The discovery was confirmed in 2020 when scientists observed the Proxima system with a new instrument on ESO\u2019s<a href=\"https:\/\/www.eso.org\/public\/teles-instr\/paranal-observatory\/vlt\/\"> VLT<\/a> that had greater precision, the Echelle SPectrograph for Rocky Exoplanets and Stable Spectroscopic Observations (<a href=\"https:\/\/www.eso.org\/public\/teles-instr\/paranal-observatory\/vlt\/vlt-instr\/espresso\/\">ESPRESSO<\/a>). It was during these more recent VLT observations that astronomers spotted the first hints of a signal corresponding to an object with a five-day orbit. As the signal was so weak, the team had to conduct follow-up observations with ESPRESSO to confirm that it was due to a planet, and not simply a result of changes in the star itself.<\/p>\n<p dir=\"ltr\" style=\"padding-left: 40px;\">\u201c<em>After obtaining new observations, we were able to confirm this signal as a new planet candidate,<\/em>\u201d Faria says. \u201c<em>I was excited by the challenge of detecting such a small signal and, by doing so, discovering an exoplanet so close to Earth.<\/em>\u201d<\/p>\n<p dir=\"ltr\">At just a quarter of the mass of Earth, Proxima d is the lightest exoplanet ever measured using the radial velocity technique,<a href=\"https:\/\/www.eso.org\/public\/news\/eso2112\/\"> surpassing a planet recently discovered in the L 98-59 planetary system<\/a>. The technique works by picking up tiny wobbles in the motion of a star created by an orbiting planet\u2019s gravitational pull. The effect of Proxima d\u2019s gravity is so small that it only causes Proxima Centauri to move back and forth at around 40 centimetres per second (1.44 kilometres per hour).<\/p>\n<p dir=\"ltr\" style=\"padding-left: 40px;\">\u201c<em>This achievement is extremely important,<\/em>\u201d says Pedro Figueira, ESPRESSO instrument scientist at ESO in Chile. \u201c<em>It shows that the radial velocity technique has the potential to unveil a population of light planets, like our own, that are expected to be the most abundant in our galaxy and that can potentially host life as we know it.<\/em>\u201d<\/p>\n<p dir=\"ltr\" style=\"padding-left: 40px;\">\u201c<em>This result clearly shows what ESPRESSO is capable of and makes me wonder about what it will be able to find in the future<\/em>,\u201d Faria adds.<\/p>\n<p dir=\"ltr\">ESPRESSO\u2019s search for other worlds will be complemented by ESO\u2019s Extremely Large Telescope (<a href=\"https:\/\/elt.eso.org\/\">ELT<\/a>), currently under construction in the Atacama Desert, which will be crucial to discovering and studying many more planets around nearby stars.<\/p>\n<p><strong>Links<\/strong><\/p>\n<ul>\n<li><a href=\"https:\/\/www.eso.org\/public\/archives\/releases\/sciencepapers\/eso2202\/eso2202a.pdf\">Research paper<\/a><\/li>\n<li dir=\"ltr\"><a href=\"http:\/\/www.eso.org\/public\/images\/archive\/category\/paranal\/\">Photos of the VLT<\/a><\/li>\n<li dir=\"ltr\"><a href=\"https:\/\/elt.eso.org\">Find out more about ESO&#8217;s Extremely Large Telescope<\/a><\/li>\n<li dir=\"ltr\"><a href=\"https:\/\/www.eso.org\/public\/outreach\/pressmedia\/#epodpress_form\">For journalists: subscribe to receive our releases under embargo in your language<\/a><\/li>\n<li dir=\"ltr\"><a href=\"http:\/\/www.eso.org\/sci\/publications\/announcements\/sciann17463.html\">For scientists: got a story?
