Super-earth around Kepler-441
It is 1.64 times Earth's radius, closest in size to Earth. A year there lasts 207.25 days, on an orbit 1.7 times Mercury's distance from the Sun. Its equilibrium temperature is 177 K (derived from the star rather than measured), colder than anywhere on Earth. The host star Kepler-441 runs at 4340 K with 0.57 times the Sun's mass.

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

:CHECKLIST
The habitability checklist, honestly scored
[ ] Within the zone where liquid water could persist. No.
[ ] A measured mass, not just a radius. No.
[ ] A measured temperature rather than one derived from the star. No.
[ ] Any detection of an atmosphere. Not recorded in the archive.

:NOTE
The archive lists no measured equilibrium temperature for this planet. The 177 K quoted here is derived from the star's output and the orbital distance, assuming a third of the light is reflected. It is an estimate from two numbers, not an observation.

:NOTE
Found by watching its star dim as it crossed in front. That measures size and not weight, which is why there is a radius here and no mass.

:NOTE
Found by Kepler in 2015. Kepler's method needed repetition, not brightness. It could find small planets around faint stars, provided they came round quickly enough to be seen twice.
