One, dubbed HD 40307g, weighs at least seven times more than Earth and orbits the star on a 200-day "year" in the region amenable to liquid oceans on planets.

Around 7 times the Earths mass.

I saw a small blurb on this on my newsreader, and then forgot. Good catch Nem, and very interesting.

I wonder if they can distinguish between a planet and a binary planet in the low mass ranges yet.

Assuming it has a rocky surface, how much would we weigh there? Seven times earth? I need to go a diet....

Not enough data to say.  Mars 10% Earth mass 38% gravity.  The moon 1.2% earth mass 16.6% gravity.
