HD 40307 g is an exoplanet candidate suspected to be orbiting in the habitable zone of HD 40307. It is located 42 light-years away in the direction of the southern constellation Pictor.

Oct 25, 2024 · HD 40307 g is a Neptune-like exoplanet that orbits a K-type star. Its mass is 7.1 Earths, it takes 197.8 days to complete one orbit of its star, and is 0.6 AU from its star. Its discovery was announced in 2013.

HD 40307 is an orange (K-type) main-sequence star located approximately 42 light-years away in the constellation of Pictor (the Easel), taking its primary name from its Henry Draper Catalogue designation. It is calculated to be slightly less massive than the Sun.

Nov 8, 2012 · Now, a team of researchers poring over data from ESO’s HARPS planet-hunting instrument are suggesting that there are likely at least six super-Earth exoplanets orbiting HD 40307 — with one of...

Nov 8, 2012 · HD 40307 is a quiet K-type dwarf star, a bit smaller and cooler than the Sun, which appears in Earth's southern skies to reside about eight degrees SSE of Canopus, the brightest star in the...

Nov 8, 2012 · The super-Earth exoplanet HD 40307g, 44 light-years away, is seven times the Earth's mass and may have liquid water on its surface, making it a candidate to support alien life.

Nov 8, 2012 · The outermost planet of the six is the one to watch. HD 40307’s habitable zone lies between 0.43 and 0.85 AU. With an orbital semi-major axis of 0.60 AU, candidate planet HD 40307 g is in the sweet spot, receiving about 62 percent of …

Oct 10, 2024 · HD 40307 g is a Confirmed extrasolar planet (exoplanet) that orbits the star HD 40307 in the constellation of Pictor

The planet candidate HD 40307 g would be a sub-Neptune planet located in the habitable zone of the star. Follow-up analysis of the HARPS data for the system did not confirm this planet candidate. The spectral window function has peaks near this period, and there is also the possibility that it is an alias of the star's activity cycle.

HD 40307 g is an exoplanet orbiting the star HD 40307, located about 42.4 light-years (13.0 pc) away from Solar System. Its discovery was publicly announced on 2012. The host star HD 40307 has apparent magnitude of 7.2, with absolute magnitude of 6.6.
