Earth-sized Planets

Kepler 20 System
Kepler 20 System

We have finally discovered two planets outside our solar system that have roughly the same size as Earth. Unfortunately, unless we learn that life can exist in the form of fire beings, these two planets are too close to their sun to support life. Their temperatures are in the hundreds and thousands of degrees. A bit balmy.

The New York Times has a small but interesting chart that fits inline with its article, at least on its website—presumably it fits similarly in its printed form. Seen here to the left, it plots the orbital distance of the planets that are known to orbit the star Kepler 20. (Unfortunately these planets have less than creative names: Kepler 20e and Kepler 20f.) The other planets are gas giants.

The use of scale of orbits and the gap between 20f and 20d allow for an annotation within the image. And then with a little bit more vertical space, to drive hom the point of these new planets’ nearness to their sun, the orbit of Mercury, the planet nearest our sun, is plotted for comparison.

I am a graphic designer who focuses on information design. My day job? I am the data visualisation manager for the Federal Reserve Bank of Philadelphia. (This blog is my something I do on my own time and does not represent the views of the Fed, blah blah blah legal stuff.) And with my main interest in information design—be it in the shape of clear charts, maps, diagrams, or wayfinding systems—I am fortunate that my day job focuses on data visualisation. Outside of work, I try to stay busy with personal design work. Away from the world of design, I enjoy cooking and reading and am interested in various subjects from history and geography to politics to science to the arts. And I allow all of them to influence my work.
