What do the outer planets have going around them?
The outer planets in our solar system have many moons orbiting around them. They also have rings, with Saturn being the most well-known for its extensive ring system. Additionally, the outer planets have a variety of spacecraft that have been sent to study them, such as the Galileo spacecraft for Jupiter and the Cassini spacecraft for Saturn.
What are the galilean satellites like?
When Galileo turned his new telescope to Jupiter for the first time, he was puzzled by the fact that there were four other tiny objects clustered around Jupiter. It took several days of observations before Galileo realized that they were moons - going AROUND JUPITER, when Aristotle had said that everything went around the Earth. So, thought Galileo, if some things are going around Jupiter and our Moon is going around the Sun, perhaps Jupiter and the other planets were also going around the Sun. Jupiter has, at last count, 63 moons, but only four are big enough to be seen in a common backyard telescope; Io, Ganymede, Callisto, and Europa. These were named for the lovers of Jupiter. These are the four that Galileo say, so they are called the "Galilean moons of Jupiter".
What did Galileo discover?
He improved the recently invented telescope to see into space, he discovered Jupiter's moons and Saturn's rings. He observed how Jupiter's moons orbited around it and this convinced him that the Copernicus's Heliocentric model (model of planets orbiting around the sun rather than the earth) was correct. Galileo published these ideas and was put on trial for supporting the heliocentric models and going against the Roman Catholic Church's beliefs. He avoided execution but spent the rest of his life under house arrest.
Which ancient astronomer was the first to use a telescope?
Galileo Gailei is the first person credited with using the telescope for astronomical observations. He did not invent the telescope. He is the first to have seen moons going around Jupiter, the rings of Saturn (though he incorrectly identified them), and that the Moon had cliffs and craters.
What else was going on when Galileo became famous?
Because he was the first person in the world to draw sketches of the Moon and the Moons of Jupiter.
How long will it take to go the planet Jupiter?
That would totally depend on how fast you were going. The Galileo spacecraft took six years to get to Jupiter going thousands of miles per hour.

How did Galileo's observations of Jupiter's moons challenge Ptolemy?
Ptolemy claimed everything must go around the Earth, but the moons of Jupiter obviously are not going around the Earth.
What discovery did Galileo make using a telescope?
His primary discovery was the four larger moons of Jupiter, which are called the "Galilean moons" in his honor. It was absolute proof that Aristotle had been wrong about everything in the heavens going around the Earth; here were these four moons going around Jupiter, not the Earth!
Length of years to get to Jupiter using earth years?
That really depends on the speed. A ray of light will take less than an hour to reach Jupiter. Going with a spacecraft with current technology, it takes several years.

What is one well known satellite that visited Jupiter?
The only probe that visited Jupiter and stayed for any length of time was the Galileo probe. Launch from Earth in 1989, it arrived at Jupiter in 1995, and orbited Jupiter and its moon until Sept. 2003, when,due to the deterioration of the orbiter, NASA crashed it into Jupiter's atmosphere. Both Voyagers and Cassini/Huyguens did fly-bys of the planet without going into orbit.
What are the risks of going to Jupiter?
The main risks of going to Jupiter include exposure to high levels of radiation from Jupiter's powerful magnetic field, as well as the intense radiation belts surrounding the planet. Additionally, the extreme atmospheric conditions and pressure on Jupiter could pose significant challenges to any spacecraft or human mission attempting to explore the planet.

Is anyone ever going to Jupiter?
No , no one is going onto Jupiter yet
