English: Plot of the orbit of HD 85512 b compared to the star's habitable zone

Orbit data taken from Pepe et al. (2011), arXiv:1108.3447v1 [astro-ph.EP] "The HARPS search for Earth-like planets in the habitable zone: I – Very low-mass planets around HD20794, HD85512 and HD192310"

The configuration is given in Table 5. Uncertainties in the quantities are not depicted.

The habitable zone limits are computed using the formulae given in: Underwood et al. (2003), International Journal of Astrobiology vol. 2 (4), pp. 289–299 "The evolution of habitable zones during stellar lifetimes and its implications on the search for extraterrestrial life"

The habitable zone is colour-coded as follows:

Red: Recent Venus (inner) – Runaway greenhouse (outer)

Yellow: Runaway greenhouse (inner) – Water loss (outer)

Green: Water loss (inner) – First CO₂ condensation (outer)

Cyan: First CO₂ condensation (inner) – Maximum greenhouse (outer)

Blue: Maximum greenhouse (inner) – Early Mars (outer)

Using this definition of the habitable zone, the most conservative habitable zone is the green region, the inner boundary corresponding to the start of water loss and the outer limit corresponding to the first condensation of carbon dioxide in the atmosphere.
