programs that show different planets, solar systems and objects right on the computer’s monitor! In fact, there’s more information than a child could ever read.
