Hello!

Can you tell me please some basic values for satellites?
How much energy/cost we need to send a satellite per ton? Is there a maximum weight limitation?

thanks!

SpaceX lists payload sizes and costs for their rockets. Costs are usually low few thousands of dollars per kilogram to orbit, but it depends on all kinds of things such as how high the orbit is; geosynchronous orbit costs about three times as much as low earth orbit, also the plane of the orbit you want. I forget what the maximum SpaceX payload is currently supported, maybe 50 tonnes-ish, depending on how many boosters they stick on and so forth. If you had a big wodge of money they'd be only too glad to build a much bigger rocket for you though. There's no particular maximum size, thousands of tonnes could probably be launched, but on the low side, less than a few hundred kilograms or so, the cost goes sky-high.

If you have a small payload, you could look at a CubeSat, with a maximum size of 10cm x 10cm x 10cm.

If you don't particularly care what orbit it ends in, they can often be squeezed onto an existing launcher, if the primary payload doesn't use the entire lift capacity of the launcher.
