The Copernican Model: A Sun-Centered Solar System The Earth-centered Universe of Aristotle and Ptolemy held sway on Western thinking for almost 2000 years. Then, in the 16th century a new idea was proposed by the Polish astronomer Nicolai Copernicus The Heliocentric System In a book called On the Revolutions of the Heavenly Bodies (that was published as Copernicus lay on his deathbed), Copernicus proposed that the Sun, not the Earth, was the center of the Solar System. Such a model is called a heliocentric system . The ordering of the planets known to Copernicus in this new system is illustrated in the following figure, which we recognize as the modern ordering of those planets. The Copernican Universe In this new ordering the Earth is just another planet (the third outward from the Sun), and the Moon is in orbit around the Earth, not the Sun. The stars are distant objects that do not revolve around the Sun. Instead, the Earth is assumed to rotate once in 24 hours, causing the stars to appear to revolve around the Earth in the opposite direction. Retrograde Motion and Varying Brightness of the Planets The Copernican system by banishing the idea that the Earth was the center of the Solar System, immediately led to a simple explanation of both the varying brightness of the planets and retrograde

C CALDERA A caldera is a large depression at the top of a volcano, caused by collapse or explosion. CALLIPUS Callipus of Cyzicus (370 - 300 BC) was an ancient Greek who accurately measured the length of the seasons. Callipus improved the Greek calendar, reconciling the lunar month with the solar year, by introducing a unit of time called the Callippic cycle (it was an improvement on the Metonic cycle of 6939.6 days or 19 solar years or 235 lunar months; the Callippic cycle was 4 Metonic cycles). He also added to the (incorrect) theory of the motions of the plants, as spheres within spheres, adding 7 more spheres to Eudoxus' system. CALLISTO Callisto is a large, icy, dark-colored, low-density outer moon of Jupiter that is scarred with impact craters and ejecta. It has a diameter of about 3,000 miles (4800 km), the second largest moon of Jupiter, roughly the size of Mercury. It orbits Jupiter at a mean distance of 1,170,000 miles (1,883,000 km). Its mass is 1.08x10
