Does a satellite Need fuel?
Satellites tend to use nuclear reactors or solar energy, instead of fuel, to power themselves. Out in space, the sun is an excellent and plentiful source of energy. This is why spacecraft like the International Space Station and the Hubble Space Telescope run on solar power.

Which planet has the most natural satellites?
Jupiter
Saturn and Jupiter have the most moons, with dozens orbiting each of the two giant planets.
How do you spot a satellite?
Watch the sky closely in the dawn or dusk hours, and you’ll likely see a moving “star” or two sliding by. These are satellites, or “artificial moons” placed in low Earth orbit. These shine via reflected sunlight as they pass hundreds of kilometres overhead.
Can we see satellites at night?
He said satellites can be seen during twilight, early evening and really late at night right before morning twilight when satellites in low orbits can be seen.
Do satellites collide?
There have been no observed collisions between natural satellites of any Solar System planet or moon. Collision candidates for past events are: The objects making up the Rings of Saturn are believed to continually collide and aggregate with each other, leading to debris with limited size constrained to a thin plane.

How do I launch a satellite?
All satellites are launched to space and into their orbit by hitching a ride on a rocket or on the Space Shuttle, where they are placed inside the cargo bay. There are also countries and large corporations that have their own rocket launch facilities, so they can easily send their own satellites into orbit.
What are facts about satellite?
A satellite is an artificial object that is deliberately sent into orbit in space, usually in order to send, receive or bounce back information to different areas of Earth.
