We see like a star, at night, which moves from one to other side, is it something man made or else.

I have been watching something in the sky since 2002 that jumps around and it gets bigger and smaller like it is coming forward and moving back.
I looked at it through my telescopic lense of my camera one time and it had two golf ball looking things one pink and one blue and they each spin. Then there is a triangle over them and some fiber optic looking dots under it.

People from across America call into coast to coast with George Noory and say they see this too.
I think it has to be man made.

If you can read the writing on my avatar, you can see that I worked for NASA during the Apollo XI mission. First of all, I wouldn't call a light in the sky a star because it could be virtually anything: natural, man-made, or made by some other civilization. I've heard people say they saw a shooting star or a falling star and, believe me, if a star fell around here we would all be long dead before it ever hit us.

Actual motion of an object in the sky can be quite different from the apparent motion. An object may be in an orbit that makes it look like it is changing size when it really only changing in distance from the Earth. If the apparent changes in an object are regular enough so that they can be predicted, it is likely in orbit around, or being affected by, some other body, perhaps an object we can't see.

There is no way to tell what the object you are describing might be. If you look at some of my other posts concerning the Apollo XI mission and quoting NASA scientists and astronauts on this subject, I think you will be shocked.

Probably one of many many human made satellites that orbit the planet.
