Planets and Solar System Essay -- Science Astronomy Astronomical Essay

Planets and solar SystemA planet is a celestial body that revolves close to a central star and does not shine by its consume light (Grolier, 1992). The only planetary system that is cognise to man is our solar system. It is make up of baseball club planets which range in size and make-up. The nine major planets in our solar system be hydrargyrum, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto. There are also many other minor planets which are also in our solar system, but they are unimportant compared to the nine major planets. In this paper I ordain discuss the planets and how they are each unique. hectogram which is the planet that is closest to the sun is the first planet I will discuss. hydrargyrum is the smallest of the inner planets. It is speculated that the ignite from the sun made it impossible for the gases bring out to become part of the planetary formation. The surface of Mercury is extremely hot. It is al puff up-nigh 470 degrees celsius on th e surface and is thought to be even hotter at the both hot spots. These hot spots are on opposite ends of the equator. It is the heat of the surface that makes it impossible for Mercury to have any type of atmosphere. Mercury orbits the sun once every 88 days and has a true rotation period of 58.6 days. It is the closest planet to the sun and therefore orbits windy than any other planet (Thompson/Turk, 542, 1993). It is said that Mercury rotates three time for every two trips around the sun, so that during every alternate perihelon transition the same face points directly at the sun. Geologically, the most remarkable features of Mercury are compressional cliffs or faults, just the sort of wrinkles that might form in the crust if the interior of the planet shrank slightly (Morrison, 74, 1993). It is speculated that it was the solidification of Mercurys metallic nucleus that caused this global shrinkage. Mercury is also . . . enriched in metal or miserable of rock (Mor rison, 74, 1993). It is also believed that some of the inner core of Mercury is static in a fluid state. Scientists also believe that Mercurys surface is made partially of silicate rock. The best way to describe Mercury is, . . . small, heavily cratered and nigh (Morrison, 71, 1993). Venus is the second closest planet to the sun and is said to . . . most closely resemble Earth in size, density, and... ...n see the planets of most sizeableness are the ones closest to the sun and Earth. Little is kn take in about the furthest off planets therefore it is hard to give them full recognition. Much is known about Mercury, Venus, Earth, Mars, Jupiter and Saturn. The other three planets are not as well known as these six are. Whether more planetary systems exist doesnt authentically matter. There are still plenty of things we dont understand about our own solar system. Scientists will have their work cut out for them in the future. Each and every planet has distinct differences and that helps show us how real great God is. The planets will never fully be mute and will always be a great topic of discussion. work Sited Cattermole, P. (1995). Earth and Other Planets. New York Oxford University Press.
