The main heliocentric models are the ones by Copernicus and Kepler.
Heliocentric is used to describe a model of the solar system that has the Sun at the centre. Models with the Earth at the centre are descrined as geocentric. There are four major models of the solar system: Geocentric: Ptolemy, Tycho Brahe; Heliocentric: Copernicus, Kepler. These four can all predict the movements of the planets among the stars with reasonable accuray. The one that is accepted as correct today is Kepler's, because it is the only one that is consistent with later theoretical discoveries in gravity and the laws of motion.
Geocentric models had the earth as the center of the universe with the sun and all the planets orbiting it. Heliocentric models (the current accepted ones) have the sun as the center, with the earth and planets orbiting it.
"Heliocentric" is Latin for "Sun centered".

Newton's greatest achievements are the Law of Gravity, his laws of Motion, his development of Calculus, the Reflecting Telescope, his Theory of Light and his use of data, experiments and mathematical models.
heliocentric model. Probably the "geocentric model" is what's meant, because the heliocentric model is "modern".
The Moon.
The heliocentric model places the sun at the center of the solar system where the gercentric model places the Earth at the center.
The planets Uranus and Neptune were discovered only in modern times after the heliocentric model had been generally accepted.
New scientific models are developed in order to reflect the most recent discoveries.
