We report the discovery of the transiting giant planet WASP-17b, the least-dense planet currently known. It is 1.6 Saturn masses but 1.5-2 Jupiter radii, giving a density of 6-14 per cent that of Jupiter. WASP-17b is in a 3.7-day...

At least one extrasolar planet, WASP-17b, has been found to orbit in the opposite direction to its star's rotation. حداقل یک سیاره فراخورشیدی شناختهشده به نام وسپ-۱۷بی...
By combining\nthe resulting light curves with existing transit light curves and radial\nvelocity measurements in a simultaneous analysis, we find the radius of\nWASP-17b to be 2.0 Rjup, which is 0.2 Rjup larger than any other known planet\nand 0.7 Rjup larger than predicted by the standard...
planets and satellites: individual: WASP-17bstars: individual: WASP-17planetary systemsWe present the detection of sodium absorption in the atmosphere of the extrasolar planet WASP-17b, an inflated ‘hot Jupiter’ in a tight orbit around an F6 dwarf. In-transit observations of WASP-17 made with...
