Orbital period
editCiting the article: With an orbital period of 40 days, it is located 210 light years away, orbiting its parent star Kepler-37 in the constellation Lyra. Its size is slightly smaller than Venus, and has an orbital period of 21 days. So what is the orbital period? 40 days or 21 days? Jahoe (talk) 18:07, 25 February 2013 (UTC)

- This is not for the article nor is it original research.
It's a pretty simple formula to calculate irradiance from Star Temperature & Radius, and the semi-major axis of the planet.
| KEPLER 37 | b | c | d | Earth | |
| Star Temperature | 5417 | ||||
| Star Radius | 0.77 | ||||
| Semimajor axis (AU) | 0.1003 | 0.1368 | 0.2076 | ||
| Irradiance (W/m²) |
62197.08 | 33434.87 | 14518.35 | 1366.05 [1]
| |
| Percent of Earth's | 4553.1% | 2447.6% | 1062.8% | 100% | |
| Known temperature, Pre-GHG | 700 K | 255 K | |||
| 247°C | -18°C |
I'm not suggesting these figures be put in the article, I would just rather users were not ignorant of how HOT these planets are, so they aren't inserting silly ideas about habitability where they don't belong. Hopfully someone will find references for any published missing temperatures. thanks. 24.79.38.15 (talk) 11:00, 17 April 2013 (UTC)
