Why, the telescope, of course! Using his telescope, Galileo was able to make observations of the heavens in a way no one else was able to before.
The idea that planets orbited the Sun had been thought of many times before, but it was not until the 17th century that this idea was actually supported by evidence from the first telescopic observations of Galileo Galilei.
Galileo Galilei was supposedly the first, but some say that Englishman Thomas Harriot drew maps of Earth's moon a few months before Galileo discovered it.
Galileo and also my hamsters! my best friend is Katie Jennings!
Jupiter's moons orbited it and thus did not have a the earth as their axis of rotation.

Galileo Galilei
Galileo's observations with his telescope supported the concept of heliocentricism. He noted that the satellites of Jupiter and Venus, based on their range of phases, did not match geocentricism supported by Ptolemy. He noted that based on these findings, that the Heliocentric theory was correct.
Galileo was supported by his teacher, Ostilio Ricci.
Galileo Galilei . He only helped support the theory through his observations , he didn't invent the model, Copernicus did.
Copernicus (16C); supported later by Galileo using observations aided by the newly-developed telescope.
the Earth revolves around the Sun, which challenged the geocentric model of the universe. His discoveries also supported the heliocentric model proposed by Copernicus. Galileo's observations with the telescope provided evidence for this idea.
This was because his observations contradict the biblical view of the church, who were immensely powerful at the time. Galileo's observations placed the sun as the center of our galaxy instead of the earth.
Pythagoras Galileo was the person who made the first famous observations with a telescope.
I suspect the answer you're looking for is Galileo Galilei. It just has two problems: Galileo didn't "invent the telescope", nor did he "develop a heliocentric view of the universe." The telescope was invented in the Netherlands; Galileo simply improved on it and was probably the first to apply it to astronomical observations instead of just looking for distant ships. Also, Copernicus is (properly) credited with the heliocentric view; Galileo's observations supported this, but he didn't come up with it.
Copernicus developed the theory, Galileo supported it with his observations.
