Planets
The star HD 37605 hosts two confirmed giant planets. The first, planet b, was found in 2004, with planet c detected eight years later.
Neither world transits Earth; b’s maximum orbital tilt is 88.1%. Simulations show b’s orbit clears most material within half an astronomical unit, leaving only asteroids in low-eccentricity paths near its farthest point, at the 1:2 and 1:3 mean-motion resonances. Surveys have excluded any planet heavier than 0.7 Jupiter masses with an orbital period under one year, though worlds at 0.8 AU or farther remain possible.
