19 Ago. 2024: Mochejska et al. (2006) reckoned TR1 too large to be a planet because of its bloated radius (1.66 R_Jup). Subsequent detection of inflated hot Jupiter planets even larger than 1.9-2 R_Jup should lead to reconsider this transiting planet candidate. To date no mass estimate has been provided.
The latest comment on this exoplanet candidate is by Libralato et al. (2016), who assume it to be more likely a binary with a grazing eclipse rather than a transiting planet.
