The Earth was the center of the universe and the "heavenly bodies", such as the moon, sun, planets and stars, rotated in their own spheres around the Earth in a pattern. The order of spheres from Earth outward are:
A model which showed that Earth was the center of the Universe
The Ptolemaic model of the universe was that the Earth was the center of the solar system and all the other planets revolved around it, including the Sun. The nine concentric spheres of his model followed this order (from innermost to outermost sphere): Earth (unmoving in the center), Mercury, Venus, the Moon, the Sun, Mars, Jupiter, Saturn, the fixed Stars, and the Primum mobile. The Ptolemaic model of the universe also included epicycles. Epicycles were small circles or sphere on which each planet moved. These epicycles moved on a larger sphere called a deferent. It was assumed that the stars moved on a celestial sphere around the outside of the planetary spheres.
The Ptolemaic system of the universe is the most influential of the geocentric cosmological theories. It places the earth motionless at the center of the universe with all celestial bodies revolving around it.
(It was named for the Greco-Egyptian astronomer Ptolemy. The system dominated Astrology until the heliocentric system in the 16th century, created by the Polish astrologer Copernicus.)

Copernicus
Brahe's theories revolved around the ptolemaic system, where Earth was the centre of the Universe. Copernicus stated that the Earth is not the center of the Universe, but we revolve around other masses as well.
The name is of the general theory where celestial objects revolve around the Earth is known as the Ptolemaic system.
"Two things are infinite: the universe and human stupidity; and I'm not sure about the the universe."
the Declaration of Independence
This model of the universe placed the Earth at the center of the universe
A Ptolemaic view of the Universe has the Earth at it's centre. The Copernican centres on the sun. Both however have been found to be incorrect.
at the center of the universe
Copernicus
Earth
In the Ptolemaic Greek model of the universe, the stars are thought to be attached to the celestial sphere, a hypothetical invisible sphere surrounding the Earth to which the stars were fixed. This model placed Earth at the center of the universe with all celestial bodies orbiting around it.
celestial sphere . . . ?
In Copernican scheme, the sun is the center of the solar system, while in the Ptolemaic system, the earth is the center of the universe and all the bodies of the universe revolve around it :) -iloveu armstrong11-12 Munsci :)

The geocentric universe, so named because it was believed that everything revolved around the Earth. The view was eventually displaced by the heliocentric solar system, where the Earth and other planets revolve around the sun.
