Also known as XO-5b, TOI-5373.01, TIC 9155187b

XO-5b "Makropulos" is an extrasolar planet approximately 910 light years away in the constellation of Lynx. This planet was found by the transit method using the XO Telescope and announced in May 2008. It was also independently discovered by the HATNet Project. The planet has a mass and radius just slightly larger than that of Jupiter. This planet orbits very close to the G-type parent star, as it is typical for transiting planets, classing this as Hot Jupiter. It takes only 4.188 days (or 100.5 hours) to orbit at an orbital distance of 0.0488 AU).

The planet XO-5b is named Makropulos. The name was selected in the NameExoWorlds campaign by the Czech Republic, during the 100th anniversary of the IAU. Makropulos is the name from Karel Čapek's play Věc Makropulos (The Makropulos Affair).
