Astronomy For Children.
Astronomy is a very serious branch of science, although a lot of people become interested in it when they are quite young. Astronomy is inspiring hobby that can show children about the other sciences in general. Certain astronomical subjects interest kids and movies like Star Wars and they only increase this interest.
The Earth’s nearest neighbour is the moon. Its orbit around the Earth takes just over twenty-seven days to complete. Mankind has only ever set foot on the Earth and the moon. The gravity between the moon and Earth causes the tides. Its brightness in the night sky attracts 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 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 diameter, the volume of our galaxy, is empty.
We’re situated somewhere in the neighbourhood 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 just like a pool of liquid, which is why it was given the name Milky Way. There are four types of galaxies: elliptical, lenticular, irregular and, like the Milky Way, spiral.
There is a great deal of information about astronomy that is fit 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.
