  • Planets In A Solar System
    734 words
    Where the Planets Are In the beginning, the Earth was believed to be both flat and at the center of the universe. Then a sailor set sail to prove that the Earth is in fact round. Decades later science proved that the churches were wrong and in fact the Earth orbited around the Sun not the other way around. Now it is commonly known that the solar system that the human race lives in is just a small part of a much larger spinning body called a galaxy. Now science argues about whether or not Pluto i...
  • Motion Of The Planets

    Johannes Kepler (1571-1630) HIS LIFE Johannes Kepler was a German astronomer and mathematician ho discovered that planetary motion is elliptical. Early in his life, Kepler wanted to prove that the universe obeyed Platonist ic mathematical relationships, such as the planetary orbits were circular and at distances from the sun proportional to the Platonic solids (see paragraph below). However, when his friend the astronomer Tycho Brahe died, he gave Kepler his immense collection of astronomical ob...
  • 700 Km From Neptune's Cloud

    Little was known about Neptune, which was discovered in 1846, until the Voyager 2 encounter in 1989. It has a similar composition to Uranus and is close in mass to Uranus. Its thick atmosphere made of hydrogen, helium, and some methane and ammonia, gives it a bluish color. DISCOVERY On August 25, 1989, the voyager discovered Neptune, but only after traveling 12 years at an average velocity of 19 kilometers a second (about 42 miles an hour). The Voyager 2 observed Neptune almost continuously from...

    BETA PICTORIS: PLANETS? LIFE? OR WHAT? JARA ASTRONOMY 102 SEC 013 The ultimate question is; Is there a possibility that life might exist on a planet in the Beta Pictoris system? First, one must ask, Are there planets in the Beta Pictoris system? However, that question would be impossible to answer if one did not answer the most basic questions first; Where do planets come from? and do the key elements and situations, needed to form planets, exist in the Beta Pictoris system? To understand where ...

    Pluto Come wander with me, she said, Into regions yet untrod; And read what is still unread In the manuscripts of God. - Longfellow Although Pluto was discovered in 1930, limited information on the distant planet delayed a realistic understanding of its characteristics. Today Pluto remains the only planet that has not been visited by a spacecraft, yet an increasing amount of information is unfolding about this peculiar planet. The uniqueness of Pluto's orbit, rotational relationship with its sat...

  • Pluto To A Minor Planet
    1,624 words
    In the outer limits of our solar system there is a planet unlike any other, Pluto. Pluto was discovered in February of 1930 by an American astronomer, Clyde Tombaugh. It is the only planet to have been discovered by an American. All though we have known of the existence of Pluto for over thirty years now, there are still many mysteries surrounding this celestial body. Being the farthest planet has made it difficult to study Pluto, Adding to the obscurity of this strange planet is that the capabi...
  • Pluto A Planet Or Not
    1,589 words
    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 nin...

  • Ptolemy's Model Of Planetary Motion
    743 words
    Claudius Ptolemy was a citizen of the Roman Empire, who lived around the year 100 AD. Ptolemy was influential in the fields of mathematics, astronomy, and geography. In astronomy Ptolemy relied somewhat on the theories and observations of previous astronomers, such as the geocentric model designed by Aristotle; to create his own model of our solar system. Ptolemy's model of planetary motion was one of his greatest contributions to the science of astronomy. The model (seen in 1.1) was based on a ...
  • Clyde Tombaugh The Discoverer Of Pluto
    1,999 words
    "To the Stars Through Difficulties" is the state motto of Kansas, the place where Clyde Tombaugh the discoverer of Pluto grew up. But it is impossible to talk about Tombaugh without speaking of Percival Lowell who first noticed that there was an anonymous ninth planet beyond Neptune, and he called it Planet X. These two ingenious and analytical men who never worked physically together were honorable and true to the work and effort put forth to find Pluto (Planet X). The motto of Kansas is an app...
