This allows the measure of angular distances between astronomical bodies.
O, 11 freedom from the limitation of angular distance would be 12 delicious.
It is the asteroid discovered in the smallest angular distance from the sun ( 53,5 degree ).
The proof can be extended to show that the points on a circle are all a common angular distance from one of its poles.
As the angular distance from the guide star increases, the image quality degrades.
These instruments are also used to measure the angular distance between objects:
This yields the angular distance between the two objects.
The expression "perhaps a few inches" therefore suggests an angular distance in the order of one degree or less.
Measurements of angular distance can also be made with an instrument called a sextant.
The figure to the right represents the three angular distances.
