:INFO
Ice giant around Kepler-82
It is 5.34 times Earth's radius, closest in size to Uranus, and 13.9 times Earth's mass, at 0.49 g/cm3, less dense than Earth. A year there lasts 51.54 days, on an orbit 1 times closer to its star than Mercury is to the Sun.

What the transit gives
Block a known fraction of a known star and you have measured a width.

:NOTE
The size came from a crossing, the mass did not. That pairing is uncommon and it is what lets anyone say whether this is rock or gas.

:NOTE
Found by Kepler in 2012. The mission traded sky coverage for depth, holding one view for years. That bias runs through its whole catalogue and through this planet's discovery.

:NOTE
Kepler-82 has 5 known planets. Systems like this are the ones where architecture can be studied instead of guessed at.
