In re-reading materials on the topic of special relativity, I have noticed something that passed my attention previously. Within the inertial reference frame, the mass of test particles isn't necessarily dependent on how they will behave in relativity. An astronaut will float in a spacecraft as well as a drop of water will. However, the inertial reference frame varies depending on the total mass of the object. For example, a scrap bolt orbits the Earth closer than a spaceship when traveling at the same velocity. Likewise with the moon if it too traveled at that velocity. So the inertial reference frame depends on its mass if I am not mistaken. Does this mean that relativity must be considered in terms of mass, velocity and time?

The inertial reference frame is x[itex]^{2}[/itex]-t[itex]^{2}[/itex] = x'[itex]^{2}[/itex]-t'[itex]^{2}[/itex]

Mass doesn't matter in these frames, however it does affect where the frame is located in an orbit. So, is the inertial reference frame dependent on mass? Can it be explained why, if not? If mass does effect the inertial reference frame, what might that effect be?

Thanks
