Object circles the earth 1,000,000,000 times Earths Rotation would that change the length of a day

Question

if it was done on the equator

Answer 1

it depends on its mass. if it was a sub atomic particle, then probably not, but if it was the size of the moon, then yes dues to tidal forces. in fact, the moon is currently slowing the earth down, but its effect is so small, we cant measure it in our lifetime

Answer 2

strictly speaking... No.  

However, the tidal effects of the object may have an effect.  (The moon, for example, is slowing the Earth's rotation).   If the object was moving at 1,000,000 times faster than Earth's rotation rate, however, the tidal effect would be very small to non-existent.  

Answer 3

It would, but the degree depends on the mass.  If the item was the mass of a beer can, it could go around forever and make no observable change.  It has been suggested that using an asteroid in an orbit that would bring it close to earth on a regular basis would gradually move the Earth away from the sun.  This is useful since the sun is gradually brightening and in only a billion years life on the surface of this planet will become extinct.  Of course if you s***w up the Earth is toast.  

Answer 4

Yes.  And the more mass it has, the more effect it will have.

The Moon slows the Earth's rotation through tidal effects.

But check out where it will have to be to have a 2,737,850 year orbit.  The Sun and other planets will perturb it.  Maybe even passing stars.
