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.

Even when two landforms are far apart, the same types of processes that create and affect landforms apply.
depends on the scale of the map...
two inches apart
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.
The term used to describe how far apart two locations are is "distance." Distance can be measured in various units such as kilometers, miles, or meters.
Electrical forces would push them apart.
Two stars in a binary star system are most likely 4 light years apart. Binary star systems are common in the universe and consist of two stars that orbit around a common center of mass.
