Exoplanet Data Explorer

The Exoplanet Data Explorer / Exoplanet Orbit Database lists extrasolar planets up to 24 Jupiter masses.〔(The Exoplanet Orbit Database ), Jason T Wright, Onsi Fakhouri, Geoffrey W. Marcy, Eunkyu Han, Ying Feng, John Asher Johnson, Andrew W. Howard, Jeff A. Valenti, Jay Anderson, Nikolai Piskunov〕〔(Catalog of Nearby Exoplanets ), R. P. Butler, J. T. Wright, G. W. Marcy, D. A Fischer, S. S. Vogt, C. G. Tinney, H. R. A. Jones, B. D. Carter, J. A. Johnson, C. McCarthy, A. J. Penny, The Astrophysical Journal, Volume 646, Number 1, 2006〕
: "We have retained the generous upper mass limit of 24 Jupiter masses in our definition of a “planet”, for the same reasons as in the Catalog: at the moment, any mass limit is arbitrary and will serve little practical function both because of the sin i ambiguity in radial velocity masses and because of the lack of physical motivation.

: The 13 Jupiter-mass distinction by the IAU Working Group is physically unmotivated for planets with rocky cores, and observationally problematic due to the sin i ambiguity. A useful theoretical and rhetorical distinction is to segregate brown dwarfs from planets by their formation mechanism, but such a distinction is of little utility observationally."〔
