Query: A Potential Super-Venus in the Kepler-69 System   Transiting planets have greatly expanded and diversified the exoplanet field.
These planets provide greater access to characterization of exoplanet
atmospheres and structure. The Kepler mission has been particularly successful
in expanding the exoplanet inventory, even to planets smaller than the Earth.
The orbital period sensitivity of the Kepler data is now extending into the
Habitable Zones of their host stars, and several planets larger than the Earth
have been found to lie therein. Here we examine one such proposed planet,
Kepler-69c. We provide new orbital parameters for this planet and an in-depth
analysis of the Habitable Zone. We find that, even under optimistic conditions,
this 1.7 R$_\oplus$ planet is unlikely to be within the Habitable Zone of
Kepler-69. Furthermore, the planet receives an incident flux of 1.91 times the
solar constant, which is similar to that received by Venus. We thus suggest
that this planet is likely a super-Venus rather than a super-Earth in terms of
atmospheric properties and habitability, and we propose follow-up observations
to disentangle the ambiguity.
