                Description The planetary system around HD 219134 was discovered independently by teams using HARPS-N and APF, who announced four-planet and six-planet solutions respectively. Spitzer observations allowed the discoverers to detect the transit of the innermost planet in front of the star making HD 219134 b the nearest known transiting planet to date. The planetary system around HD 219134 was discovered independently by teams using HARPS-N and APF, who announced four-planet and six-planet solutions respectively. Transits of the second planet were detected in 2017. The planetary system around HD 219134 was discovered independently by teams using HARPS-N and APF, who announced four-planet and six-planet solutions respectively. HD 219134 with its four low-mass planets is the first result of the Rocky Planet Search program with HARPS-N on the Telescopio Nazionale Galileo in La Palma. This planet was designated HD 219134 d in the HARPS-N announcement. The planetary system around HD 219134 was discovered independently by teams using HARPS-N and APF, who announced four-planet and six-planet solutions respectively. The planet candidate HD 219134 e was discovered by Motalebi et al. (2015). It was subsequently shown to be the same candidate as HD 219134 h from Vogt et al. (2015), and the latter name is now used for this planet. The planetary system around HD 219134 was discovered independently by teams using HARPS-N and APF, who announced four-planet and six-planet solutions respectively. In the HARPS-N solution, this planet was designated HD 219134 e and was assigned a shorter-period, more eccentric orbit.

                Planet sizes

                The following plot shows the approximate sizes of the planets in this system The Solar System planets are shown as a comparison. Note that unless the radius has been determined through a transit observation, this is only an approximation (see Lissauer et al. 2011b).

                Habitable zone

                The following plot shows the approximate location of the planets in this system with respect to the habitable zone (green) and the size of the star (red). This is only an estimate, using the star's spectral type and mass. Note that if no green band is shown in the plot, then the planet's orbit is far outside the habitable zone. The equations of Selsis, Kasting et al are used to draw the inner and outer boundaries.
