HD 195019 is a Sun-like star in the constellation Delphinus around which has been found a three-Jupiter-mass exoplanet of the epistellar
Jovian type.1 Spectroscopic measurements of the host suggest
that it is has a "quiet" chromosphere (an important factor in its suitability to support nearby life) and a metal-content
somewhat greater than that of the Sun.
