Hi Frank,

Oliver Kloes, now at IOTA ES http://www.iota-es.de/light_poll.html, once provided an exoplanet list / plugin.
You can find it in "Extras \ Toggle User Data \ Planetary Systems".
AFAIK however, the last update goes back to August 10, 2005 (!): http://www.projectpluto.com/explanet

Perhaps you could contact him ?

Regards

Roger
