Copernicus is famous for advancing the view that the Sun is the center of the solar system, and that the Earth and other planets orbit the Sun. This heliocentric (sun-centered) system is contrasted with the geocentric (earth-centered) system in which the Earth is the center of the solar system, and the Sun and planets move around the Earth.

Johannes Kepler and Tycho Brahe worked together beginning in 1600. Kepler used Brahe's extensive and accurate observations to create his own model of the universe. Kepler's model was also based on mathematics, and one of his first discoveries was that the orbit of Mars is an ellipse with the sun at one focus, and the speed of the planet in its orbit varying in a calculable way. This information was discovered in 1609 and is the basis of the first and second of Kepler's Three Empirical Laws. The first law states that the orbit of each planet is an ellipse with the Sun at one focus. The second law states that the radius vector to a planet sweeps out equal areas in equal intervals of time. Kepler formulated his third law in 1619; it states that the squares of the sidereal periods of the planets are proportional to the cubes of the semimajor

Copernicus correctly sated that the earth was not the center of the universe while Ptolemy stated that the earth was the center of the universe . potlemys theory was incorrect on all occasion. while Copernicus corrected them

Copernicus thought that the Earth was not in the center of the universe but no one believed him until Galileo Galilei proved him correct.

By observing sunspots Galileo concluded that the sun was what?

was rotating on the circumfrence on deznuts


What observation led to Galileo to the conclusion that the sun rotate?

The observation that led Galileo to conclude that the sun rotated was when he looked through his telescope and noticed that their were sunspots on the sun. He later looked through the telescope once again and couldn't see the sunspots.


What are two methods for determining how fast the sun rotates on its axis?

Observing sunspots, and checking sunlight for the Doppler effect. There are probably a few others, too.Observing sunspots, and checking sunlight for the Doppler effect.

What are the two observation that Galileo made?

Galileo looked at the sun and observed dark blemishes on its surface (which are now called sunspots). From the movement of these blemishes, he was able to determine that the sun has a rotation period of about one month.


What can you conclude from your observation from sunspots?

Yes. This is called sunspot extrapolation. For the past 400 years, scientists have been observing the sunspot populations. They have found a variety of qualitative (non-numerical) and quantitative (numerical) data and have concluded that the number of sunspots peaks and falls at a cycle of approximately 11 years.

Who studded the movement and the sun spots?

The study of sunspots began back in 1609 by Galileo. Galileo noticed the sunspots while gazing through a telescope. The actual study did not commence until 1612.

What is the dark area on the sunspot?

It was Galileo who first studied the dark spots found in the Sun which are now referred to as sunspots. It is believed that the intense magnetic fields surrounding the sun cause the appearance of sunspots.


What did Galileo use a telescope for?

He used it to study the moon, Jupiter's moons, Saturn, Venus and the sunspots on the sun.


How did Galileo find Saturn?

..he found it by looking through a telescope and observing it around the sun.
