The Exoplanet Explorers Encyclopedia

EMBARGO: This project is under development and it does not have yet a release day. The information shown here is only for collaborators. Please do not share the link to this page.


There are many databases tracking the discoveries of planets around other stars (exoplanets). All these databases include the physical properties of these planets and their parent stars. However, none of those are focused in the scientists, institutions, observatories, and countries behind these discoveries. The Exoplanet Hunter Catalog (EHC) will be the first database in the world to list and organize this information, including findings statistics and discovery metrics. The EHC is expected to be used as a tool to inform and stimulate the general public, and track the performance of discoverers, institutions, and countries in this field of astronomy. This project is a collaboration of the Planetary Habitability Laboratory @ UPR Arecibo, the Metropolitan University, and the Arecibo Observatory.


  1. Create a database of confirmed exoplanets with their discoverers, institutions, observatories, and countries.
  2. Construct an index to rank the discoveries.
  3. Compare statistically the discoveries.
Database Fields

  1. Planet Name
  2. Author Name
  3. Author Last Name
  4. Author Rank Number (i.e. 1, for first author of the paper)
  5. Institution Dept./Div. Name
  6. Institution Name
  7. Institution City Name
  8. Institution Country Name
  9. Observatory Dept./Div./Inst. Name (if any)
  10. Observatory Name
  11. Observatory City Name
  12. Observatory Country Name
  13. Project Name (name of the exoplanet search project, if any)
  14. Discovery Date (MM/DD/YYYY of published paper)
note: some author list multiple institutions and observatories

Expected Outcomes

  1. Full database of the discoverers, institutions, observatories, and countries (comma-delimited file).
  2. Top 10 Exoplanets Hunters Scientists (list, includes scientist photos).
  3. Top 10 Exoplanets Hunters Institution (list, includes institution logos).
  4. Top 10 Exoplanets Hunters Observatories (list, includes observatory logos).
  5. Top 10 Exoplanets Hunters Countries (list, includes country flags).
  6. Top 10 Exoplanets Hunters Discoveries (list, includes author name, institution logo, country flag).
  7. Global Map of Countries with Exoplanet Discoveries (image and time animation, 1992 to present).
  8. Infographic of the Flags of Countries with Exoplanet Discoveries (includes number of exoplanets in each).
  9. Exoplanet Hunter Index (EHI) (one or more metrics to rank the discoverers).
Other Ideas

  1. Cross reference EHC with other exoplanets catalogs.
  2. Find the countries that discovered the planets that are biggest, hottest, habitable, etc..
  3. Include nationality, country of origin, current institution, or contact information for authors.

    Example (for first entry of Top 10 Exoplanets Hunters Discoveries)

    Aleksander Wolszczan [alɛkˈsandɛr ˈvɔlʂt​͡ʂan] (born 29 April 1946 in Szczecinek, Poland) is a Polish astronomer. He is the co-discoverer of the first extrasolar planets and pulsar planets.

    Working with Dale Frail, Wolszczan carried out astronomical observations from the Arecibo Observatory in Puerto Rico which led them to the discovery of the pulsar PSR B1257+12 in 1990. They showed in 1992 that the pulsar is orbited by two planets. Their orbits are 0.36 and 0.47 AU respectively. This was the first confirmed discovery of planets outside the Solar System.
