Communication satellites must be in a fixed position in relation to the earth so that a dish can be in a permanent position aiming at the satellite. Satellites must travel approximately 17,000 mph to maintain their orbit. To be in a fixed position in relation to earth and traveling at 17,000 mph, they must be high.
Just the way it is.
Comment: Maybe, but it probably has something to do with gravity. Well spread out planets have only small gravitational effects on each other.
That should help their orbits to remain stable.
Because so many of them have been launched, and ... for perhaps the
past 30 years ... most launches produce a successful orbital insertion.

Satellites are expensive to build, and REALLY expensive to launch. Every one has a purpose.
Some are military in nature; communications, electronic surveillance, orbital imagery.
Many are commercial; TV satellites, communications relay satellites, weather imagery, cell phones.
Some are more fun or enjoyment related; there's the old OSCAR satellites built by HAM radio operators, and piggybacked into space because the booster had some excess capacity. College students, and even some high schools, are building "cube-sats" that are boosted into orbit as hitchhikers.
Once they're up there, they generally stay up there unless they were launched into fairly low orbits.
There are probably millions of them. We have only found one so far. The problem with inhabitable planets other than the Earth is they're so far away.
it is 5,578 miles away
it has taken pictures of far away galaxies, stars, and planets.
Yes, they can have planets but they will not be as common as a single star system. If any planets are formed, they will generally be far away from the stars. This is because of the gravitational influences of two stars. This instability prohibits the formation of planets. Obviously, it depends on the mass of the two stars and their distance from each other. A close pair will probably not have planets whereas a major star and a far minor binary pair will not experience the same influences and planet formation could occur without the same constraint's. Our nearest binary/triple star system - Alpha Centauri has yet to have any planets detected.
Because solar can absorb higher sun rays
Not as far apart as stars are from each other, but yes, they are a long way apart.
How far away is Pluto from all the pther planets?
Maybe life on planets far far away!
far away
how far planets are each other and where they are . :)
It will vary from planet to planet but they will all be aligned in a straight line. The distance from Earth to Mars will be about 33,900,000 miles.

because there is no air and the other planets are far away to visit.
The planets reflect sunlight, but the stars are too far away to have any significant effect.
sorta there are inner and outer planets the inner planets are alike and outer planets are alike to but inner and outer planets are different.
