Astronomy is a very exact branch of knowledge, although many people become interested in it when they are very young. Astronomy is a thought-provoking leisure activity that can show children about the other sciences in general. Some astronomical subjects interest kids and movies like Star Wars and they serve to increase this attraction.
The Planet’s nearest neighbour is the moon. Its path around the Planet takes just over twenty-seven days to complete. Mankind has only ever set foot on the Planet and the moon. The gravity between the moon and Planet causes the tides. Its brightness in the night sky attracts many children to gather more about it and the subject of astronomy in general.
Consider Sol, our own star, the sun. The distance between our home and the sun is very generous, although it fluctuates from 91 to 94 million miles. The reason for the variance is the Planet’s elliptical orbit. If there were no sun, we wouldn’t be alive. The sun provides both light and heat to the planets. A small known fact is that the sun contains about 98% of the mass in the solar system. That is massive!
Our planet is in the galaxy called the Milky Way. Like all other galaxies it’s a very generous group of gas, dust, stars and planets. Most of the area in a galaxy is filled with nothing, only unfilled 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 nothingness.
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 part 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 lot of in rank about astronomy on the Internet that is suitable for children: it ranges from dictionaries and encyclopaedic references to programs that show the paths of the different planets, solar systems and objects right on the computer’s watch! In fact, there’s more in rank out there than a outcome could ever get through.
