"Jupiter is the largest planet in the Solar System and there is a large red spot on its surface which is a storm that has been taking place on the planet for ... uneven shape. Solar System The Solar System consists of the planets, dwarf planets, moons, asteroids, centaurs, comets and other minor planets. To put it briefly, the Solar System consists of the planets which revolve around the Sun. This is because the Sun has a very powerful gravity and attracts the celestial objects towards it. Due to this reason, these objects don't have a permanent place in the Solar System and keep revolving around the parent star. According to a well-known theory, the Solar System was created approximately 4.6 billion years ago from dust and gas due to a giant molecular cloud collapse. Immediately after this collapse, the dust particles and the gas vapor started to move in a circular motion. This is when a star formed between the circular cloud of dust and gas. The star in the centre burst into flames and due to the sudden ignition, the solar winds pushed the remainder of the dust and gas outwards. This star is known as the Sun today. The remaining dust and gas came together and formed small clumps at a distance from the Sun. Nowadays these small clumps are known as the planets, moons, comets, and asteroids. Since human beings didn't exist then, nobody is sure about how exactly the Solar System evolved.

Mars The Bringer of War Mars is the fourth planet from the Sun and the seventh largest: orbit : 227,940,000 km (1.52 AU ) from Sun diameter : 6,794 km mass : 6.4219e23 kg Mars (Greek: Ares ) is the god of War. The planet probably got this name due to its red color; Mars is sometimes referred to as the Red Planet. (An interesting side note: the Roman god Mars was a god of agriculture before becoming associated with the Greek Ares; those in favor of colonizing and terraforming Mars may prefer this symbolism.) The name of the month March derives from Mars. Mars has been known since prehistoric times. Of course, it has been extensively studied with ground-based observatories . But even very large telescopes find Mars a difficult target, it's just too small. It is still a favorite of science fiction writers as the most favorable place in the Solar System (other than Earth!) for human habitation. But the famous "canals" "seen" by Lowell and others were, unfortunately, just as imaginary as Barsoomian princesses. Viking 2 Landing Site Pathfinder Landing Site The first spacecraft to visit Mars was Mariner 4 in 1965. Several others followed including

The discovery of Eris, the 10th planet largest known dwarf planet Discovery images of the dwarf planet Eris. The three images were taken 1 1/2 hours apart on the night of October 21st, 2003. The Eris can be seen very slowly moving across the sky over the course of 3 hours. Eris is 27% more massive than Pluto 2003 UB313 is now officially Eris! Eris, the largest dwarf planet known, was discovered in an ongoing survey at Palomar Observatory's Samuel Oschin telescope by astronomers Mike Brown (Caltech), Chad Trujillo (Gemini Observatory), and David Rabinowitz (Yale University). We officially suggested the name on 6 September 2006, and it was accepted and announced on 13 September 2006. In Greek mythology, Eris is the goddess of warfare and strife. She stirs up jealousy and envy to cause fighting and anger among men. At the wedding of Peleus and Thetis, the parents of the Greek hero Achilles, all the gods with the exception of Eris were invited, and, enraged at her exclusion, she spitefully caused a quarrel among the goddesses that led to the Trojan war. In the astronomical world, Eris s tirred up a great deal of trouble among the international astronomical community when the question of its proper designation led to a raucous meeting of the IAU in Prague. At the end of the conference, IAU members voted to demote Pluto and Eris to dwarf-planet status, leaving the solar system with only

Observing during the day can be a decided advantage. The planet's brightness will be subdued enough to not dazzle the eye. The planet is also high in the sky away from the denser portion of Earth's atmosphere. CHOOSE THIS PROJECT ONLY IF YOU HAVE A TELESCOPE PROPERLY POLAR ALIGNED AND CAPABLE OF LOCATING THE PLANET WITHOUT ENDANGERING EITHER THE INSTRUMENT OR YOURSELF - USE EXTREME CAUTION - EYE DAMAGE COULD RESULT. In your favorite astronomy periodical note the right ascension and declination of the Sun and Venus. Center the Sun in your telescope by projecting the image onto a screen or the ground. Set your setting circles to that of the Sun and turn on your drive. Now offset the appropriate amounts to arrive at the coordinates for Venus. (Make sure your focus is correct, an out-of-focus planet may be impossible to see.) You should be able to see Venus in your finder scope. An orange filter in your main eyepiece will help increase image contrast. Describe your experience.

