Galileo challenged church teachings by saying that the heliocentric model of the universe was trueThe Catholic Church charged him with heresy. Due to his support of the heliocentric or sun centered theory. Which directly opposed the Church accepted theory that the sun and planets revolved around the earth.
A heliocentric model is a model of the planets' movements that places the Sun at the centre of the Solar System. Copernicus's model published in 1543 was the first heliocentric model. It resembled the Ptolemaic model in respect of the circles and epicycles that were used to explain the planets' movements. Kepler's model published in 1609 was also heliocentric, but it used planar elliptical orbits for the planets, which follow Kepler's 3 laws of planetary motion. It is now the accepted model.
What he withdrew was his insistence that the heliocentric theory represented the absolute truth. He did that when challenged by the Vatican to come up with a demonstration that it was true, which he could not do. However after Galileo's lifetime further discoveries were made that showed that the heliocentric theory was better than the other possible theories and it is now generally accepted.
The Vatican did not believe in heliocentric theory for a long time.
Galileo did not propose a heliocentric theory, he agreed with Copernicus and his heliocentric theory. The Catholic church, at the time, disagreed and they held a huge amount of power and put him on trial.
The planets Uranus and Neptune were discovered only in modern times after the heliocentric model had been generally accepted.

The first person to theorize a heliocentric solar system was Aristarchus, a greek philosopher. However, he was ridiculed, and the first person to have the idea accepted was Copernicus.
Heliocentric: It is the model that states that the sun is in the center of our solar system.
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.
Even more so. It's not even a theory anymore, it's a proven fact.
The heliocentric theory became widely accepted when it was found that the Sun is by a long way the most massive object in the solar system. That happened in the 18th century.

The sun is the center in the Heliocentric
Its main strength is that it is the model which is universally accepted by everyone. Copernicus put forward a heliocentric model that used circular orbits. That meant he couldn't completely eliminate all the complications of the old geocentric model, such as "epicycles". Later Kepler showed that the planets move in elliptical orbits. The basic idea of the heliocentric model is that the Sun is at the centre. One of the main strengths is the simplicity of the heliocentric model. Kepler's version (still used today) of the model with its elliptical orbits is particularly elegant and simple, with no epicycles.
copernicus coined the heliocentric theory...
