We live in an extrodinary time of discovery. New technologies and measurement techniques have allowed scientists to map an increasing number of exoplanetary bodies. While the vast majority we have located are gas giants, we are now finding out that small ones are actually more common. While we know very little about these planets and what is on them, we are on the verge of a new flood of information thanks to more advanced telescopes.

The planisphere is a small map consisting of two circular overlays that display the visible night sky. Each layer is rotated to match the current month and time to reveal what is in the sky during that time.

Traditionally, they mapped out stars and constellations. However, this piece has been modified to include major constellations and locations of exoplanets. Each star that a planet circles around is represented on the chart, as well as the orbits of the planets around those stars. The orbits are not actual paths of the planets, but rather a visualization of planet types and number of planets circling a particular star. To this extent, the map functions as both map and data visualization of discovered exoplanets.
