Chapter 14 Section 2 Notes: The Sun The sun produces energy through nuclear fusion. In the process of nuclear fusion‚ two atomic nuclei combine‚ forming a larger‚ more massive nucleus and releasing energy. Within the sun‚ hydrogen atoms join together to form helium. Such conditions exist in the sun’s core‚ or central region. The sun’s interior consists of the core‚ the radiation zone‚ and the convection zone. The sun’s energy is produced in its central core. The radiation zone is a region

Saturn is the second largest planet in the solar system. Because Saturn is bigger than Earth‚ you would weigh more on Saturn. If you weigh 100 pounds on Earth you would weigh 112 on Saturn. The Romans gave the planet Saturn its name after their god of agriculture. Saturn is 74‚899 miles wide (120‚535 kilometers wide). It takes Saturn ten hours and forty minutes to complete one single rotation‚ isn ’t that cool! One day on Saturn is only ten hours long‚ ours is twenty-four hours long. Thirty years

is Earth the only planet in our solar system capable of sustaining life? Why is Earth the only planet in the solar system that has plentiful liquid water and an atmosphere that can protect the planet from the harmful ultra-violet rays of the Sun? What makes Earth so special? These are some of the questions that will be explored in greater detail as we use Comparative Planetology to understand what makes Earth a habitat for life and what makes it so different from the other planets in our solar system

Physical Science Planet Project 5/3/11 [pic] After the discovery of Uranus‚ scientist noticed the orbit was not as it should be in accordance to Newton’s law. Neptune was discovered by Johann Galle on September 23‚ 1846. Neptune has been visited by the Voyager 2; it flew by the planet on August 25‚ 1989. It was the first planet to be found by a mathematical prediction. Alexis Bouvard thought the change in Uranus’s orbit changed by gravitational perturbation by an unknown planet. The

The term derives from the children’s story of “Goldilocks and the three bears” where the girl wanted everything just right‚ for example “not too hot or cold‚ not too hard or soft….” Our Earth has the perfect conditions for life‚ the perfect distance from the sun that is not too hot or cold‚ allowing a large amount of water to be present in liquid form. These conditions are

The Title of Planet Must be Given Back Voting done at the International Astronomical Union convention about pluto’s status of being a planet was a harsh new reality‚ with the majority voting for pluto’s demotion. Professor Alan Stern‚ chief scientist for the New Horizon mission set for learning more about pluto‚ called the outcome "an awful decision" and described the new definition as "internally inconsistent" ("Why Is Pluto No Longer a Planet?"). The debate of pluto being a planet has started

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
