Colder than Mars
So I crunched the numbers and this planet gets less irradiance than Mars does at aphelion, Mars ... 43.07% / 52.40% / 36.03% 438b ... 33.70% / 29.65% / 26.48%  where 100% is Earth's Solar Constant. And using 0.12 ecc. Zero would just be 29.65% therefore something doesn't add up about this planet if they're saying it's -40 °C. I doubt that. I have to assume this planet is closer to Mars' winter low of -143°C. I'm using percent, while the article uses percentile. The article quotes 0.66 insolation, while the reference source says 0.66 (+0.23 / −0.41) S⊕, which is more accurate and more truthful. Yet another Notable Hall of Fame Kepler planet that is doubtful is really habitable. Someone should be double checking that list for accuracy, they seem false & deceptive to me. 24.79.36.94 (talk) 10:28, 6 February 2015 (UTC)

Incorrect Planetbox usage
The image in the infobox should not be used as it does not follow the usage guide for the template:

This template is part of a group of templates that are used to display information about a specific extrasolar planet. Images of published planetary properties are preferred where available, especially when they are available from cited publications. ''' Artist's conception, regardless of the source, should be avoided. ''' Examples of acceptable images include * direct images, such as one used for GJ 758 b, in the rare cases where these are available; * output of a model that is integral to a cited paper, such as the image used in HD 80606 b; * user-generated images that clearly illustrate published properties, such as the size comparisons currently used in GJ 1214 b or Gliese 436 b.

My edits followed these guidelines but were revered by User:MarioProtIV.

A useful radius comparison to Earth should be a plain ball similar to other articles.

Super Earth
NASA has Kepler-442b logged as a super Earth as its mass is 2.36 Earths. Why does the opening say its a near-Earth-sized exoplanet. This not near-Earth-sized, need use NASA's Exoplanet Catalog. Will change if no reply. See. The star page, Kepler-442, correctly calls it a Super Earth. Telecine Guy (talk) 19:26, 19 February 2024 (UTC)
