ExoWorld Selection Complete – Next Up, Obtaining Name Suggestions!
As you are likely aware, Planet Hunters is taking part in an IAU (International Astronomical Union) project to name several ExoWorlds. A few months back we provided the IAU a list of ExoWorlds which we thought should be named. The IAU took this list, plus all of the lists provided by other groups and determined which ExoWorlds will be named. In total, 15 stars and 32 planets will be named. The list:
| Host Star (catalogue) | # Planet (designation) | Planet Mass (Jupiter mass) | Planet Mass (Earth mass) | Orbital Period (day) | Semi Major Axis (au) | Discovery (year) | Constellation (English) | Visibility | V magnitude |

At this point, Planet Hunters can submit one naming suggestion. A suggestion consists of the name for one star, all attached planets and the basis for this recommendation. We are working to set up a Google form to select submissions and then we will have a round of voting to select the candidate to be submitted. This will all take place prior to May 31, 2015.
