:INFO
Terrestrial around Kepler-131
It is 0.84 times Earth's radius, closest in size to Venus, and 8.2 times Earth's mass, at 77.70 g/cm3, denser than Earth. A year there lasts 25.52 days. The host star Kepler-131 runs at 5685 K with 1.02 times the Sun's mass.

:COUNTER
77.7 g/cm3: denser than iron at Earth surface pressure

:CHECKLIST
What the archive holds on this planet
[ ] A size. Yes.
[ ] A mass. Yes.
[ ] A density, the one clue to composition. Yes.
[ ] How far out it orbits. No.
[ ] An observed temperature. No.
[ ] An eccentricity, so the orbit shape is known. No.

:PATH
What a crossing measures
The fraction of starlight blocked sets the radius against the star's.

: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
Found by Kepler in 2014. Kepler watched a single field continuously, so it found the planets that come round often. A world with a long year simply never repeated within the mission.

:NOTE
Kepler-131 has 2 known planets. Systems like this are the ones where architecture can be studied instead of guessed at.
