This planet was discovered on October 26, 2008 by Moutou et al. using the HARPS spectrograph on ESO's 3.6 meter telescope installed at La Silla Observatory in Atacama Desert, Chile.
This would also likely apply to a potentially habitable hypothetical moon orbiting the gas giant exoplanet (see below).
The exoplanet, with a mass of 2.73 MJ, is too massive to be rocky, and because of this the planet itself is not expected to habitable.
However, based on a probable 10−4 fraction of the planet mass as a satellite,[5] it may have a large enough moon with a sufficient atmosphere and pressure, and liquid water at its surface, potentially making it habitable.
In the case of HD 153950, the star was observed using telescopes at the La Silla Observatory in Chile.
