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 ...

Comparison: the Sun (yellow), a young sub-brown dwarf (red), and Jupiter (multi-colored). As the sub-brown dwarf ages, it will gradually cool and shrink. A sub-brown dwarf or planetary-mass brown dwarf is an astronomical object that formed in the same manner as stars and brown dwarfs (i.e. through the collapse of a gas cloud) but that has a planetary mass, therefore by definition below the ...
It's flu season right now, and the U.S. is in the midst of a wave that's straining hospitals.But not all influenza is the same. There are some notable differences between flu A and flu B strains.
