impact? The Pacific Ocean appears to be a large crater - probably the one made by the giant impact. Question 3 Which of the following best explains why we can rule out the idea that planets are usually formed by near-collisions between stars? Stellar near-collisions are far too rare to explain all the planets now known to orbit nearby stars. Question 4 According to our present theory of solar system formation‚ which of the following objects now reside quite far from the place where they formed

death. 1609- Kepler’s first book‚ The Astronomia Nova (New Astronomy)‚ was published. It discussed the orbit of the planet Mars and stated: • Law of Ohm- the sun is located at one Foci(one of 2 centers of an ellipse) • Kepler’s first Law: The orbit of a planet about the Sun is an ellipse with the Sun’s center of mass at one focus. • Kepler’s second Law: A line joining a planet and the Sun sweeps out equal areas in equal intervals of time. • Solved the problem of planetary motion by using Copernicus’s

Those are not the kind of aliens I want to make you believe in though‚ not the aliens from different countries‚ but the one’s from a different world. I strongly believe that the exterestrail life that we havemade movies‚ books‚ and jokes about for years truely does exist and I believe they have visited our planet Earth. - I had watched something on the History Channel once about the Ancient

On my visit to the Adler Planetarium I saw many exhibit galleries‚ ate at the Galileo’s Café‚ and saw the Night Sky Live show. This was my first time at the Planetarium‚ although I have been at all the other museums here in Chicago. I guess I just never had the time for the great Adler. I say great‚ because my experience was way more interesting and pleasing then I expected it to be. The first exhibit that I came upon was “On our Solar System” it had the clone model of the rover that is currently

Fairuz Dalilah Binti Abdul Rashid Are We Alone? : Discovering Life on Other Planets Habitable Zone and The Drake Equation A habitable zone‚ which is also known as the Goldilocks Zone‚ is basically a region where there is a probability in finding the extraterrestrial life. The finding is based on the temperature and the pressure of a certain planetary-mass objects. When the temperature is between 273K and 373K‚ there will be presence of water that can support the extraterrestrial life to live in

because it proved the Heliocentric Theory‚ it has given us information about all of the planets‚ and it has changed our look at astronomy. In the 1600’s‚ the Roman Catholic Church had most of the influence on Europeans. Up to that time‚ most people believed in the Geocentric Theory‚ an Earth-centered theory used by Ptolemy. This theory stated that the Earth is the center of the universe and that all planets travel in circular orbits around it called epicycles (Dolan 15). Because the Church

followers to create a more modern way of life. In the sixteenth century‚ the beliefs of Aristotelian-Ptolemaic were accepted by society. The geocentric theory was one of many that was created during this centaury. This theory is the belief that planets were perfect circles‚ and objects were pulled down due to their compositions. However Copernicus created new theories such as the heliocentric theory which contradicted the older ideas. The heliocentric theory was based off of reasoning and math

Lab #7 Applying Kepler’s Second and Third Laws In this lab we examined the elliptical nature of plametary orbits. In the first part we learned the Law of Equal Areas‚ a law concerning the speed at which planets travel; a line connecting a planet to the sun will sweep out equal areas in equal times; "Kepler’s second law means that a planet’s orbital speed changes with its distance from the sun" The procedure that we follow the orbit of Mar for the year 2004 and 2005. the
