The Solar System‚ where the planet Earth belongs‚ is formed by: a start known as the sun‚ four inner planets‚ Mercury‚ Venus‚ Earth and Mars‚ and five outer planets‚ Jupiter‚ Saturn‚ Uranus‚ Neptune and Pluto‚ over 60 satellites or moons‚ more than 5‚000 asteroids‚ numerous comets‚ and smaller interplanetary dust and debris (“Astronomy n.pag). The way that all this elements of the Solar System interact and move around the Sun seems to be perfectly synchronized but‚ how did it began? What was it

URANUS MRS. LANE’S SCIENCE CLASS AMIL JONES MAY 22‚ 2013 PERIOD 5 Uranus is one of the outer planets which we call gas giants and Uranus is also the seventh planet from the sun which was discovered in 1781 by an astronomer named William Herschel. Uranus was the first planet to be discovered in Modern times. Uranus is named after a Greek god of the sky in Latin. Before Uranus was discovered it was thought to be a comet but it was not fuzzy looking so it couldn’t be. It’s so far from the

provide clues: (1) The Sun‚ planets‚ and large moons generally rotate and orbit in a very organized way. (2) With the exception of Pluto‚ the planets divide clearly into two groups: terrestrial and jovian. (3) The solar system contains huge numbers of asteroids and comets. (4) There are some notable exceptions to these general patterns. 4. What are the basic differences between the "terrestrial and jovian" planets? Which planets fall into each group? Terrestrial - four planets of the inner solar system:

Of the many objects that orbit the Sun‚ most of the mass is contained within eight relatively solitary planets whose orbits are almost circular and lie within a nearly flat disc called the ecliptic plane. The four smaller inner planets‚ Mercury‚ Venus‚ Earth and Mars‚ also called the terrestrial planets‚ are primarily composed of rock and metal. The four outer planets‚ the gas giants‚ are substantially more massive than the terrestrials. The two

No water or geology the two prerequisites have been found. According to Potomac institute for policy studies‚ the Mars exploration is the search for the significance of existence. If that is true‚ why carry on spending millions for discoveries of a red planet among a lot of red dirt. Mars exploration being funded millions is unnecessary‚ it has already

Exist There are several different meanings to the word “alien.” An alien could be a resident born or belonging to a different country‚ a foreigner‚ a person who has been excluded from something‚ or a creature from outer space (extraterrestrial). For this argument‚ a creature from outer space would be the appropriate definition. Many believe extraterrestrials do exist. Many even claim to have seen aircrafts belonging to these extraterrestrials. There have been thousands of “sightings” of unidentified

Satellites and probes have provided valuable information in many fields such as exploration of other planets‚ GPS systems‚ and global communication. Recently NASA has explored the topic of near-earth objects and they are currently trying to track down potential life threatening asteroids. Scientist’s inability to foresee near Earth objects poses an extremely
