His telescope did not contain the magnification necessary to observe Jupiter's lesser moons.
Galileo discovered the four largest moons of Jupiter and that Venus showed phases like those of the moon.
The four moons were discovered sometime between 1609 and 1610 when Galileo made improvements to his telescope, which enabled him to observe celestial bodies more distinctly than had ever been possible before. As a result of improvements Galileo Galilei made to the telescope, with a magnifying capability of 20×, he was able to see celestial bodies more distinctly than was ever possible before. This allowed Galilei to discover sometime between December 1609 and January 1610 what came to be known as the Galilean moons. :)
Currently, we are aware of 63 moons of Jupiter. But each new space probe to Jupiter discovers new moons smaller than the ones before, and it seems likely that there are still a few more yet to be found.Four of Jupiter's moons are big enough that Galileo was able to see them even through his very small telescope; these are Ganymede, Europa, Io and Callisto.
The planet Jupiter was known long before Galileo lived. It is visible in the sky with the naked eye. Galileo discovered that the planet Jupiter has moons. He was able to see four of them and made important observations about their orbits and phases. This was a result of his improvement in the design of the telescope.
Galileo Galei was the first to observe Saturn's rings in 1610 but could not identify them as rings. It was only later in 1655 that Christiaan Huygens was able to prove that they were indeeed rings surrounding the planet.
Jupiter dosent have a surface. And if it did, you wouldn't be able to see the moons because of the 30 mile thick clouds!
Jupiter. The "Galilean" moons are the four largest moons, which are so large that Galileo was able to see them orbiting Jupiter even with his relatively modest telescope.

Galileo published Sidereus Nuncius in March 1610, in which he details his observations of the four large Jovian moons. Therefore the observations he made would have occurred some time earlier in 1610, or perhaps late in 1609. My best guess is that his discovery occurred some time between 8:00 pm and 11:00 pm in the evening.

The first person to discover one of Jupiter's moons was Italian astronomer Galileo. Galileo invented a telescope and was able to modify it to see celestial bodies more clearly than is possible with the naked eye. This discovery occurred between 1609 and 1610.

It was hard life time to accomplish great things but Galileo was able to
Galileo used more advanced technology to find stronger observational evidence than Copernicus was ever able to provide.
You would not be able to see the moons from the surface; Jupiter's atmosphere is too thick.
