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-5789-e","name":"TOI-5789 e","class":"neptune_like_planet","category":"exoplanet","object_type":"Neptune-like planet","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":66.72539790966908,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":302.7734475,"dec_deg":16.1897138,"epoch_ra_deg":303.080597,"epoch_dec_deg":16.269039,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-5789","semi_major_axis_km":43398342.29007,"periapsis_km":null,"mass_kg":6.933686894505791e+25,"mass_msun":0.0000348705,"constellation":"Sagitta","discovered":"2026","featured":false,"url":"https://spacecatalog.org/object/toi-5789-e","radius_km":21876.883,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-5789","host_v_mag":7.35063,"uncertainties":{"mass_kg":[5.793002831757638e+24,5.793002831757638e+24],"distance_ly":[0.12328711077692901,0.12361326715464577],"host_mass_solar":[0.027,0.032],"host_radius_solar":[0.023,0.023],"host_temperature_k":[80,80],"semi_major_axis_km":[553512.12159,553512.12159],"orbital_period_days":[0.22,0.22]},"host_mass_solar":0.821,"stars_in_system":1,"discovery_method":"Radial Velocity","host_radius_solar":0.833,"planets_in_system":4,"discovery_facility":"Multiple Observatories","host_spectral_type":"K1 V","host_temperature_k":5185,"orbital_period_days":62.98,"transit_midpoint_bjd":2460359.05,"eccentricity_upper_limit":0.071,"equilibrium_temperature_k":424},"designations":[{"catalog":"Exoplanet","designation":"TOI-5789 e"}],"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.
