Who thought that the earth was the centre of the universe and that the planets had circular orbits?

The geocentric model, where Earth is the center of the universe and planets have circular orbits, was proposed by ancient Greek astronomer Ptolemy in the 2nd century. This model was accepted for over a thousand years until Copernicus introduced the heliocentric model in the 16th century.


Who discovered that planets orbit the sun?

The idea that planets orbited the Sun had been thought of many times before, but it was not until the 17th century that this idea was actually supported by evidence from the first telescopic observations of Galileo Galilei.


Does all the planets revolve around the earth?

No, all the planets in our solar system revolve around the sun. The idea that all celestial bodies revolve around the Earth is known as the geocentric model, which has been replaced by the heliocentric model proposed by Copernicus in the 16th century.


How did Kepler the planet get its name?

There is no planet named Kepler. There are, however, many planets with designations such as Kepler-22b. These planets are named as such because they were discovered using the Kepler spacecraft. The spacecraft is named after Johannes Kepler, a 16th-17th century astronomer who defined the laws of planetary motion.


How many times does the sun go around?

The sun does not go around anything. It stays relatively stationary in the center of our solar system while the planets orbit around it. This is known as heliocentrism, which was proposed by Nicolaus Copernicus in the 16th century.
