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-6008-b","name":"TOI-6008 b","class":"terrestrial_planet","category":"exoplanet","object_type":"Terrestrial planet","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":75.34473250358946,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":310.4487344,"dec_deg":49.6468992,"epoch_ra_deg":310.657256,"epoch_dec_deg":49.742401,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-6008","semi_major_axis_km":1612216.2525338999,"periapsis_km":null,"mass_kg":2.3888671471165517e+25,"mass_msun":0.000012014,"constellation":"Cygnus","discovered":"2024","featured":false,"url":"https://spacecatalog.org/object/toi-6008-b","radius_km":6569.443,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-6008","host_v_mag":15.97,"uncertainties":{"radius_km":[318.90500000000003,318.90500000000003],"distance_ly":[0.09491150591557233,0.09556381867100582],"host_mass_solar":[0.011,0.011],"inclination_deg":[0.5,0.5],"host_radius_solar":[0.013,0.013],"host_temperature_k":[75,75],"semi_major_axis_km":[24234.8550534,24234.8550534],"orbital_period_days":[0.0000424,0.0000424]},"host_mass_solar":0.23,"inclination_deg":87.2,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":0.242,"planets_in_system":1,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_spectral_type":"M5.0","host_temperature_k":3075,"orbital_period_days":0.8574347,"transit_midpoint_bjd":2460078.016214,"equilibrium_temperature_k":707},"designations":[{"catalog":"Exoplanet","designation":"TOI-6008 b"},{"catalog":"Host star","designation":"TOI-6008"}],"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.
