Things, moons or other objects, stay in orbit aournd whatever they orbit becasue they are moving at just the right speed. As the object falls X distance down from an orbital height of Z, it also moves Y distance horizontally. That Y distance is just enough so that at the end it is at Z distance above the surface because the surface below is round and movement puts it over a part that is curved "down."
This is an awkward description of free fall. The object is always falling down but its sideways motion keeps it at the same height above the planet.
The moons stay in orbit around Jupiter due to the planet's gravitational pull. Gravity is the force that attracts objects with mass towards each other, keeping the moons in orbit around Jupiter as they continuously fall towards the planet but also travel sideways at a fast enough speed to avoid crashing into it.
The moons stay in orbit around Jupiter by the force of gravity.
The moons stay in orbit around Jupiter due to the planet's strong gravitational pull. This gravitational force keeps the moons in check and prevents them from moving away into space. They orbit around Jupiter because of the balance between their inertia and the gravitational force pulling them towards the planet.
Jupiter has an enormous amount of mass. Amounts of matter that large create enough gravitational pull to hold another body in its orbit (The Sun has countless objects orbiting it, but only relatively few of these objects are remarkably large). The moons don't fall into Jupiter because the forces in question are in constant "struggle." The moons are constantly trying to move in a straight line, but the gravity pulls them in at a relatively uniform rate. These two forces keep the moons moving in a certain circular path around the planet. Since Jupiter's gravity and the amount of space around it allow for it, it has dozens of natural satellites, 3 of which are larger than our moon, one of which is slightly smaller, and the rest of which are far smaller than our Moon.
"Jupiters moons orbit Jupiter because gravity pulls them"Is only half correct. Gravity from Jupiter does, indeed "pull" them toward Jupiter. But, there is an equal and opposite Force, we'll call it Energy, that is "pushing" and keeping those moons (as well as our moon, our earth and our atom's electrons) from flying out of orbit. Those Two Forces, in Balance, can be felt by holding two bar magnets toward each other, then reversing them: one "pull', one "push" Force!Magnetism is the Cosmic Glue that holds the Universe together!Physics is pretty simple, huh..?Another Answer:Unfortunately, 'Magnetism is NOT the Cosmic Glue that holds the Universe together'. Gravity is the force that 'helps' to hold the Universe together, but is not really doing its JOB. The Galaxies of the Universe are flying apart from each other at an Accelerating Rate. Possibly due to "Dark Energy".As for the Moons, well, the force of Gravity and the Centrifugal (and Centripetal) Forces are in balance, so the moons will stay in Orbit. Think of a Ball on a string being swung around your head in a circle. Then think of Gravity (and Centripetal force) as the String holding the Ball in its circular path.
The moons stay in orbit around Jupiter due to the gravitational pull of the planet. As of June 2014, Jupiter has 63 known moons.
yes and no there;s no answer
Gravity holds satellites in orbit.
Gravity, just like our moon. gravity pulls it around

The moons stay in orbit around Jupiter due to the planet's strong gravitational pull. This gravitational force keeps the moons in check and prevents them from moving away into space. They orbit around Jupiter because of the balance between their inertia and the gravitational force pulling them towards the planet.
The Galilean moons—Europa, Ganymede, and Callisto—remain in orbit around Jupiter due to the planet's strong gravitational pull. This gravitational force keeps the moons in stable orbits as they revolve around Jupiter. The balance between their orbital velocity and Jupiter's gravitational pull keeps them from escaping or falling into the planet.
bob is jupiter and he grabs the back when they go away

Io, Ganymede, Callisto, and Europa stay in orbit with Jupiter cause Jupiter has a strong gravitational pull on celestial bodies around it.
cause they stay i orbit because of jupiters gravity not there own so jupiter would suck the gas from its moons but not vice versa
