Overview
: "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." The database stopped being updated in mid-2018 and is no longer actively maintained. ==See also==
