TAILIEUCHUNG - Rourke’s World of Science Volume 7 Astronomy and Space

In 140 . a Greek astronomer named Ptolemy wrote that the Earth was the center of the universe. He thought all the stars, the Sun, and the Moon revolved around it. This made sense because that is how things looked in the sky from Earth. We call Ptolemy’s theory the geocentric view. It is derived from geo (Earth) and centric (center). Astronomers believed the geocentric view for 1,500 years until 1543. The Heliocentric View About 500 years ago, Copernicus found that the Earth and other planets revolve around the Sun. His theory was published in1543. We call Copernicus’s theory the heliocentric view because helios means sun. Astronomers still base their understanding of the Solar System on Copernicus’s heliocentric view | Rourke s World of Science Volume 7 Astronomy and Space By Tim Clifford Editorial Consultant Luana Mitten Project Editor Kurt Strum Rourke Publishing LLC Vero Beach Florida 32964 Table of Contents What is Astronomy .4 Key Events in the Early History of Views of the Universe .8 How People Used the The Solar System .12 The Origins of Our Solar The Sun .16 Earth s Mars .25 Neptune .36 Pluto and the Dwarf Planets .38 Asteroids Meteoroids and Stars .42 What is a Star .42 Types of Stars .44 The Life Cycle of a Types of Galaxies .48 The Milky Other The Universe .52 Origins of the Universe .53 Possible Ends of the Universe .55 Space Exploration .57 Space Humans in Space .60 A History of Manned Spaceflight .61 A History of the United States Space Shuttle People Who Study 4 Astronomy and Space What Is Astronomy Have you ever looked up in the universe or outer space and can sky and wondered what life would help you find the answer to your be like if you lived on Mars question.
