cds-question@unistra.frgravitational-lensingvariable-starsmilky-way-galaxyapparent-magnitudeMost known extrasolar planets (exoplanets) have been discovered using the radial velocity or transit methods. Both are biased towards planets that are relatively close to their parent stars, and studies find that around 17-30% of solar-like stars host a planet. Gravitational microlensing on the other hand, probes planets that are further away from their stars. Recently, a population of planets that are unbound or very far from their stars was discovered by microlensing. These planets are at least as numerous as the stars in the Milky Way. Here we report a statistical analysis of microlensing data (gathered in 2002-07) that reveals the fraction of bound planets 0.5-10AU (Sun-Earth distance) from their stars. We find that of stars host Jupiter-mass planets (0.3-10M_J_, where M_J_=318M_{earth}_ and M_{earth}_ is Earth's mass). Cool Neptunes (10-30M_{earth}_) and super-Earths (5-10M_{earth}_) are even more common: their respective abundances per star are 52^+22^_-29_% and 62^+35^_-37_%. We conclude that stars are orbited by planets as a rule, rather than the exception.2012Natur.481..167Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/Nat/481.167CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AcA/50/1 : OGLE microlensing events in Galactic Bulge (Udalski+, 2000)J/AcA/51/175 : OGLE-II DIA microlensing events (Wozniak+, 2001)J/MNRAS/343/1131 : 1998-2000 OGLE events microlensing limits (Tsapras+, 2003)J/ApJ/631/906 : MACHO Galactic Bulge microlensing events (Thomas+, 2005)J/ApJ/636/240 : OGLE II microlensing parameters (Sumi+, 2006)J/A+A/454/185 : EROS-2 microlensing parameters (Hamadache+, 2006)J/ApJ/711/L48 : 2008 OGLE Bulge microlensing alerts (Cohen+, 2010)J/A+A/512/A41 : Abundances of microlensed stars in the Bulge (Bensby+, 2010)J/A+A/533/A134 : Abundances of microlensed stars in the Bulge (Bensby+, 2011)J/A+A/549/A147 : Abundances of microlensed stars in the Bulge (Bensby+, 2013)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/Nat/481.167https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/Nat/481.167http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/Nat/481.167https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/Nat/481.167https://vizier.iucaa.in/viz-bin/votable?-source=J/other/Nat/481.167http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/Nat/481.167GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/other/Nat/481.167/tables1 (List of events followed by PLANET from 2002-2007)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/Nat/481.167/tables1?https://vizier.iucaa.in/viz-bin/conesearch/J/other/Nat/481.167/tables1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/Nat/481.167/tables1?GETtext/xml+votable180.050000true267.8173333-30.20872220.0055555555555555565/7179 7181 7182 7183 7194 7205 7216 7217 6/28707 28709 28710 28711 28715 28723 28746 28780 28782 28783 28804 28817 28819 28873 28876 28880 28883 28905https://cdsarc.cds.unistra.fr/viz-bin/moc/J/other/Nat/481.167?format=asciiOpticaldefaultJ/other/Nat/481.167/tables1List of events followed by PLANET from 2002-2007recnoRecord number assigned by the VizieR team.
