cds-question@unistra.frmultiple-starssolar-system-planetsradial-velocityWe know now from radial velocity surveys and transit space missions that planets only a few times more massive than our Earth are frequent around solar-type stars. Fundamental questions about their formation history, physical properties, internal structure, and atmosphere composition are, however, still to be solved. We present here the detection of a system of four low-mass planets around the bright (V=5.5) and close-by (6.5pc) star HD 219134. This is the first result of the Rocky Planet Search programme with HARPS-N on the Telescopio Nazionale Galileo in La Palma. The inner planet orbits the star in 3.0935+/-0.0003-days, on a quasi-circular orbit with a semi-major axis of 0.0382+/-0.0003AU. Spitzer observations allowed us to detect the transit of the planet in front of the star making HD 219134 b the nearest known transiting planet to date.2015A&A...584A..72Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/584/A72CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/584/A72https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/584/A72http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/584/A72https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/584/A72https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/584/A72http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/584/A72GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/584/A72/table6List of undetected sources.
