Terrestrial and Jovian Planets - Terrestrial and Jovian Planets Our solar system contains nine planets, which are broken down into 2 classifications known as terrestrial planets and jovian planets. The terrestrial planets are composed primarily of rock and metal. They also generally have high densities, slow rotation, solid surfaces, no rings, and few satellites. These planets include Mercury, Venus, Earth, and Mars. On the other hand, the jovian planets are composed primarily of hydrogen and helium. They generally have low densities, rapid rotation, deep atmospheres, rings, and numerous satellites....   [tags: Planets Solar System Science Essays]

Extrasolar Planets - Humans have longed to believe in extrasolar planets, as surely there have to be planets elsewhere in the universe. Claims of supposedly discovered extrasolar planets can be dated back to 1855 when Captain S. W. Jacobs from the Madras observatory, claimed that he had discovered a planet orbiting a binary system (Jacobs 1855), all the way up until 1991 when a team of astronomers announced then retracted the alleged discovery of an extrasolar planet around a pulsar star (Lyne and Bailes 1992). Planets are extremely hard to detect as they are a very faint light source and the light from its parent star is much brighter and essentially blocks out light from a planet (Winters 1996)....   [tags: Astronomy]

Hycn: Encounter On The Dead Planet - A smile flickered across her face as she realized why she agreed to come along with him. She’d agreed because it was an excuse to fly her anti-gravity fighter craft. She didn’t give a damn about exploring dead worlds and wandering planets. She wasn’t the touring kind; there was nothing interesting in exploring dead worlds. Not for her anyway. There definitely wasn’t anything worth writing home about out here on the dead planet, only ruins left behind by an alien civilization long dead. “I heard you loud and clear the first time.” A suprisingly deep but friendly amused voice came through the high definition 3D sound communications system installed into the ship....   [tags: ship, worlds, craft, planet] 1461 words

Demotion of Pluto: Dwarf Planet - From the time Clyde W. Tombaugh first discovered Pluto in 1930, it was viewed as an oddball planet leading up to its reclassification in 2006. For decades, Pluto was once used as a benchmark for the outer reach and size of our solar system. In recent years, new discoveries of celestial bodies within the vicinity of Pluto’s orbit have challenged its planetary status. The debate over Pluto’s classification was discussed throughout several media and news articles, leading to serious controversy amongst astronomers and the decision as to whether or not Pluto should be categorized as one of the planets in our solar system....   [tags: celestial body, Eris and Sedna, dwarf planet ]

However if you look at a scientific encyclopedia the definition is much different and more specific. The Access Science Encyclopedia says a planet is “A) a celestial body that is in orbit around the sun B) has sufficient mass for its self-gravity to overcome rigid body forces so that it can assume a hydrostatic equilibrium shape C) clears the neighborhood around its orbit”....   [tags: solar system, size, sun, IAU, astronomy, orbit]

The Process of Encountering a Planet - There are three phases in the process of encountering a planet with a spacecraft, the launch phase, the cruise phase, and the encounter phase. The launch phase is primarily preparation for the actual launch of the spacecraft, choosing the correct location and time. The cruise phase consists of primarily experiments and slight alterations to the trajectory. The encounter phase consists of any flyby or surface encounter, both are most often designed to conduct experiments and gather data. Prior to launching a spacecraft, extensive knowledge of gravitation, mechanics, interplanetary trajectories, and planetary orbits, is needed....   [tags: gravitation, mechanics, trajectories, attraction]

Pluto: A Planet? - Pluto: A Planet. Many issues have arisen from the debate whether or not Pluto is a planet. Some astronomers say that Pluto should be classified as a “minor planet” due to its size, physical characteristics, and other factors. On the other hand, some astronomers defend Pluto’s planet status, citing several key features. Indeed, most of the problem is that there is no formal definition of a planet. Furthermore, it is very difficult to invent one that would allow the solar system to contain all nine planets....   [tags: essays research papers fc]

For example, biological control reduces alterations of biotic and abiotic processes produced by AIP occurring within the ecosystem (Richardson and van Wilgen 2004).
