The solar system consists of the Sun and 9 planets revolving around it in different orbits. The statistics of the sun and the planets are given below : SUN Age : About 5 Billion years Distance : 149.8 Million Kms Diameter : 1‚38‚400 Kms. Photosphere temperature : 5‚770 K Core temperature : 150‚000‚000 K Absolute visual magnitude : 4.75 Rotation (as seen from the earth at the equator) : 25.38 days Rotation (near the poles) : 33 days The sun consists of 71% of Hydrogen‚ 26.5% Helium and

Shoemaker is a comet that hit the planet Jupiter in July of 1994. It was discovered by three expert comet detectors‚ Eugene and Carolyn Shoemaker‚ and David Levy‚ in 1992. The comet originated its name by its discoverers the “Shoemaker- Levy 9: Comet”. As information came it they started to realize that the comet had been orbiting Jupiter and not the Sun itself. They discovered that the comet might have even been orbiting the planet as late as the year 1966. The impacts ended up being a multi-day

A Comparison of the Planets in the Sol System Shaun J. Sci350 December 19‚ 2004 Introduction Beginning Mercury‚ this paper will compare the nine planets and major moons of our solar system and describe their individual characteristics. At the end of this discussion‚ the habitability factor of these different worlds will be discussed as compared to that of the Earth ’s. A Brief History of the Sol System By radiocarbon dating meteorites‚ we know that roughly 4.6 billion

Why do the planets have different colours? The answer is that the planets are different colors because they are made of different materials. Planets have the colours that they have because of what they are made of and how their surfaces or atmospheres reflect and absorb sunlight. Mercury has a dark grey‚ rocky surface which is covered with a thick layer of dust. The surface is thought to be made up of igneous silicate rocks and dust. Venus is entirely covered with a thick carbon dioxide atmosphere

The word planet is derived from the ancient Greek word planetes‚ or “wanderers.” Though the visible planets of that time did appear to be wandering in the sky‚ the science of Astronomy has broadened this term as well as our understanding of what‚ in fact a planet is. By modern definition‚ “planet” is described as a celestial body other than a star‚ which orbits a star. Our Solar System orbits the center of our home galaxy‚ the Milky Way‚ and has a rich and varied structure. It consists of the

The “Planet” Pluto was discovered by scientist in 1930. Even then‚ there was argument over whether this little ball of ice should be considered a planet. It was decided it should‚ mainly because since the gravity of the eighth planet‚ Neptune‚ was found because it was tugging on the seventh planet‚ Uranus‚ and then Pluto was found when its gravity tugged on the orbit of Neptune. Pluto was just a continuation in the time-tested practice of discovering the existence of planets from the behavior of

that is known to man is our solar system. It is made up of nine planets. The nine major planets in our solar system are Mercury‚ 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. Mercury‚ which is the planet that is closest to the sun‚ is the first and smallest of the inner planets. It is speculated that the heat from the sun made it impossible

The Giant planets Lesson 8.8 Introduction: Gas giants fall into different categories. So-called “traditional” gas giants include Jupiter. Jupiter is such a classic example of a gas giant that gas giants are often referred to as Jovian planets despite the fact that some gas giants ‚ice giants for instance are very different from Jupiter. Traditional gas giants have high levels of hydrogen and helium. Another category of gas giants is ice giants. Ice giants are also composed of small amounts

My friend Sydney‚ also a Ravenclaw‚ and I planned a planetary viewing for November sixteenth. We planned to go to the top of the astronomy tower‚ and catch a glimpse of the three planets we had learned could be seen in late November‚ Venus‚ Mars‚ and Jupiter. We both had passes from professor Turing‚ so we were sure we wouldn’t get caught by Filch for being out of bed. But then again‚ Filch is a bit of an idiot. We headed up to the top of the astronomy tower‚ glancing at the lunar chart Professor
