[en] We report the discovery and characterisation of WASP-180Ab, a hot Jupiter confirmed by the detection of its Doppler shadow and by measuring its mass using radial velocities. We find the 0.9 ± 0.1 M[SUB]Jup[/SUB], 1.24 ± 0.04 R[SUB]Jup[/SUB] planet to be in a misaligned, retrograde orbit around an F7 star with T[SUB]eff[/SUB] = 6500 K and a moderate rotation speed of vsin i[SUB]⋆[/SUB] = 19.9 km s[SUP]-1[/SUP]. The host star is the primary of a V = 10.7 binary, where a secondary separated by ̃5″ (̃1200 AU) contributes ̃ 30% of the light. WASP-180Ab therefore adds to a small sample of transiting hot Jupiters known in binary systems. A 4.6-day modulation seen in the WASP data is likely to be the rotational modulation of the companion star, WASP-180B.
