He did not need to discover that as it was already known by the ancient Greeks.
Galileo Galilee proved that the earth is round by earths shadow on the moon.
Galileo discovered the moons of Jupiter, which were the first objects discovered that orbited round something other than the Earth. Before then, it was assumed that everything in the universe rotated around the Earth. Galileo discovered objects revolving round Jupiter, but that on its own did not show that the geocentric Ptolemaic model was wrong.
He discovered that they orbit around Jupiter, the first example of anything that did not orbit round the Earth, which lent support to the idea that the Sun might be at the centre of the solar system. After Galileo's lifetime, with further scientific discoveries, this was discovered to be true
Galileo discovered the four largest moons of Jupiter (later named the Galilean moons), mountains and craters on the moon, phases of Venus, and sunspots on the sun. These observations supported the heliocentric model of the solar system and challenged the geocentric view of the universe.
They are the four large moons, discovered by Galileo, that go round Jupiter.

The ancient Greek philosopher Pythagoras is often credited with being one of the first to propose that the Earth was round in the 6th century BC. However, the idea of a spherical Earth was further popularized by the philosopher Plato and astronomer Aristotle.
