Can anything truly be stationary in our constantly moving universe?

[shinnsohai]

As you may know, our planet(Earth) , solar system, galaxy are moving in a very fast speed traveling around the universe
but, whenever a satellite being launched out from earth, and it's stationary means no speed
then will it be left behind ??

There is no absolute velocity in the universe. Only velocities relative to something else.
Satellites start with zero velocity relative to the Earth and gain a small velocity (~8km/s) relative to it - just enough to orbit it. Therefore, they stay in an orbit around earth. The speed of (earth+satellite) relative to anything else does not matter.

this seems interesting !
so even we're in stationary, we're moving with 8km/s
cool!

Okay my curiosity solved !
:D

Much more, depending on the view. Earth is moving around the sun with 30km/s (relative to the sun). The solar system is moving around the galactic center with ~200km/s (relative to the galactic center). Relative to the cosmic microwave background, we are moving with ~400km/s.
Relative to high-energetic cosmic rays, we are moving with more than 99% of the speed of light ;).
