This poster aim's to get viewers interested in the nights sky, the stars around us and our position amongst them.

Below is the text which features in the lower half of the poster:

To understand this diagram, try to imagine you are looking towards the Sun from a great distance (beyond 12 light-years). The stars surrounding the Sun have been plotted using their angular position from the celestial equator which is actually the Earth’s Equator projected onto the night’s sky.

The measurements in the scale above are for distances parallel to the declination plane. However, none of the featured stars are exactly on this plane, and as a result, distances appear shortened. For example, Ross 248 might seem closer to the Sun than Luhman 16, but it is actually 3.8 light-years farther away!

It is worth noting that the stars closer to the viewing point have been increased in size. So stars that are farther away, beyond the Sun for example, will appear smaller. This is not an accurate depiction of the featured star’s size, just a useful guide for their position in space.

Star Systems
Many of these stars are actually binary star systems, meaning they are multiple stars orbiting each other. The universe is full of such star systems. For example, Alpha Centauri actually consists of two stars; Alpha Centauri A and B. However, when viewed from Earth, they appear to be one and have been mapped as such.
