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-1782-02","name":"TOI-1782.02","class":"super_earth","category":"exoplanet","object_type":"Super-Earth","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":310.7125470754779,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":213.0787718,"dec_deg":74.4117909,"epoch_ra_deg":213.138291,"epoch_dec_deg":74.285238,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-1782","semi_major_axis_km":3850499.5939472998,"periapsis_km":null,"mass_kg":2.412755818587717e+25,"mass_msun":0.0000121341,"constellation":"Ursa Minor","discovered":"2024","featured":false,"url":"https://spacecatalog.org/object/toi-1782-02","radius_km":11729.3259,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-1782","host_v_mag":12.329,"uncertainties":{"radius_km":[1179.9485,1492.4754000000003],"distance_ly":[0.5900168872895889,0.5926261383113228],"host_mass_solar":[0.08,0.08],"host_radius_solar":[0.056,0.056],"host_temperature_k":[121,121],"semi_major_axis_km":[151243.44727769998,140173.20484589998],"orbital_period_days":[0.000001976,0.000002251]},"host_mass_solar":0.68,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":0.669,"planets_in_system":2,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_temperature_k":4336,"orbital_period_days":1.829024227,"transit_midpoint_bjd":2459632.81673,"equilibrium_temperature_k":974.95},"designations":[{"catalog":"Exoplanet","designation":"TOI-1782.02"}],"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.
