Camelopardalis

The author always had difficulty remembering the entirety of Camelopardalis' name, and it may be helpful to note that it symbolises a giraffe. Camelopardalis is a large but faint constellation, ranking 18th in terms of area with its brightest star only of fourth magnitude. Interestingly, Voyager 1 is moving in the direction of Camelopardalis, though naturally its power source will be dead by the time it nears any of the stars in this constellation.

This is a rough drawing of Camelopardalis, with its neighbouring constellations.

Beta Camelopardalis, the brightest star, is a visual double. As its name indicates, it is a pair of stars that appears close to each other viewed from the Earth, especially with the aid of optical telescopes. This may be because they are either a binary star or is an optical double. An optical double are unrelated stars which simply appear close together. To confirm an optical double is a binary star, you can observe the relative motion of the two stars. If the motion is part of an orbit, or if the stars have similar radial velocities, they are likely to be binary stars. Radial velocity essentially denotes the speed in which a celestial object is moving away from Earth.
