Module 2 Flashcards
Proposed the heliocentric model of the universe, challenging the prevailing geocentric view and revolutionizing our understanding of planetary motion.
Nicolas Copernicus
His work laid the foundation for modern astronomy and set the stage for subsequent advancements in the field.
Nicolas Copernicus
A theory that believes the Sun is the center of the solar system, with the planets, including Earth, orbiting around it.
Heliocentric Theory
It revolutionized our understanding of celestial motion, challenging the long-held geocentric view and paving the way for advancements in astronomy and our perception of the universe.
Heliocentric Theory
A prominent astronomer, who observed and record the positions of celestial bodies.
Tycho Brahe
His precise and extensive data became a valuable resource for Johannes Kepler, who used it to develop his laws of planetary motion and provide further evidence for the heliocentric model.
Tycho Brahe
It was a supernova explosion that Tycho Brahe observed and documented, leading to a profound shift in the understanding of the universe.
1572 Supernova
provided valuable data that contributed to the advancement of astronomy and our knowledge of the celestial sphere during Tycho Brahe’s time. An extensive observations of stars his cataloging of “___” stars,
777 Stars
The effect whereby the position or direction of an object appears to differ when viewed from different positions
Parallax
Brahe’s observations and measurements of planetary positions led him to conclude that the planets, including the Sun, revolved around the Earth. This aligned with the geocentric model, which was the dominant cosmological view of the time.
Geo-Heliocentrism
Brahe believed that the Earth was fixed at the center of the universe, while the Sun and Moon orbited around it. On the other hand, he proposed that the other planets orbited around the Sun, which itself orbited around the Earth.
Geo-Heliocentrism
Formulated three fundamental laws of planetary motion that revolutionized our understanding of the solar system.
Johannes Kepler
Described the elliptical orbits of planets, the equal areas law, and the harmonic relationship between a planet’s orbital period and its distance from the Sun, laying the foundation for modern celestial mechanics.
Johannes Kepler
Kepler’s Law of Planetary Motion
• The Law of Ellipses
• The Law of Equal Areas
• The Law of Harmonies
He was credited with significantly improving the design of the telescope and using it to make groundbreaking astronomical observations. Although he did not invent the telescope, he made important modifications that allowed him to study celestial objects in unprecedented detail.
