The semi-major axis of the planet to the star is 3.38 AU while the semi-minor axis is 2.59 AU . This planet passes through the star's habitable zone at periastron ( 1.21 AU ) while at apastron, it passes to beyond Jupiter-Sun distance ( 5.54 AU ).

In a simulation, HD 37605 b's orbit " sweeps clean " most test particles within 0.5 AU; leaving only asteroids " in low-eccentricity orbits near the known planet s apastron distance, near the 1 : 2 mean-motion resonance " with oscillating eccentricity up to 0.06, and also at 1 : 3 with oscillating eccentricity up to 0.4.
