Super-earth around Kepler-85
It is 1.78 times Earth's radius, closest in size to Earth, and 1.8 times Earth's mass, at 1.82 g/cm3, less dense than Earth. A year there lasts 8.30 days. The host star Kepler-85 runs at 5505 K with 0.93 times the Sun's mass.

:CHECKLIST
The state of the record for this planet
[ ] A measured radius. Yes.
[ ] A mass. Yes.
[ ] A density, the one clue to composition. Yes.
[ ] A semi-major axis. No.
[ ] A measured temperature rather than a derived one. No.
[ ] An eccentricity, so the orbit shape is known. Yes.

What you get from the shadow
How deep the star dims fixes the planet's size relative to it.

:NOTE
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.

:NOTE
Kepler-85 has 4 known planets. A crowded system is worth more than the sum of its planets: the timing of each transit constrains the others.

:NOTE
Found by Kepler in 2012. Kepler stared at one patch of sky for four years, which is why so many of its planets have short periods: a planet only counts once you have seen it cross several times.
