WASP-195 b: Less Dense Than Cork
Ice giant around WASP-195
It is 0.92 times Jupiter's radius, closest in size to Jupiter, and 33.1 times Earth's mass, at 0.16 g/cm3, less dense than Earth. A year there lasts 5.05 days, on an orbit 6 times closer to its star than Mercury is to the Sun. Its equilibrium temperature is 1522 K, hot enough to vaporise rock. The host star WASP-195 runs at 6300 K with 1.30 times the Sun's mass.

What the transit gives
The depth of the dip is the ratio of the two discs, so the radius follows.
Two independent measurements sit behind this page: a dip in starlight for the size, and something else entirely for the mass. Together they make a density.
