Our solar system consists of the sun and nine planets. Mercury is the closest planet to the sun. Mercury was named after the Roman God of Commerce and Thievery. It might have gotten its name because of the way it quickly appears and disappears from Earth’s view. Mercury is the second smallest planet in the solar system; Pluto is the only planet that is smaller. Earth’s diameter is about 7‚200‚ while tiny Mercury has less than half of that size‚ about 3‚000 miles in diameter. Mercury‚ a planet‚ is

universe also what follows? He also covered Ptolemy’s contribution‚ created a model showing the bodies of the solar system. But there was a man who did not agree with Ptolemy and his name was Nicholas Copernicus‚ he believed in a heliocentric system which pretty much means the sun is at the center of everything. Galileo Galilee and Johannes Kepler shortly have noticed other moons of many other planets in the system that proved Copernicus’ theory to be

Solar disruption theory was one of several theories that emerged before the 18th century concerning the formation of the solar system. Solar disruption theory states that the collision of the sun with another stars caused debris to be ejected from its mass and these debris eventually became the planets. This theory was later discarded for the nebula theory of solar system formation. However there are some scientists that propose that it has some merit. The big question up until the 18th century

As a tropical country‚ the Philippines has untapped vast potential of solar energy; yet in 1980’s‚ solar application is beyond the bound of possible solutions in rural‚ remote areas in the country. Thus in February 27‚ 1981‚ Federal Republic of Germany and Republic of the Philippines entered into a contract to develop applications of solar energy in the Philippines. This project was called the Philippine German Solar Energy Project (PGSEP) which was funded by the German Bundesministeruim for

Comet‚ Asteroid‚ and Meteor An asteroid and a comet are very similar‚ and yet at times they are unique and easily distinguishable from each other. An asteroid and a comet are both a small solar body system‚ rotating around the sun. An asteroid consists of rock and metal‚ and may have some organic compound. Although it is quite like the comet

the structure of the solar system and the movement of the planets. Inventions such as the telescope permitted them to see the moon’s craters‚ the canals on Mars‚ Saturn’s rings‚ and other intriguing details. This knowledge increased their curiosity about the moon‚ sun‚ and planets‚ and they longed for more information. They even dreamed of expeditions across space to encounter them first-hand. In the early years of the space program‚ lightweight batteries‚ fuel cells‚ and solar modules provided electric

The main topic is solar system processes which encompasses multiple areas of the natural sciences. Numerical simulations of solar system processes are also conducted at ground based facilities or on-board space platforms. The editor-in-chief is Rita Schulz (European Space Agency/European Space Research and Technology Centre). It is published by Elsevier.[1] Celestial mechanics is part of these studies‚ as this science includes understanding the dynamic evolution of the solar system‚ relativistic effects
