He Discovered that Earth was not the center of the solar system , Jupiter Has four moons and Venus has light and dark phases, like a moon! He also discovered the rings of Saturn. All this using just one telescope?
Galileo didn't invent the telescope, but he was the first person we know of to point a telescope into the skies - and discovered that Jupiter wasn't just a bright light in the sky, but was an enormous planet with moons of its own. The four largest are called the "Galilean" moons; Ganymede, Europa, Callisto and Io.
he found out theres 18 moons
He Discovered that Earth was not the center of the solar system, four of Jupiter's
moons, and that Venus has light and dark phases, like a moon. He also discovered the rings of Saturn.
the moon had mountains and that the sun spins
1. The lunar craters
2. Four satellites of Jupiter
Galileo used a reflecting telescope. A reflecting telescope uses two mirrors, one facing the sky, and one reflecting the light from the first mirror

Galileo discovered the four largest moons of Jupiter and that Venus showed phases like those of the moon.
Galileo Galilei didn't actually invent the telescope. A Dutchman, Hans Leppershey, invented 'a device used to hold two lenses apart that focused on refracting light through the lenses to make objects look closer' in 1608. He applied for a patent on it but it was declined because other scientists claimed to have made similar items. Galileo heard of this and decided to build his own, calling it a 'looking glass' that was based on Leppershey's work.
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.
We don't know exactly who invented the telescope, but some time around the beginning of the 17th century, Dutch spectacle (eyeglass) makers noticed that two lenses could be used to make distant objects appear closer and bigger. After Galileo heard about this, he made a telescope (although not the first) and started to make important discoveries. There have been thousands of discoveries since then, many showing us our place in the universe and providing information about the origin and evolution of the universe.

Back then Galileo looking at Saturn far away had a small telescope he saw saturns rings thinking it was two humps

First the dutch made a telescope with only two lenses in it. After Galileo heard about this, he decided he wanted to try and make one more better and advanced. And his mission was a sucess! After that, there was orders pouring in like crazy for the telescope.
Galileo discovered two important things: the moons of Jupiter and the phases of venus. Both discoveries raised doubts about the old Ptolemaic system which was geocentric, and the phases of Venus showed that it was definitely wrong. But neither discovery proved that Copernicus's theory - supported by Galileo - was right. This is because Tycho's geocentric system explained the phases of Venus satisfactorily.

He built his first telescope and started to make observations. He discovered the phases of Venus and sunspots. He built his first telescope in 1609. Galileo's taught mathematics and actually made a few discoveries in physics. When he heard about the inventor of the telescope and he wanted to improve it.

Many historians explain that Galileo was the first person to use a telescope. In 1610 Galileo discovered Saturn's rings. He also observed Jupiter's four moons and viewed the different phases of Venus. This lead to the study of sunspots and various celestial activities. Even though Galileo is credited with being the first to make practical improvements and enhancements to the use of the telescope, he was not the inventor, and therefore not the first person to use a telescope. That person would be Hans Lippershey. Hans Lippershey was born 1570 in Germany, but was raised in Holland. He invented the first refracting telescope in 1608. A lens maker, he designed this telescope from two lenses and applied for a patent, intending that it would be important for the military. He successfully demonstrated the usefulness of his refracting telescope to the military.