The Sun Sol Our Sun is a normal main-sequence star, one of more than 100 billion stars in our galaxy. diameter km mass kg ... K (surface) 15,600,000 K (core) The Sun is by far the largest object in the solar system. It contains more than 99.8% of the total mass of the Solar System ( Jupiter contains most of the rest). It is often said that the Sun is an "ordinary" star. That's true in the sense that there are many others similar to it. But there are many more smaller stars than larger ones; the Sun is in the top 10% by mass. The median size of stars in our galaxy is probably less than half the mass of the Sun. The Sun is personified in many mythologies: the Greeks called it Helios and the Romans called it Sol The Sun is, at present, about 70% hydrogen and 28% helium by mass everything else (" metals ") amounts to less than 2%. This changes slowly over time as the Sun converts hydrogen to helium in its core. The outer layers of the Sun exhibit differential rotation : at the equator the surface rotates once every 25.4 days; near the poles it's as much as 36 days. This odd behavior is due to the fact that the Sun is not a solid body like the Earth. Similar effects are seen in the

94. Quaoar Frequently asked questions. http://www.chadtrujillo.com/quaoar/

Frequently Asked Questions About Quaoar What is Quaoar? Quaoar is a newly discovered Kuiper Belt object, found in June 2002 by Chad Trujillo and Mike Brown at Caltech in Pasadena. It's the largest Kuiper Belt object currently known, half the diameter of Pluto (about 1/8 the volume), and 1.6 billion kilometers (1 billion miles) further away than Pluto. How big is Quaoar? Quaoar is about 1250 km in diameter, roughly the size of Pluto's moon Charon. Nothing larger has been found in our solar system since Pluto was discovered in 1930 (and Pluto's moon Charon in 1978). It's huge, in fact, if you took the 50,000 numbered asteroids and put them together, it would be about the same volume as Quaoar. Here's a picture of Quaoar compared to some other Solar System objects. (NASA and A. Feild (STSci) Is Quaoar a Planet? We don't think so. It's about half the size of Pluto and further away, but there are other big objects out there, too. Varuna (900 km in diameter) and 2002 AW197 (also 900 km in diameter) are two of the biggest Kuiper Belt Objects, and they are not considered "planets" either. There are about 600 known Kuiper Belt Objects, most of which are only about 100 km in diameter, and all of which were discovered since 1992 by different scientists who have been looking for them. It's similar to the asteroid belt, but beyond Neptune and contains maybe 100 times more material. You can read more about the Kuiper Belt at the Kuiper Belt Homepage . Note that the Kuiper Belt is also called the Edgeworth-Kuiper Belt and the trans-Neptunian Belt. We think we should be able to find 5 - 10 more of these really big Kuiper Belt Objects over the next couple of years, including perhaps a couple "super-Plutos".

95. PLANETS Formation Process Article from a book by Angel Fernando Vitoria. http://www.planetsformation.netii.net/

PLANETS FORMATION PLANETARY FORMATION PROCESS ESPAŅOL Our starting point to planetary formation and solar systems formation process are the stellar systems. STELLAR SYSTEMS FORMATION Solar systems and stellar systems both have very similar structures. Typically, stellar systems have one or more central masses (normally one) and a number of minor masses, mainly dwarf stars, orbiting around the center in a discal or plane fashion. Similarly, solar systems also have a central main star (the sun) and a number of minor masses (the planets) orbiting around the central sun, also in a discal or plane fashion. TRANSFORMATION PROCESS FROM YELLOW DWARF TO PLANET. When it comes to planetary formation, it is important to consider the size, the mass and the structural characteristics of planets themselves as compared with the size, mass and structural characteristics of dwarf stars orbiting in stellar systems as their conformation is very similar. A very important point is that both, dwarf stars and planets, do have a nucleus and a spherical structure. In the planets formation process, the nucleus of the original minor stars orbiting (yellow dwarfs) becomes the nucleus of the new planets, enveloped and protected by the cortex. Hubble S. T. Photo.

96. Venus  L  Venus Facts, Pictures And Information. From The Nine Planets. http://www.nineplanets.org/venus.html

Venus The Bringer of Peace Venus is the second planet from the Sun and the sixth largest. Venus' orbit is the most nearly circular of that of any planet, with an eccentricity of less than 1%. orbit : 108,200,000 km (0.72 AU ) from Sun diameter : 12,103.6 km mass : 4.869e24 kg Venus (Greek: Aphrodite ; Babylonian: Ishtar) is the goddess of love and beauty. The planet is so named probably because it is the brightest of the planets known to the ancients. (With a few exceptions, the surface features on Venus are named for female figures.) Venus has been known since prehistoric times. It is the brightest object in the sky except for the Sun and the Moon. Like Mercury , it was popularly thought to be two separate bodies: Eosphorus as the morning star and Hesperus as the evening star , but the Greek astronomers knew better. (Venus's apparition as the morning star is also sometimes called Lucifer.) Since Venus is an inferior planet, it shows

Both the relative size and spacing of the planets are demonstrated in this outdoor exercise, using a mere peppercorn to represent the size of the Earth. Guy Ottewell has kindly given permission for this electronic presentation of The Thousand-Yard Model; his exercise is presented in its original form, indexed with a few anchors to help you find you way around the large file. We also include a catalog describing several Ottewell publications. Image of the planets courtesy of NASA Introduction Can you picture the dimensions of the solar system? Probably not, for they are of an order so amazing that it is difficult either to realize or to show them. You may have seen a diagram of the Sun and planets, in a book. Or you may have seen a revolving model of the kind called an orrery (because the first was built for an Earl of Orrery in 1715). But even the largest of such modelssuch as those that cover the ceilings of the Hayden Planetarium in New York and the Morehead Planetarium at Chapel Hill-are far too small. They omit the three outermost planets, yet still cannot show the remaining ones far enough apart.
