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":"toi-1694-c","name":"TOI-1694 c","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":406.6517717372357,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":97.7487104,"dec_deg":66.3605956,"epoch_ra_deg":98.431944,"epoch_dec_deg":66.341829,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-1694","semi_major_axis_km":145708326.06179997,"periapsis_km":null,"mass_kg":1.8905321013457495e+27,"mass_msun":0.000950776,"constellation":"Camelopardalis","discovered":"2023","featured":false,"url":"https://spacecatalog.org/object/toi-1694-c","radius_km":88017.78000000001,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-1694","host_v_mag":11.446,"eccentricity":0.111,"uncertainties":{"mass_kg":[4.9351239581730405e+25,5.124936419940362e+25],"distance_ly":[1.9047532458657814,1.924322628528786],"eccentricity":[0.025,0.025],"host_mass_solar":[0.032,0.039],"host_radius_solar":[0.022,0.023],"host_temperature_k":[65,65],"semi_major_axis_km":[4338338.2502999995,4188740.3795999996],"orbital_period_days":[2.13,2.08],"argument_of_periastron_deg":[9.66,8.92]},"host_mass_solar":0.828,"stars_in_system":1,"discovery_method":"Radial Velocity","host_radius_solar":0.812,"planets_in_system":2,"discovery_facility":"W.
