Is Ùranas no Urànus (o Οὐρανός Sheann-Ghreugais tro Uranus Laideann) an t-seachdamh planaid on ghrian. Tha an treas rèideas planaideach as motha agus an ceathramh tomad planaideach as motha aige san rian-grèine againn. Tha stuthan Ùranais coltach ri stuthan Neaptuin, ach tha na stuthan ceimigeach aca diofraichte on fheadhainn aig na famhairean gasa nas motha, siud am Bliogh agus Satarn. 'S ann air an adhbhar seo gun cuir na h-eòlaichean "fuamhairean deighe" air Ùranas agus Neaptun gus an diofar eatorra is na fuamhairean gas a nochdadh. Tha àile Ùranais coltach ri feadhainn a' Bhliogh agus Satairn on a tha a' mhòrchuid dhe 'na hàidhdreaidean is hilium ach tha barrachd "deighean" aige mar uisge, amòinia agus methan cho math ri lorgan hàidhdrea-charbonan eile.[10] 'S e an t-àile planaideach as fhuaire sa rian-ghrèine a th' ann agus is 49 K (−224.2 °C) an teothachd as lugh agus tha breathan neòil iom-fhillte aige. Thathar dhen bheachd gu bheil an t-uisge pailt sna neòil as ìsle agus methan sna neòil as àirde.[10] Tha a' mhòrchuid dhe mheadhan Ùranais 'na dheighean is clach.[9]

Chan fhaicear Ùranas leis an t-siùil lom ach gu fann. Chaidh a lorg le William Herschel. 'S e planaid uaine/glas a tha ann.
