Quantos exoplanetas se conhecem?

Actualmente 335. Mas vai haver mais. Informação recebida da Planetary Society:

You can keep track of the growing number of exoplanets with the new Planetary Society online Catalog of Exoplanets.

With the successful launch of Kepler – NASA’s exoplanet-finding spacecraft – and ESA’s Corot already in orbit, our Catalog of Exoplanets will be particularly useful for keeping up with the many new upcoming discoveries from space and from the ground.

The Catalog features an up-to-date list of all known exoplanets, along with essential information about each, such as each planet’s

• location and home star
• mass
• orbital period
• date of discovery
• and the method by which it was detected

There is also a wealth of additional information about each planet and parent star, plus animated graphics for each exoplanet showing its precise orbit and that of any other known planets in the system.
