Question: The European Space Agency has put the HD 10927 at a distance of how many light-years away?
Context: HD 189733 b is an extrasolar planet approximately 63 light-years away from the Solar System in the constellation of Vulpecula.  The planet was discovered orbiting the star HD 189733 A on October 5, 2005, when astronomers in France observed the planet transiting across the face of the star.  With a mass 13% higher than that of Jupiter, HD 189733 b orbits its host star once every 2.2 days at an orbital speed of 152.5 km/s , making it a hot Jupiter with poor prospects for extraterrestrial life.  Being the closest transiting hot Jupiter to Earth, HD 189733 b is a subject for extensive atmospheric examination.  The atmosphere of HD 189733b has been extensively studied through high- and low-resolution instruments, both from ground and space.  HD 189733 b was the first extrasolar planet for which a thermal map was constructed, to be detected through polarimetry, to have its overall color determined (deep blue), to have a transit detected in X-ray spectrum and to have carbon dioxide detected in its atmosphere. HD 40979 is a yellow-white dwarf star about 108 light-years away in the constellation of Auriga.  The star is a member of a multiple system: it has a companion HD 40979B which shares its proper motion and is located at a projected distance of 6400 AU from the primary.  HD 40979B itself has a companion (designated HD 40979C) at a projected distance of 129 AU from star B, making the system a triple. The Austrian Space Agency, since 2005 officially Aeronautics and Space Agency (German: Agentur für Luft- und Raumfahrt) is an organization whose purpose is to coordinate Austrian space exploration-related activities, both national programs and European Space Agency related programs.  It was established in 1972 in Vienna.  In 1987, Austria became a member state of the European Space Agency. HD 109271 is a star in the constellation of Virgo.  With an apparent magnitude of 8.05, it cannot be seen with the naked eye.  Parallax measurements made by Gaia put the star at a distance of 185 light-years (56.7 parsecs) away. The Director General of the European Space Agency is the highest-ranked official of the European Space Agency (ESA), a space agency formed by the collaboration of prominent European nations. HD 20782 is a 7th magnitude G-type main sequence star about 117 light-years away from Earth, in the constellation of Fornax.  HD 20782 is a part of a wide binary system in which the other star is designated HD 20781, and both stars host planetary systems.  Indeed, this is the first known case of a binary star system where there are planetary systems around both the primary and the secondary stars in the system.  The companion star HD 20781 has a very large angular separation of 252 arcsec, corresponding to 9080 AU at the distance of HD 20782.  It is estimated to be 7.1 (± 4) billion years old, with a mass close to that of our Sun.  (Note that, despite the numbering, HD 20782 is the primary star of the system, and HD 20781 the secondary star.) The ESA Centre for Earth Observation (also known as the European Space Research Institute or ESRIN) is a research centre belonging to the European Space Agency (ESA), located in Frascati, Italy.  It is dedicated to research involving earth observation data taken from satellites, among other specialised activities.  The establishment currently hosts the European Space Agency's development team for the Vega launcher. Gaia is a space observatory of the European Space Agency (ESA) designed for astrometry: measuring the positions and distances of stars with unprecedented precision.  The mission aims to construct the largest and most precise 3D space catalog ever made, totalling approximately 1 billion astronomical objects, mainly stars but also planets, comets, asteroids and quasars among others. HD 156846 b is an extrasolar planet located approximately 160 light-years away in the constellation of Ophiuchus, orbiting the star HD 156846.  It has one of the most eccentric planetary orbits known.  The high eccentricity of this planet's orbit is probably attributable to the presence of a red dwarf companion star.  The average distance of the planet from HD 156846 is 0.99 AU, nearly identical to the distance of Earth from the Sun.  The distance ranges from 0.15 AU to 1.83 AU with a 360-day period.  It is also very massive with at least 10.45 Jupiter masses.  The mass is a lower limit because the inclination of the orbit is not known; if its inclination and hence true mass became known, it would probably be found to be a brown dwarf. Gomez's Hamburger, also known as IRAS 18059-3211, is believed to be a young star surrounded by a protoplanetary disk.  It was initially identified as a planetary nebula, and its distance was estimated to be approximately 6500 light-years away from Earth.  However, recent results suggest that this object is a young star surrounded by a protoplanetary disk, at a distance of about 900 light-years away.
Answer: 185 light-years
