| '''HR 3803''' or '''N Velorum''' (N Vel) is a 3rd-[[Apparent magnitude|magnitude]] [[star]] on the border between the southern [[constellation]]s [[Carina (constellation)|Carina]] and [[Vela (constellation)|Vela]]. Based upon [[parallax]] measurements, it is approximately {{Convert|239|ly|pc|abbr=off|lk=on}} from [[Earth]]. It is an orange-hued [[stellar classification|K-type]] [[giant star]] and has twice the mass of the Sun.<ref name=aaa352_217/> The measured [[angular diameter]] of this star, after correction for [[limb darkening]], is {{nowrap|7.13 ± 0.08 [[milliarcsecond|mas]]}}.<ref name=aaa431_773/> At the estimated distance of Eta Draconis,<ref name=aaa474_2_653/> this yields a physical size of about 29 times the [[Solar radius|radius of the Sun]].<ref name=lang2006/>
| |
| | |
| In 1752, French astronomer [[Nicolas Louis de Lacaille]] divided the former constellation [[Argo Navis]] into three separate constellations, and then referenced its stars by extending [[Bayer designation|Bayer's system of star nomenclature]];<ref>http://homepage.mac.com/andjames/Page206.htm</ref> this star was given the designation ''N Velorum''. In 1871 [[Benjamin Apthorp Gould]] discovered this star to be [[variable star|variable]], but this occurred prior to the standardization of variable star nomenclature by German astronomer [[Friedrich Wilhelm Argelander]] during the nineteenth century, so it does not fall into the standard range of variable star designations.<ref name=jaavso16_2_65/>
| |
| | |
| The star should not be confused with [[HD 74272|n Velorum]].

Hi there. My title is Sophia Meagher even though it is not the name on my birth certification. My working day occupation is an invoicing officer but I've already utilized for another one. For many years she's been residing in Kentucky but her spouse wants them to transfer. What I adore doing is soccer but I don't have the time recently.
