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-6716-b","name":"TOI-6716 b","class":"terrestrial_planet","category":"exoplanet","object_type":"Terrestrial planet","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":61.60213352849448,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":111.657082,"dec_deg":-30.5521801,"epoch_ra_deg":111.918773,"epoch_dec_deg":-30.605561,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-6716","semi_major_axis_km":4772172.075329999,"periapsis_km":null,"mass_kg":5.440644927557946e+24,"mass_msun":0.00000273618,"constellation":"Canis Major","discovered":"2026","featured":false,"url":"https://spacecatalog.org/object/toi-6716-b","radius_km":6263.2942,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-6716","host_v_mag":14.8,"uncertainties":{"radius_km":[427.33270000000005,427.33270000000005],"distance_ly":[0.05838199161129707,0.05838199161129707],"host_mass_solar":[0.011,0.011],"inclination_deg":[0.42,0.36],"host_radius_solar":[0.015,0.015],"host_temperature_k":[80,80],"semi_major_axis_km":[463753.39916999993,463753.39916999993],"orbital_period_days":[0.0000041,0.0000054]},"host_mass_solar":0.223,"inclination_deg":89.45,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":0.231,"planets_in_system":1,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_spectral_type":"M4","host_temperature_k":3110,"orbital_period_days":4.7185898,"transit_midpoint_bjd":2459632.34484,"eccentricity_upper_limit":0.88,"equilibrium_temperature_k":369},"designations":[{"catalog":"Exoplanet","designation":"TOI-6716 b"},{"catalog":"Host star","designation":"TOI-6716"}],"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.
