Detailed explanation-1: -The Ptolemaic system is a geocentric system such that all are started by assuming that Earth is in a stationary state and it is the center of the whole universe.
Detailed explanation-2: -In the geocentric system, the Earth is considered to be the center of the solar system. The Moon, the planets, the Sun, and the stars all rotate around the Earth (which stays still), with uniform circular motion. They compose the heavens, which are considered to be ethereal and unchanging.
Detailed explanation-3: -In astronomy, the geocentric model (also known as geocentrism, often exemplified specifically by the Ptolemaic system) is a superseded description of the Universe with Earth at the center. Under most geocentric models, the Sun, Moon, stars, and planets all orbit Earth.
Detailed explanation-4: -The geocentric model says that the earth is at the center of the cosmos or universe, and the planets, the sun and the moon, and the stars circles around it.
Detailed explanation-5: -The geocentric model holds that Earth is the center of the Solar system and all the objects in the sky revolve around it. This theory is also called the Ptolemaic theory, which is named after the ancient Greek astronomer Ptolemy.
