exoplanets and dark matter?

[Reggie]

Hi all, so, what with another exoplanet being discovered, on it's own as insignificant as the earth with regard to mass, I was wondering how this would scale up with regard to current thinking on the amount of matter Vs dark matter out there?

I've seen reports in the 100 billion range for estimates of the number of stars in the milky way, will they have to revise down estimates on how much dark matter there actually is?

Whoops, that should read 'I've seen reports in the 100 billion range for estimates of the number of planets in the milky way'.

Probably makes much more sense now

Regards,

Reggie.
