The last votes are nearly cast, get in before it is too late! On October 31, the IAU is closing voting on NameExoWorlds.org. So make sure to case your vote.
Planet Hunters submitted a naming option for PSR1257+12 (Photo, Lofio, Xekiní̱ste, Amydrós) please help us by voting!
Thank you to everyone who has participated up to this point! The votes have been counted and Planet Hunters has submitted the following naming suggestion to the IAU ExoWorld naming contest:
- PSR 1257 12: Photo – Photo is the Greek word for light. Since it is a pulsar that releases two beams of light, Photo would be suitable as a name that emphasizes the beams of light the pulsar emits.
- PSR 1257 12b: Lofío – Since b is the least massive exoplanet ever discovered, the Greek word for a plume fits. Naming the least dense exoplanet after a feather honestly seems suitable.
- PSR 1257 12c: Xekiní̱ste – Since this is one of the first exoplanets discovered, the Greek word for start fits. This name signifies the start of a new era in finding planets outside of our solar system.
- PSR 1257 12d: Amydrós – Since it is the outermost planet in the system, it has the longest orbit; it blocks the light beams the most. So for that reason, the Greek word for dim fits, as it dims out the pulsar beams the most.
A hardy congratulations to Trent Crespo is in order. It was his name that was decided on by this community to put forward!
Our work is not done though – shortly in June 2015 a sign-up window will open for individuals to register to vote for the IAU naming selection. Watch http://www.nameexoworlds.org/#signup for this window to open!
The group has done a fantastic job voting so far! For the final days of this vote, I have narrowed down the list of options to the top 4! This four options had greater than 10% of the vote. The voting page has been updated once again and we are asking you to select one naming suggestion for us to move forward to the IAU. If you voted previously, you can vote again. Voting for this round will be ended on May 15, 2015, so please vote promptly!
On April 16, 2015, the gavel was slapped on round 2. The naming suggestions were reviewed by Planet Hunter moderators for conformance to the IAU criteria and in all the community had generated 33 naming suggestions that appear to conform. Now it is time for round 3! The voting page has been updated once again and we are asking you to select one naming suggestion for us to move forward to the IAU. Voting for this round will be ended on May 15, 2015, so please vote promptly!
In the blog post earlier today, I reported that phase 1 was complete – the IAU (International Astronomical Union) has selected the stars to be named. Phase 2 involves groups providing naming suggestions for the star and all attached planets. The “Vote” button has been updated with a new form to begin taking these suggestions from Planet Hunters! Please provide your naming suggestion by April 16, 2015.
After April 16, 2015, the Planet Hunter’s moderators will review the suggestions for conformance to the stated guidelines for naming suggestions and a poll will be set up for us to select our one naming suggestion that will be put up. So start your suggesting!
Proposed names should be:
- 16 characters or less in length.
- Preferably one word.
- Pronounceable (in some language)
- Not too similar to an existing name of an astronomical object. Names already assigned to astronomical objects can be checked using the links http://cds.u-strasbg.fr/cgi-bin/sesame (for galactic and extragalactic names), and the MPC database http://www.minorplanetcenter.net/db_search (for names)
In addition it is not allowed to propose:
- Names of pet animals.
- Names of a purely or principally commercial nature.
- Names of individuals, places or events principally known for political, military or religious activities.
- Names of living individuals.
- Only names that are not protected by trademarks or other forms of intellectual property claims may be proposed.
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:

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.
This is exciting! The International Astronomical Union (IAU) is working Zooniverse, astronomical clubs and the public at large to name some number of exoworlds and host stars. Some of the work has already been done, some work is yet to do. The exciting part is that Planet Hunters will be assisting in some of the next steps! Let’s break down their milestones:
- July 2014: IAU compiled a list of 305 exoworlds confirmed prior to December 31, 2008 as candidates for naming.
- October 2014: The IAU opened http://www.nameexoworlds.org to permit astronomy organizations to register to take part. Planet Hunters completed this and was confirmed!
- January 2015: Planet Hunters, along with other clubs, will vote for the ExoWorlds they wish to name out of the list provided by the IAU.
- February 2015: Planet Hunters, along with other clubs, will send in proposals for the names of members of these selected ExoWorlds (including the host star), based on the rules in the IAU Exoplanet Naming Theme, together with a detailed supporting argument for their choice. Each group is allowed to name only one ExoWorld. More details on this stage will be given later.
- June 2015: the general public votes to rank the proposed names.
- July 2015: the IAU, via its Executive Committee Working Group on the Public Naming of Planets and Planetary Satellites, oversees the final stages of the contest, and validates the winning names from the vote.
- 3–14 August 2015: the results are announced at a special public ceremony held during the IAU XXIX General Assembly in Honolulu, USA
We are in the January 2015 milestone. You may have noticed that there is a new “Vote” button on the Planet Hunters classification ribbon. This button takes you to a poll which has been set up to collect Planet Hunter community input. We want your participation! So let’s name an ExoWorld!!!
