We report the discovery and initial characterization of Qatar-2b , a hot Jupiter transiting a V = 13.3 mag K dwarf in a circular orbit with a short period , P _ { b } = 1.34 days .
The mass and radius of Qatar-2b are M _ { P } = 2.49 M _ { J } and R _ { P } = 1.14 R _ { J } , respectively .
Radial-velocity monitoring of Qatar-2 over a span of 153 days revealed the presence of a second companion in an outer orbit .
The Systemic Console yielded plausible orbits for the outer companion , with periods on the order of a year and a companion mass of at least several M _ { J } .
Thus Qatar-2 joins the short but growing list of systems with a transiting hot Jupiter and an outer companion with a much longer period .
This system architecture is in sharp contrast to that found by Kepler for multi-transiting systems , which are dominated by objects smaller than Neptune , usually with tightly spaced orbits that must be nearly coplanar .
