摘要
WX Dra (KIC 10581918) is listed as an eclipsing binary whose light curve shows slowly evolving starspot structures that also affect the O-C timings. Our long-term eclipse timing measurements indicate period variations probably caused by a third body orbiting the eclipsing pair with a period of about 15 years.
