'''WASP-7'''，或稱為'''HD 197286'''，是一顆距離地球約456光年的[[恆星光譜|光譜類型]] F 型恆星，位於[[顯微鏡座]]。該恆星的半徑比太陽稍大，質量是太陽的1.28倍，光度和溫度也稍高於太陽。它的視星等為9等，必須以小型望遠鏡觀測<ref name="SIMBAD">{{cite web<br />

[[超廣角尋找行星|SuperWASP]] 計畫於2008年宣布在該恆星旁發現系外行星 [[WASP-7b]]。該行星應屬於[[熱木星]]，質量和體積都比木星稍小，且距離母恆星相當近，因此溫度夠高，足以發出一定熱量<ref name="disc">{{ cite journal<br />
