After the discovery of the first confirmed exoplanet 51 Pegasi b in October 6, 1995, astronomers have been able to detect and confirm over 4000 planets orbiting around nearby stars in recent years. It is now believed that most stars have planets orbiting around them, with some of them being Earth-like in characteristics.

The International Astronomical Union (IAU), as part of its 100 years celebration, opens the NameExoWorlds competition to all countries.
After the 19 exoplanets named in the first NameExoWorlds competition in 2015, the IAU will now offer every country a chance to name one planetary system, comprising an exoplanet and its host star. The IAU is the authority responsible for assigning official names to celestial bodies, and through the coordination with each country's National Committee host the local NameExoWorlds competition.

The National Committee for the Philippines invites every Filipino citizen to propose a name for the exoplanet and its host star in adherence to the IAU naming rules.
The Philippines is assigned the WASP-34 system which is found in the constellation Crater. In recognition of the International Year of Indigenous Languages 2019 the IAU encourages all speakers of indigenous languages to propose names drawn from those languages. The Philippines is host to a rich diversity of languages and dialects and as such the national committee encourages the submission of names in these languages. The top 3 name pairs from the local competition will be submitted to the IAU NameExoWorlds Steering Group for validation and final selection.

WASP-34 & WASP-34 B

WASP 34 is a yellow (G5) star located at 120pc (391.2 light years) ± 15pc, in the constellation Crater "the cup". It has an apparent magnitude of 10.4 which makes it visible to some binoculars and most small telescopes (at least 50mm aperture, with favorable viewing conditions).

Orbiting WASP 34 is a planet, roughly the size of Jupiter, called WASP-34 B. It was discovered transiting WASP 34 through the Wide Angle Search for Planets (WASP) in 2010. The planet orbits close to its parent star (in contrast to the solar system it is somewhere in between the orbit of Mercury and Venus).

The WASP 34-B and WASP 34 is the exoplanet system assigned to the Philippines by the IAU for the NameExoWorlds competition


Crater is a Southern Sky constellation located next to Hydra and Corvus. It's name means "the cup". In Greek mythology Crater represents the cup of Apollo (usually depicted as a two-handed chalice) and is part of the story of Corvus. The god Apollo needs water to perform a sacrifice ritual so he sends the Raven/Crow (constellation Corvus) to fetch water with his cup. The bird gets distracted by a fig tree and spends a few days waiting for the figs to ripen. Eventually the bird returns to Apollo with the cup and a water snake (Hydra) to serve as an excuse for its delay. Seeing through the bird's deceit Apollo angrily cast the three into the sky and cursed the bird by burning its feathers and making it eternally thirsty. This resulted to the black wings and raspy voice of crows and ravens.

Crater is best observed from March-June. Three of Crater's stars have known planets. Being away from the galactic plane it is host to a few galaxies like NGC 3887 and NGC 3511. There are no Messier objects in Crater.
