binary star are 2 stars that circle around each other traveling in space and Opitcal double are 2 stars that appear close tpgether, but are really far apart.
Each of those is an eclipsing binary.
A binary star is a star system consisting of two stars orbiting around their common barycenter. Systems of two, three, four, or even more stars are called multiple star systems. These systems, especially when more distant, often appear to the unaided eye as a single point of light, and are then revealed as double (or more) by other means.
Mizar is a binary star system consisting of two stars, Mizar A and Mizar B, located in the constellation Ursa Major. Alcor is a nearby star that appears as a single point of light with Mizar, forming an optical double star. Both Mizar and Alcor are composed primarily of hydrogen and helium, like other stars.
A pair of stars that appear to form a double star but are not physically related is called an optical double. These stars only appear close together from our perspective on Earth but are actually at vastly different distances and are not gravitationally bound to each other.
A double star is a pair that appear very close together in the sky, but that might be by chance and one of them might in fact be a lot further away than the other. A binary star is a special type of double star in which the two components are in orbit around their common centre of gravity.
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.
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.
The difference between a double wide and a manufactured home is that the manufactured home is put on a foundation.

The difference between a double room and a double standard room is the double often contains two beds. A standard double has just one bed and is designed for two people.
The idea is to first do the subtraction, then multiply the result by 2.
they have no difference.. they are same
I don't think there is a difference.
