Doppler Shift......The wavelength of light emitted by a moving object is shifted. This effect is called the Doppler shift.
The question also reveals a poor understanding of 'moving'. Each object is it's own 'rest frame', and can only be moving with respect to something else specified, representing another rest frame.
For the purposes of real motion (and maximum speed c, including for the propagation of em waves) the reference is always the local background (frame).
(If you are timing a car go past at max speed v, then you accelerate to v', it does not mean the car can suddenly do v+v'!, so the speed is not with respect to anything except it's local background.)
The Special Theory of Relativity was valid for space that was empty (a perfect vacuum) and bodies that were perfectly rigid. We know know space is not empty and bodies are not rigid, but no other more valid or consistent theory has yet been adopted.

What two factors determine the kinetic energy of moving object?
velocity and mass
How do astronomers determine the speed at which a galaxy is moving?
By examining its spectrum, and identifying absorption lines in it. Lines are shifted toward shorter wavelength if the object is moving towards us. They're shifted toward longer wavelength if the object is moving away from us.
How can you determine the direction in which a comet is moving?
You determine it by were is it moving and when a bright streek is moving
What is the fastest moving object in sports?
A skydiver is the fastest moving object in sports.
Tendency for a stationary object to remain at rest or for a moving object to continue moving?
ammonia....'_'
How do scientists use isotopes to determine the of an object?
Scientists use the relative amount of stable and unstable isotopes in an object to determine its age.
What veritables determine how fast an object will be moving when it reaches terminal velocity?
The surface area is the variable to determine how fast an object will be moving when it reaches terminal velocity.
Determine if the momentum of an object moving in a circular path at constant speed is constant.?
determine if the momentum of an object moving in a circular path at constant speed is constant.
How do scientists determine how old objects are by?
Archeologists determine how old an object is, by using Carbon Dating.
How do you determine the speed of a moving object?
The average speed of an moving object is determined by using the formula velocity=distance/time or v=d/t.
Is the momentum of an object moving in a circular path at a constant speed is constant?
determine if the momentum of an object moving in a circular path at constant speed is constant.
What two factors determine the kinetic energy of moving object?
velocity and mass
What two factors determine how much kinetic energy a moving energy?
Do you mean "a moving object"? Then the answer is mass & speed.
In order to determine if an object is moving you must observe the object in relation to a?
. . .point of reference. For example, one can tell whether a planet is moving according to its position in relation to a star.
How can scientists tell if an object is moving away from our galaxy?
It makes a lower frequency than something coming to us
How is density calculated and how do scientists use it?
Density is mass divided by volume. Can be used to determine if an object will float in a liquid or not.
Which two factors can be caclulated to determine the kinetic energy of an object?
The kinetic energy of any moving object is one-half the product ofthe object's mass and the square of its speed.
