The catalogued J2000 position is carried along the great circle the object's own published motion puts it on, at a constant velocity, and the result is referred to the true equator and equinox of this instant. Those are separate things: the motion moves the object, and the rotation turns the grid under it by about fifty arcseconds a year, with nutation adding up to another seventeen.","excluded":"Parallax, the radial-velocity perspective term, aberration and refraction; each is below the accuracy of the catalogued positions themselves. An object with no published proper motion comes back where the catalogue has it rather than at a fabricated zero, and says so with a null pm_ra_mas_yr. A body with no fixed position is not propagated at all — its place comes from an ephemeris, which is what /api/v1/visible answers with."},"slug":"hd-126614-b","name":"HD 126614 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":238.4075920122085,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":216.7005171,"dec_deg":-5.1784093,"epoch_ra_deg":217.05289,"epoch_dec_deg":-5.299474,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"HD 126614","semi_major_axis_km":336445611.2043,"periapsis_km":null,"mass_kg":6.434642392996117e+26,"mass_msun":0.000323607,"constellation":"Virgo","discovered":"2009","featured":false,"url":"https://spacecatalog.org/object/hd-126614-b","radius_km":81001.87,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"HD 126614","host_v_mag":8.81,"eccentricity":0.548,"uncertainties":{"mass_kg":[3.6064367377461185e+25,3.8721741836231535e+26],"distance_ly":[0.794516936117987,0.8000615945391716],"eccentricity":[0.062,0.063],"host_mass_solar":[0.117,0.117],"inclination_deg":[37.849,35.34],"host_radius_solar":[0.031487,0.031487],"host_temperature_k":[23,23],"semi_major_axis_km":[14361395.587199999,13164612.621599998],"orbital_period_days":[6.1876,5.95652],"argument_of_periastron_deg":[12.242,9.91]},"host_mass_solar":0.96,"inclination_deg":97.477,"stars_in_system":3,"discovery_method":"Radial Velocity","host_radius_solar":1.369794,"planets_in_system":1,"discovery_facility":"W.
