All of the basic beliefs were preserved except that Kepler discovered from observations by Tycho Brahe that the planets move in elliptical orbits rather than circles and epicycles. Kepler also made the assumption that the Sun is at the centre of the solar system, which allowed much easier geometrical calculations.
Kepler discovered elliptical orbits by studying the orbit of Mars, which is more eccentric than the other known planets (except Mercury which is difficult to observe).
The eccentricity of Mars's orbit is 9.3% which means that the Sun is displaced from the centre of the orbit by 9.3% of the semimajor axis (the average distance from the Sun). In Ptolemy's theory this had been accounted for by having Mars placed on a relatively large epicycle on the basic circular orbit.
Although this orbit has a relatively high eccentricity, the length of the minor axis of this ellipse differs from the major axis by less than 0.5%, which illustrates the magnitude of Kepler's achievement, and it is the reason why elliptical orbits were not discovered before Kepler's time.
Later, Newton's theoretical discoveries led to an understanding of the mechanisms of elliptical orbits.
What else can I help you with?
How does Kepler and first law of planetary motion overthrow one of the basic beliefs of classical astronomy How about Kepler and second law?
Kepler's First Law of Planetary Motion, which states that planets orbit the sun in elliptical paths rather than perfect circles, challenged the classical astronomy belief that planetary orbits were circular and uniform. This shift underscored the complexities of celestial mechanics and the sun's central role in the solar system. Kepler's Second Law further refuted classical views by demonstrating that a planet moves faster when closer to the sun and slower when farther away, highlighting the variable speed of planetary motion and contradicting the notion of uniform circular motion.
What is the same between astronomy and astrology?
Astronomy is a branch of science that deals with the study of (non-earth) celestial bodies in the universe, such as stars, planets, nebulae, and galaxies.Astrology is based on the belief that celestial bodies influence human lives. It isn't regarded as a science (more as a pseudo-science).Both astronomy and astrology deal with the study of celestial bodies.
What was the first principles of ancient astronomy is that the heavens beyond the atmosphere are perfect and the Earth is corrupt?
Ancient astronomy was based on the belief that celestial bodies moved in perfectly circular orbits, while Earth was considered imperfect due to its changing nature. This idea stemmed from the philosophical notion that the heavens represented the divine and unchanging, while Earth was subject to decay and imperfection.
What was Aristotle's main argument against the heliocentric model?
Aristotle's main argument against the heliocentric model proposed by Aristarchus was that it did not align with his belief in a geocentric universe centered around the Earth. He based his argument on the apparent lack of observable stellar parallax, which he believed would be present if the Earth were in motion around the Sun.
Contribution of Thales?
Thales, a Greek philosopher who is thought to have lived around 625 to 546 BC, was famed for his knowledge of astronomy and may also have brought geometry to Greece. He is known only through references to him in Aristotle's Metaphysics.

Who was Semiramis in the religious belief?
Semiramis were the instigators for starting a false religion. The religion was created to wreck havoc and corruption upon the astronomy that was created by Noah.

What is astronomy and astrology?
Astronomy is the study of everything that lies beyond earth's atmosphere. However astrology is similarly related to stars, they are very different. Astrology is the belief that the stars that the sun passes through from earth's perspective effect those who were born at certain times.
What is the Definition of classical school of management?
Body of the classical school's management thought was based on the belief that employees have only economical and physical needs, and that social needs and need for job-satisfaction either don't exist or are unimportant.
What are the key beliefs and principles of classical dispensationalism?
Classical dispensationalism is a theological framework that emphasizes a strict literal interpretation of the Bible, a distinction between Israel and the Church, and a belief in a future period of tribulation followed by the second coming of Christ. Key principles include the belief in a pre-tribulation rapture of the Church, a focus on the fulfillment of Old Testament prophecies in a future earthly kingdom, and a belief in the importance of Israel in God's plan for the world.
Why did the ancient time period come to an end?
New technologies, civilizations, and belief systems Moved the world from ancient times to the Classical Age
What is the difference between classical mythology and primitive mythology?
primitive mythology is that such as peoples of prehistoric lands. eg belief that a god will heal them classical mythology is more complex, gods animals plants creatures can all be god like or god possesed
How has astronomy affected religion today?
If you look at the meaning of religion which is "A strong belief in a supernatural power or powers that control human destiny" Then look up the meaning of astronomy which is "The branch of physics that studies celestial bodies and the universe as a whole" The the two are unrelated.It is only when you have a belief in Astrology i.e A pseudoscience claiming divination by the positions of the planets and sun and moon, that religion is affected, rather a religion which believes in Astrology as its main source of inspiration. There are many who associate astronomy as a governing factor in their lives.
Classical song in the beginning of American hustle?
Contrary to most people's belief, it is NOT "Hustlin' " by Rick Ross. It's actually "The Flower Duet (Lakmé)" by Léo Delibes.
What kinds of information that is testable now but in the past was pure belief?
Many areas of science are now testable, but were subject to superstition or religious belief in the past. One very simple belief that seems obvious to us now is the fact that the earth circles the sun, easily demonstrated with modern astronomy. Yet in the past, it seemed perfectly obvious that the sun circled the earth. A similar belief would be our recognition that the earth is circular. In the past, belief in a flat earth seemed to be common sense.
