XO-3b has a mass 11 times Jupiter.
Then there is TW_Hydrae_b at 9.8 Mj.

There is a nice chart here: http://en.wikipedia.org/wiki/List_of_stars_with_confirmed_extrasolar_planets

and you can look up each individual exoplanet like here: http://en.wikipedia.org/wiki/XO-3b

Xena is the nickname given to Eris, the dwarf planet discovered just beyoud Pluto…

   We probably haven’t seen it yet… There are so many planets out there.

   If we consider objects revolving around a star which have cleared their orbit as planets, then the brown dwarf (brown dwarfs are also classified as a stellar objects) revolving the star CM Draconis (M4) in the constellation Draco would probably be the biggest extrasolar planet. It has a mass of 64 Jupiters. Its designation or name is Draconis B

   However if we exclude brown dwarfs then here are several extrasolar planets that are real giants:

   (1). HD 202206b, mass of 17.4 Jupiters revolving around star HD202206 in the constellation Capricorn.

   (2). HD 168443C, mass of 17.1 Jupiters revolving around star HD168443 in the constellation Serpens Calida.

   (3). Planet HD 162020b. Mass of 13.73 Jupiters revolving around star 162020 in the constellation Scorpio.

   (4). Aldebaran B, mass of 11 Jupiters revolving around Aldebaran ( Alpha Taurus HD21939) in the constellation Taurus

   There are so many more extrasolar planets that have been confirmed with masses more than that of Jupiter, but the above would probably fit as the real giants. No definite names however have been given to these planets as they are not part of our solar system.

   There is also a star that is revolving around a bigger star. The star OGLE-2005-BRG-071 revolves around the star 170584. Its mass is estimated as 2453513 Jupiters.
