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-c","name":"TOI-2267 c","class":"terrestrial_planet","category":"exoplanet","object_type":"Terrestrial planet","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":65.0614963,"dec_deg":84.9008238,"epoch_ra_deg":66.936421,"epoch_dec_deg":84.963816,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-2267 A","semi_major_axis_km":3934423.9994099997,"periapsis_km":null,"mass_kg":9.256860195076638e+24,"mass_msun":0.00000465541,"constellation":"Cepheus","discovered":"2025","featured":false,"url":"https://spacecatalog.org/object/toi-2267-c","radius_km":7271.034,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-2267 A","host_v_mag":15.56,"uncertainties":{"radius_km":[829.153,829.153],"distance_ly":[0.6196971176618125,0.6196971176618125],"host_mass_solar":[0.0079,0.0079],"inclination_deg":[0.89,1.6],"host_radius_solar":[0.0225,0.0225],"host_temperature_k":[100,100],"semi_major_axis_km":[538552.3345199999,598391.4828],"orbital_period_days":[0.0000022,0.0000022]},"host_mass_solar":0.171,"inclination_deg":89.66,"stars_in_system":2,"discovery_method":"Transit","host_radius_solar":0.2075,"planets_in_system":3,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_spectral_type":"M5 V","host_temperature_k":3030,"orbital_period_days":3.4950412,"transit_midpoint_bjd":2459525.64728,"equilibrium_temperature_k":374},"designations":[{"catalog":"Exoplanet","designation":"TOI-2267 c"},{"catalog":"Host star","designation":"TOI-2267 A"}],"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":"2026-09-09T11:17:28.634Z","attribution":"Data from SpaceCatalog.org.
