HIP 14810 is a planetary system 170 light-years away in the constellation Aries. With a magnitude of 8.5, it is visible with binoculars but not with the naked eye. The star is similar to the Sun, but older (about 8 billion year old) and nearly twice as metal-rich. The three known planets of the system, named HIP 14810 b, c and d, are all giant worlds and are located at respectively 0.07, 0.54 and 1.89 times the Sun-Earth distance of their star, hence estimated equilibrium temperatures of about 700 °C, 50 °C and -100 °C. Given their masses, they are therefore respectively a hot super-Jupiter, a temperate Jupiter and a cold Jupiter.
