There is currently a debate over the classification of this object as either a planet or a brown dwarf. One of the leading astronomers in this discussion is Christopher Johns-Krull, who indicated that the debate is still quite lively. This is not particularly unusual or strange, as it would not be the first of many brown dwarfs orbiting mother stars.
The light curve that better match the steepness of ingress and egress implies a planetary radius of 1.32 ± 0.15 RJ and a mass of 11.71 ± 0.46 MJ.

Famous quotes containing the word debate:
“Abject flattery and indiscriminate assentation degrade, as much as indiscriminate contradiction and noisy debate disgust. But a modest assertion of one’s own opinion, and a complaisant acquiescence in other people’s, preserve dignity.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
“Like man and wife who nightly keep
Inconsequent debate in sleep
As they dream side by side.”
—Robert Graves (1895–1985)
“My first debate in high school—”Resolved: Girls are no good”—and I won!”
—Donald Freed, U.S. screenwriter, and Arnold M. Stone. Robert Altman. Richard Nixon (Philip Baker Hall)
