|
If it misses this window, further opportunities occur at intervals of 23 hours and 56 minutes a period known as a sidereal day. All this may seem a lot of effort to confirm a theory that most physicists assume is true. |
|
To track an object, the telescope's polar axis is driven smoothly by an electric motor at a sidereal rate namely, at a rate equal to the rate of rotation of Earth with respect to the stars. |
