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 - ... The planetesimals form from solid materials around the star and the embryos they create come together to form giant solid planet cores that are about 5-20 Earth masses. Such massive cores are gravitationally strong enough to trap and maintain any nebular gas and grow in to massive gas giants before their stars temperature rises and disburses any remaining gas in its nebula (Gladman 1998). Armitage and Hansen took the Embryo model further and they hypothesized that young forming gas giants heavily interact with the nebular disk of dust and gas (Armitage and Hansen 1999)....   [tags: Astronomy]

The scientific community, including Galileo, firstly refused his hypothesis that the moon caused the tides on Earth and demanded it was unscientific ("Previous Posts - Mormonsandscience" 13). Then again, Kepler’s three laws of planetary motion did much of a better job of upholding precision than the earlier views in relation to circular orbits, and so the scientific community immediately supported them ("Johannes Kepler" 2). Conversely, in modern times, Kepler’s theory is seen as correct by the scientific community, exceedingly effective and valid to society, being able to be applied to more than just what Kepler was aware of....   [tags: Astronomers]

Investigation of Dark Matter - Investigation of Dark Matter Introduction Throughout the years, scientists have been looking for the missing mass of the universe; it has yet remained an unsolved mystery. Using different methods, scientists have tried to determine the mass of the universe and surprisingly found a discrepancy suggesting that ninety percent of the mass of the universe is nowhere to be found. Then here comes the term “dark matter”, referring to this unfound matter of the universe. It is called dark because it gives off no light and matter because it has to have some mass to be able to explain the effects that they produce....   [tags: Papers] 2409 words

Is There Anyone Out There? - ... When considering super earths, one must remember that mass is not the only geographic asset of a life-sustaining planet, as a planet made of gas could not support life; solid formations would not have solid ground to stabilize upon (Spotts). A “Goldilocks zone” is the habitable zone surrounding a star, described as the area around a star that is not too hot and not too cold to sustain life. More specifically, water on a planet in this zone would not be consistently boiling or freezing (Kaufman)....   [tags: Astronomy]

Maintaining an atmosphere is essential for life to exist and small a planet with a small gravitational force at its surface may not be capable of retaining one. The Kepler transit data can only measure planet masses, diameters, orbital periods, and parent star types and although this information is useful for determining habitable zones, further data is required to determine true habitability....   [tags: Astronomy]

As stated above, as the gas cloud shrank the thermal energy increased, due to the conservation of energy. This increased the temperature of the gas's within.

Comets are small, fragile, and irregularly shaped. Most are composed of frozen gas. However, some are composed of frozen gas and non-volatile grains. They usually follow very strict paths around the sun. Comets become most visible when they cross the sun. This also applies to people who view comets with telescopes.
