ROXs 42Bb is a directly imaged planetary-mass companion [1] to the binary M star ROXs 42B, [4] a likely member of the Rho Ophiuchi cloud complex. The companion was announced/discovered on October 17, 2013, by University of Toronto astronomer Thayne Currie .
The sizes are listed in units of Jupiter radii (R J, 71 492 km).This list is designed to include all planets that are larger than 1.6 times the size of Jupiter.Some well-known planets that are smaller than 1.6 R J (17.93 R 🜨 or 114 387.2 km) have been included for the sake of comparison.
−0.4 × 10 −4 times as luminous as the Sun (L ☉). [ 21 ] Despite the uncertainty of the planet's properties, a 2017 study calculated HD 100546 b as a very highly reddened substellar object with a good-fit effective temperature of 2,630 K and a planetary mass and radius of 25 M Jup and 3.4 R Jup , making it still one of the largest ...

The bright burst of electromagnetic radiation may be brief, but fast radio bursts are so powerful that they produce more energy than what our sun emits in an entire year, astronomers say.
Thus ROXs 42 Bb, GQ Lupi b and HD 100546 b might actually be brown dwarfs. Thus it would be improper to say that they are the biggest planets, and CT Cha b (316 000 km) will get the record for now. --Joey P. - THE OFFICIAL 03:35, 14 July 2017 (UTC) No. HD 100546 b, ROXs 42Bb and GQ Lupi b are planets because they are not massive enough.
