New map shows exoplanets and size compared to Earth

TUCSON, AZ (Tucson News Now) -

This large poster shows all exoplanets discovered by October of this year and the size of them relative to the size of Earth.

Exoplanets are planets beyond our own solar system (the sun through Pluto). Thousands of exoplanets have been discovered in the past two decades, mostly with NASA's Kepler space telescope. These planets come in a huge variety of sizes and colors. Some are very large planets hugging close to their parent stars; others are icy, some rocky and some are super small, similar to Pluto.

You'll find Earth in the cluster of small planets, towards the left side, below the N in EXOPLANETS (title of map). Jupiter and Saturn can be found on the left side toward the bottom of the poster, you can clearly see Saturn and it's rings toward the corner. Finding these will give you a good example of how small Earth is compared to some other planets we have discovered.
