18.1: Introduction to the Solar System

Galileo''s discoveries caused many more people to accept the heliocentric model of the universe, although Galileo himself was found guilty of heresy for his ideas. Watch this animation of the Ptolemaic and Copernican models of the solar system. Ptolemy made the best model he could with the assumption that Earth was the center of the

Galileo sparked the birth of modern astronomy with his observations of the Moon, phases of Venus, moons around Jupiter, sunspots, and the news that seemingly countless individual stars make up the Milky Way

What did Galileo Galilei discover?

Galileo Galilei (1564-1642) – Italian astronomer, scientist and philosopher, who played a leading role in the Scientific Revolution. Galileo improved the telescope and made many significant discoveries in astronomy. His findings encouraged him to speak out for the Copernican view that the earth revolved around the sun.

Heliocentric Theory

These ellipses show that Earth does indeed have the expected orbital velocity around the solar system '' s center of mass. Final proof of the heliocentric theory for the solar system came in 1838, when F.W. Bessel (1784-1846) determined the first firm trigonometric parallax for the two stars of 61 Cygni (Gliese 820).

Galileo''s observations of Venus were exactly what was predicted by the _____ model of the Solar System. heliocentric. Galileo''s observations of the phases of Venus proved that the _____ model of Ptolemy is incorrect. geocentric. Galileo''s observations of _____ showed that it orbits the Sun and not the Earth.

Galileo Galilei: Biography, Inventions, Contribution

Galileo''s observations extended to the sun and Venus as well. Galileo noted the presence of sunspots, which contradicted the idea that the sun was an unblemished and unchanging entity. Galileo observed the phases of Venus, a phenomenon that further supported the heliocentric model of the solar system.

Our Solar System – revolutionary ideas

Ptolemaic model. In the second century CE, Ptolemy, who lived in the Egyptian town of Alexandria, produced a mathematical representation based on observation of the known Solar System. In Ptolemy''s model, the Earth was at the centre of the Universe, with the Sun and planets revolving in a series of circular orbits moving out from the Earth.

Understanding the Cosmos: Changing Models of the Solar System

However, when Galileo saw the moon through a telescope and discovered that it was actually cratered and mountainous, he argued against Aristotle''s interpretation. Galileo included drawings of the moon in his treatise Sedarius Nuncius as evidence to support his argument about the nature of the cosmos.

Galileo''s observations of the different phases of the planet Venus provided further support for the heliocentric model of the solar system developed by Nicolaus Copernicus. In his model, all phases would be visible because the orbit of Venus around the Sun would cause its illuminated hemisphere to face the Earth when it was on the opposite

model of the solar system. Explain how Galileo proved that his model

The Galileo model is explained as: The Galileo model of the solar system involved the sun at the center of the solar system. He used his telescope to prove that all planets revolve around the Sun, in a solar system. Galileo proved the Ptolemy model wrong by proving that Venus went through full sets of phases similar to the moon.

The geocentric model of the solar system outlined above represents a perfected version of Ptolemy''s model, constructed with a knowledge of the true motions of the planets around the sun. Not surprisingly, the model actually described in the Almagest deviates somewhat from this ideal form. In the following, we shall refer to these deviations as
