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":"hip-14810-d","name":"HIP 14810 d","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":164.64373947141206,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":47.809275,"dec_deg":21.0971302,"epoch_ra_deg":48.195874,"epoch_dec_deg":21.198899,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"HIP 14810","semi_major_axis_km":290219869.158,"periapsis_km":null,"mass_kg":1.119899126917879e+27,"mass_msun":0.000563213,"constellation":"Aries","discovered":"2009","featured":false,"url":"https://spacecatalog.org/object/hip-14810-d","radius_km":89931.21,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"HIP 14810","host_v_mag":8.520001,"eccentricity":0.185,"uncertainties":{"mass_kg":[1.8981341134201343e+26,1.8981341134201343e+26],"distance_ly":[0.3754059907519717,0.37703677264055535],"eccentricity":[0.035,0.035],"host_mass_solar":[0.19,0.19],"host_radius_solar":[0.08,0.08],"semi_major_axis_km":[19447723.191,19447723.191],"orbital_period_days":[6.9,6.9],"argument_of_periastron_deg":[12,12]},"host_mass_solar":1.01,"stars_in_system":1,"discovery_method":"Radial Velocity","host_radius_solar":1.07,"planets_in_system":3,"discovery_facility":"W.
