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-2267-d","name":"TOI-2267 d","class":"super_earth","category":"exoplanet","object_type":"Super-Earth","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":73.54826317512564,"distance_method":"NASA Exoplanet Archive sy_dist (Zúñiga-Fernández+ 2025, 2025A&A...702A..85Z)","ra_deg":65.0615,"dec_deg":84.900825,"epoch_ra_deg":66.935585,"epoch_dec_deg":84.963744,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-2267 B","semi_major_axis_km":2169169.1251499997,"periapsis_km":null,"mass_kg":2.257479454025141e+25,"mass_msun":0.0000113532,"constellation":"Cepheus","discovered":"2025","featured":false,"url":"https://spacecatalog.org/object/toi-2267-d","radius_km":11289.237000000001,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-2267 B","uncertainties":{"radius_km":[2742.583,2742.583],"distance_ly":[0.6196971176618125,0.6196971176618125],"host_mass_solar":[0.013,0.013],"inclination_deg":[0.7,0.6],"host_radius_solar":[0.03,0.03],"host_temperature_k":[157,157],"semi_major_axis_km":[104718.50949,89758.72241999999],"orbital_period_days":[0.0000023,0.0000023]},"host_mass_solar":0.0989,"inclination_deg":89,"stars_in_system":2,"discovery_method":"Transit","host_radius_solar":0.13,"planets_in_system":3,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_spectral_type":"M6 V","host_temperature_k":3022,"orbital_period_days":2.0344671,"transit_midpoint_bjd":2460625.72,"equilibrium_temperature_k":422},"designations":[{"catalog":"Exoplanet","designation":"TOI-2267 d"},{"catalog":"Host star","designation":"TOI-2267 B"}],"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.
