:INFO
Gas giant around Kepler-297
It is 2.91 times Jupiter's radius, closest in size to Jupiter. A year there lasts 150.02 days, on an orbit 1.4 times Mercury's distance from the Sun. Its equilibrium temperature is 325 K, hotter than any desert. The host star Kepler-297 runs at 5618 K with 0.85 times the Sun's mass.

What the dip tells you
How deep the star dims fixes the planet's size relative to it.

:CHECKLIST
The habitability checklist, honestly scored
[ ] Orbits inside the computed habitable zone. No.
[ ] A measured mass, not just a radius. No.
[ ] A measured temperature rather than one derived from the star. Yes.
[ ] Any detection of an atmosphere. Not recorded in the archive.

:NOTE
Kepler-297 has 3 known planets. A crowded system is worth more than the sum of its planets: the timing of each transit constrains the others.

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

:NOTE
Found by Kepler in 2023. 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.
