An optical double are two stars that appear to be close together from our perspective on the earth but are in reality far apart and not binary stars.

Mostly, because stars are SO far apart! However, we have seen two stars that are so close together that one is stealing mass right off of the other star. If two stars were to actually collide, they would cause an explosion very much like a supernova.
The moon subtends an angle from earth of approximately 1/2 degree. Stars twice as far apart as the diameter of a full moon would therefore be 1 degree apart. Your fist at arm's length subtends approximately 10 degrees. So two stars three fists apart would be about 30 degrees.

Even when two landforms are far apart, the same types of processes that create and affect landforms apply.
two inches apart
depends on the scale of the map...
Electrical forces would push them apart.
They can be any distance apart depending on the focal length and magnification.
The two cities are about 210 miles apart, about 270 miles by road.A typical driving time is 4 hours.About 500 km
Two successive index contours on a map would be 5 meters apart. The interval is how far apart two contour lines are, so since the contour interval is 5 meters the answer is 5 meters.
