'''WASP-17'''是一個距離地球約 1000 光年，位於天蠍座的[[F-型主序星]]<ref>{{Cite web |url=http://arxiv.org/abs/0908.1553v1 |title=存档副本 |access-date=2011-09-18 |archive-date=2014-08-23 |archive-url=https://web.archive.org/web/20140823212811/http://arxiv.org/abs/0908.1553v1 }}</ref><ref>{{Cite web |url=http://www.space.com/scienceastronomy/090812-backward-planet.html |title=存档副本 |access-date=2011-09-18 |archive-date=2010-05-29 |archive-url=https://web.archive.org/web/20100529002318/http://www.space.com/scienceastronomy/090812-backward-planet.html }}</ref>。2009年發現該恆星有一顆行星環繞。該行星是首顆[[順行和逆行|逆行軌道]]（公轉方向和所屬恆星自轉方向相反）的行星。<br />

該恆星因為其環繞的[[太陽系外行星|行星]][[WASP-17b]]而相當特殊<ref>{{Cite web |url=http://news.bbc.co.uk/2/hi/science/nature/8197683.stm |title=BBC NEWS {{!}} Science & Environment {{!}} |access-date=2011-09-18 |archive-date=2010-06-24 |archive-url=https://web.archive.org/web/20100624060122/http://news.bbc.co.uk/2/hi/science/nature/8197683.stm }}</ref><ref>{{Cite web |url=http://news.yahoo.com/s/space/20090812/sc_space/newfoundplanetorbitsbackward |title=New-found Planet Orbits Backward |accessdate=2009-08-15 |archive-date=2009-08-15 |archive-url=https://web.archive.org/web/20090815040338/http://news.yahoo.com/s/space/20090812/sc_space/newfoundplanetorbitsbackward |dead-url=no }}</ref>，因為該行星的公轉方向和恆星自轉方向相反。而且該行星的體積是木星的兩倍，但質量只有木星的一半。<br />
<br />
該行星是由[[超廣角尋找行星|SuperWASP]]發現，並以該計畫名稱命名。<br />
