We report the discovery by the Gemini NICI Planet-Finding Campaign of two low-mass companions to the young A0V star HD 1160 at projected separations of 81 \pm 5 AU ( HD 1160 B ) and 533 \pm 25 AU ( HD 1160 C ) . VLT images of the system taken over a decade for the purpose of using HD 1160 A as a photometric calibrator confirm that both companions are physically associated . By comparing the system to members of young moving groups and open clusters with well-established ages , we estimate an age of 50 ^ { +50 } _ { -40 } Myr for HD 1160 ABC . While the UVW motion of the system does not match any known moving group , the small magnitude of the space velocity is consistent with youth . Near-IR spectroscopy shows HD 1160 C to be an M3.5 \pm 0.5 star with an estimated mass of 0.22 ^ { +0.03 } _ { -0.04 } M _ { \odot } , while NIR photometry of HD 1160 B suggests a brown dwarf with a mass of 33 ^ { +12 } _ { -9 } M _ { Jup } . The very small mass ratio ( 0.014 ) between the A and B components of the system is rare for A star binaries , and would represent a planetary-mass companion were HD 1160 A to be slightly less massive than the Sun .
