The Solar System Essay -- Astronomy Plantes Stars Galaxy Essays

The Solar SystemWhat be planets? Planets are kinda the likes of asteroid around the sun. There are nine planets in the solar system, Mercury, Venus, worldly concern ( Our planet ), Mars, Jupiter, Saturn,Uranus, Neptune, and Pluto. The Terrestrial PlanetsThe cislunar planets are the four innermost planets in the solar system, Mercury, Venus, Earth and Mars. They are called terrestrial because they have a compact, rocky surface like the Earths. The planets, Venus, Earth, and Mars have significant atmospheres period Mercury has almost n ane. The following diagram shows the approximate distance of the terrestrial planets to the Sun. The SunThe Sun is the most prominent feature in our solar system. It is the largest object and contains approximately 98% of the total solar system press. unrivalled hundred and nine Earths would be required to fit across the Suns disk, and its midland could hold over 1.3 million Earths. The Suns outer visible layer is called the photosphere and has a temperature of 6,000C (11,000F). This layer has a mottled appearance due to the tumultuous eruptions of energy at the surface. Solar energy is created deep within the effect of the Sun. It is here that the temperature (15,000,000 C 27,000,000 F) and insisting (340 billion times Earths air pressure at sea level) is so intense that nuclear responses take place. This reaction causes four pro stacks or hydrogen nuclei to fuse together to form one alpha particle or helium nucleus. The alpha particle is near .7 percent less massive than the four protons. The difference in mass is expelled as energy and is carried to the surface of the Sun, through a process know as convection, where it is released as light and heat. Energy generated in the Suns core takes a million years to reach its surface. Every second 700 million tons of hydrogen are converted into helium ashes. In the process 5 million tons of pure energy is released therefore, as time goes on the Sun is becoming lighter.The c hromosphere is above the photosphere. Solar energy passes through this neck of the woods on its way out from the center of the Sun. Faculae and flares arise in the chromosphere. Faculae are bright luminous hydrogen clouds which form above regions where sunspots are virtually to form. Flares are bright filaments of hot gas emerging from sunspot regions. Sunspots are dark depressions on the photosphere with a typical temp... ...s evaporate. The evaporated molecules boil off and look small solid particles with them, forming the comets coma of gas and dust. When the nucleus is frozen, it can be seen only by reflected sunlight. However, when a coma develops, dust reflects still more than sunlight, and gas in the coma absorbs invisible radiation syndrome and begins to fluoresce. As the comet absorbs ultraviolet light, chemical processes release hydrogen, which escapes the comets gravity, and forms a hydrogen envelope. This envelope cannot be seen from Earth because its light is abs orbed by our atmosphere, but it has been detected by spacecraft. The Suns radiation pressure and solar wind accelerate materials away from the comets head at differing velocities according to the size and mass of the materials. Thus, relatively massive dust white tie and tails are accelerated slowly and tend to be curved. The ion tail is a lot less massive, and is accelerated so greatly that it appears as a near straight line extending away from the comet opposite the Sun. The following view of Comet watt shows two distinct tails. The thin blue plasma tail is make up of gases and the broad white tail is made up of microscopic dust particles.
