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-1416-b","name":"TOI-1416 b","class":"super_earth","category":"exoplanet","object_type":"Super-Earth","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":179.43003885520065,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":216.9234892,"dec_deg":41.9529862,"epoch_ra_deg":217.188554,"epoch_dec_deg":41.83222,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-1416","semi_major_axis_km":2842359.5432999996,"periapsis_km":null,"mass_kg":2.0783144179914e+25,"mass_msun":0.0000104521,"constellation":"Boötes","discovered":"2023","featured":false,"url":"https://spacecatalog.org/object/toi-1416-b","radius_km":10332.522,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-1416","host_v_mag":9.91,"eccentricity":0,"uncertainties":{"mass_kg":[2.806918897861948e+24,2.806918897861948e+24],"radius_km":[510.24800000000005,510.24800000000005],"distance_ly":[0.2517927235973259,0.25277119273047616],"host_mass_solar":[0.044,0.035],"inclination_deg":[1.4,1.7],"host_radius_solar":[0.028,0.036],"host_temperature_k":[70,70],"semi_major_axis_km":[44879.361209999995,44879.361209999995],"orbital_period_days":[0.0000028,0.0000028]},"host_mass_solar":0.798,"inclination_deg":85.7,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":0.793,"planets_in_system":1,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_spectral_type":"G9 V","host_temperature_k":4884,"orbital_period_days":1.0697568,"transit_midpoint_bjd":2458739.4621,"equilibrium_temperature_k":1517},"designations":[{"catalog":"Exoplanet","designation":"TOI-1416 b"},{"catalog":"Host star","designation":"TOI-1416"}],"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.
