## Extract of sample Intro to Astronmy

The sun and the moon were believed to move eastwards in an orderly fashion. In 200 AD, astronomers believed that planets moved round the earth in small circles called the epicycle. The Heliocentric model later explained that all planets including the sun revolved around the sun. This model also explained that the retrograde motion of planets did so as the earth which moves faster than the other planets overtook the other planets. Other planets are categorized as superior or inferior to the earth. Time that is able to elapse between the configurations that are identical and consecutive is known as the synodic period. It was Copernicus who determined the sidereal period of other planets. He was also able to know the distance between the planets and the sun. Kepler was able to come up with a law that stated that every planet has an orbit that about the sun know as an ellipse. He also came up with the semi major axis. This happens to be the distance between the planets and the sun. The measure of the deviation from the perfect circle is known as the eccentricity. Kepler had three laws to explain the motion of planets and this was a major achievement in the field of astronomy. Galileo was able to discover a lot more with the aid of a telescope. He was able to know that the earth was not at the centre of the universe. With his telescope, he was able to know that the earth was not at the centre of the universe and that the earth was just like any other planet moving around the sun. Isaac Newton later came and introduced three laws. Inertia, force and action and reaction. He was also able to come up with the laws of the universal gravitation. The law of gravitation states that two bodies attract each other with a force directly proportional to each and every mass of the two bodies. This force is also inversely proportional to the square of the distance between them. Using the law of gravitation, Kepler’s three laws can be summed up. Newton’s was able to note that every object moving around the sun was able to be in a family of curves known as the conic curves. Chapter 7: Our solar system Our solar system is made up of the sun, the eight planets and some terrestrial bodies all revolving around the sun. There are three dwarf planets that are known to orbit the sun. All the eight planets have a total of 166 moons that orbit around them. There are four inner planets and other four outer planets with respect to the sun. Mercury is the closest planet to the followed by Venus and then our planet earth. Mars is the fourth planet from the sun and some scientist argue that there is life in mars but it is not confirmed yet. Saturn has a ring around it and is believed to be surrounded by neon gas. The temperature in mars and other outer planets is so low that it cannot support life while the temperature of the Venus and mercury are too high to support any life. Every planet moves around the sun and they both take different years to move around the sun. Our sun is a collection of gases that burn up to provide the light and heat energy that is distributed to the other planets as well as the earth. It is through the sun that life is able to exist (Freedman 45). Chapter 8: origin of the solar system The formation of the solar system can be traced back to the formation of matter. Nucleosynthesis is the process through which all the formation blocks of the early universe ...Show more
