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-1266-d","name":"TOI-1266 d","class":"super_earth","category":"exoplanet","object_type":"Super-Earth","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":117.45478243059821,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":197.9965833,"dec_deg":65.8336973,"epoch_ra_deg":198.242379,"epoch_dec_deg":65.690816,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-1266","semi_major_axis_km":22634157.83691,"periapsis_km":null,"mass_kg":2.1977577753472276e+25,"mass_msun":0.0000110528,"constellation":"Draco","discovered":"2025","featured":false,"url":"https://spacecatalog.org/object/toi-1266-d","radius_km":11097.894,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-1266","host_v_mag":12.941,"uncertainties":{"mass_kg":[6.629106333248432e+24,6.270776261180948e+24],"distance_ly":[0.0962161314264393,0.0962161314264393],"host_mass_solar":[0.021,0.021],"host_radius_solar":[0.0079,0.0077],"host_temperature_k":[77,77],"semi_major_axis_km":[359034.88967999996,359034.88967999996],"orbital_period_days":[0.049,0.062]},"host_mass_solar":0.437,"stars_in_system":1,"discovery_method":"Transit Timing Variations","host_radius_solar":0.4232,"planets_in_system":3,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_spectral_type":"M2","host_temperature_k":3563,"orbital_period_days":32.509,"transit_midpoint_bjd":2458729.03,"eccentricity_upper_limit":0.087,"equilibrium_temperature_k":288},"designations":[{"catalog":"Exoplanet","designation":"TOI-1266 d"},{"catalog":"Host star","designation":"TOI-1266"}],"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.
