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-1752-b","name":"TOI-1752 b","class":"super_earth","category":"exoplanet","object_type":"Super-Earth","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":336.00956188756624,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":253.4614861,"dec_deg":60.7096197,"epoch_ra_deg":253.551468,"epoch_dec_deg":60.664936,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-1752","semi_major_axis_km":2429469.420168,"periapsis_km":null,"mass_kg":2.0962309215947738e+25,"mass_msun":0.0000105422,"constellation":"Draco","discovered":"2026","featured":false,"url":"https://spacecatalog.org/object/toi-1752-b","radius_km":10798.123300000001,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-1752","host_v_mag":14.62,"uncertainties":{"radius_km":[433.71080000000006,433.71080000000006],"distance_ly":[1.0926238653510905,1.095885429128258],"host_mass_solar":[0.012,0.012],"inclination_deg":[0.13,0.29],"host_radius_solar":[0.015,0.015],"host_temperature_k":[77,77],"semi_major_axis_km":[83774.80759199998,83774.80759199998],"orbital_period_days":[0.0000015,0.0000014]},"host_mass_solar":0.524,"inclination_deg":86.75,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":0.53,"planets_in_system":2,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_spectral_type":"M1.0&plusmn0.5 V","host_temperature_k":3762,"orbital_period_days":0.9351861,"transit_midpoint_bjd":2459334.47908,"equilibrium_temperature_k":1036},"designations":[{"catalog":"Exoplanet","designation":"TOI-1752 b"},{"catalog":"Host star","designation":"TOI-1752"}],"source":{"id":"exoplanet_archive","name":"NASA Exoplanet Archive (Planetary Systems Composite Parameters)","url":"https://exoplanetarchive.ipac.caltech.edu/cgi-bin/TblView/nph-tblView?app=ExoTbls&config=PSCompPars","license":"Public domain (NASA)"},"updated_at":"2026-09-02T19:50:56.720Z","attribution":"Data from SpaceCatalog.org.
