We have completed an English translation of our website on exoplanets at Paris Observatory. It provides a comprehensive description of exoplanets and of the ways astronomers detect them, from simple questions to the astronomer's toolbox.

A database of already detected exoplanets (based on the Encyclopedia of extrasolar planets data) is included, together with interactive simulations (2D and 3D sky maps, planetary orbits).

The French version also includes a section on the CoRoT mission, but the translation for this part is still ongoing.

Great site, lots of cool features! Two comments:

1. Excentricity is spelt "eccentricity," it's misspelled on the statistics page.
2. I would add discovery date to the planet database, it would be nice to be able to see which planets were discovered the most recently.

Ooops ! Thanks for the report, I fixed that right away.

I thought about that, but then it's often difficult to provide a "discovery date", since often discoveries are uncertain or partial and the complete information has been "discovered" over the course of many years. If you take a look at the "Planets in history" theme, you will see some examples.

That being said, there is a "discovery year" given in the extrasolar planets encyclopedia, so you could take a look at it there :

Very cool website. I love the 3-D star map!!!

Excellent site. I noticed in the "What is an exoplanet?" section, you refer to the inner planets as "telluric". I suppose this is technically correct, but the more commonly used term in English (at least here in the states) is "terrestrial" (which means about the same thing).

I like the site but it has some problems and I was unable to find a feedback button to advise the webmaster. The contact listed in the contact section is in a bitmap and so you need to manually type the address into a mailer to contact them, don't know if that is deliberate or not. Either way a webmaster should be listed just for website stuff.

Nice website. However, the percentage reported in the how many exoplanets are there section in our galaxy is incorrect. It says that 7% of stars have gas giants with periods of ten years or less. Here is recent paper (astro-ph/0702213v1) written by Marcy et al which gives an updated percentage:

"Thirty planets have now emerged from the 260 target stars of the AAPS, suggesting that 10% of late F, G, and K field dwarfs have planets that can be detected with Doppler precisions of 3ms−1 and a time baseline of 8 years (a similar detection rate to that of the original 106 stars on the Lick Observatory survey which has yielded 13 planets to date; Fischer et al. 2003). These surveys are now beginning to explore planets in orbits beyond 4AU, though they remain insensitive to terrestrial mass planets beyond 0.1AU and neptune-
mass planets beyond 1AU. However, with planets being found orbiting more than 10% of nearby sun-like stars, it seems that planetary systems are common."

Also, microlensing searches are 90% confident that somewhere between 16-69% of galactic M-dwarfs have 10Me planets between 1.5 and 4 AU.

Thus, your website needs to update the 7% percentage for the fraction of stars with planets.
