The object must move with the speed of 
times to approximately seeing that it is contracted to exactly half of its actual length.
<h3>How is this calculated?</h3>
The length contraction experimented by the object as it approaches lightspeed, in meters per second, is described by Lorentz contraction formula:
Here, v is the current speed m/s
c is the speed of light in m/s
L' is the length of the object at rest in m
L is the length of the object at the current speed in m
Now we know that
and 
then,
Hence, r = 
Therefore, the answer is the object must travel at a speed of times the lightspeed to be contracted to one-half its proper length.
