The Universe does not have a centre.
What did Aristotle and ptolemy believe about the universe?
The Ptolemaic system dates back to about 140 AD and has the Earth at the centre of the universe and everything else around it. This view was incorporated into the scriptures. It explains the planets' movements among the stars quite accurately and was used into modern times in the mechanisms of planetariums until computerised mechanisms came along. It was not until 1543 that Copernicus published an alternative view, in which the Sun is at the centre and the planets' orbits are geometrically simpler. Kepler produced another Sun-centred model in 1609 with the planets in elliptical orbits. This latest theory was eventually accepted by astronomers after it was married up with the new theory of gravity and the laws of motion.
Nicolaus Copernicus showed that the universe is what?
The sun was the centre of the Universe
Who thought that the earth was the centre of the universe and that the planets had circular orbits?
Ptolemy, but he was wrong the sun is in the center and planets have elliptical orbits.

What did the Copernicus universe suggest?
Copernicus suggested a heliocentric model of the universe. Meaning, the earth was the centre of the universe and other planets had to orbit around the earth. This model of the universe was against Ptolemy's model of a geocentric model; a stationary Earth at the centre of the universe.
Why did people think that Copernicus was wrong?
Everyone thought that the sun orbits the Earth and all other planets but Copernicus studied the ski carefully. He found out that the Earth and all other Planets orbits the sun and the earth is not the centre of the universe. The sun is.
What is heliocentrism?
In Heliocentrism, the Sun (Helios) is said to be at the centre of the universe.
What is the difference between geocentric heliocentric and planetary motion?
Geocentric motion of planet is that in which earth is at the centre of the universe and all other planets revolving around it.Heliocentric motion of planets is that in which sun is the of universe and other planets revolving around it.In planetary motion all the planets includes Earth revolving around the Sun in their fixed orbit.
How are the planet's moving in the universe?
Mainly the planets orbit round the Sun and can be considered as a closed system with the Sun fixed at the centre. However the Sun revolves around the centre of our local galaxy as well.
