Super-earth around KOI-351
It is 1.32 times Earth's radius, closest in size to Earth. A year there lasts 14.45 days. Its equilibrium temperature is 709 K, hot enough to melt lead. The host star KOI-351 runs at 6015 K with 1.12 times the Sun's mass.

What you get from the shadow
The depth of the dip is the ratio of the two discs, so the radius follows.

:CHECKLIST
Known and unknown, as the archive has it
[ ] A size. Yes.
[ ] A mass. No.
[ ] A density, which decides rock or gas. No.
[ ] How far out it orbits. No.
[ ] A temperature someone observed rather than calculated. Yes.
[ ] An eccentricity, so we know if the orbit is a circle. No.

:NOTE
Everything known here comes from how much light went missing. That fixes the size and leaves the mass entirely open.

:NOTE
KOI-351 has 8 known planets. Multi-planet systems are where orbital dynamics can be measured rather than assumed.

:NOTE
Found by Kepler in 2017. 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.
