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":"tic-87422071-b","name":"TIC 87422071 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":1254.9127557753875,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":273.0346013,"dec_deg":-44.2434042,"epoch_ra_deg":273.524472,"epoch_dec_deg":-44.237157,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TIC 87422071","semi_major_axis_km":15857374.294199998,"periapsis_km":null,"mass_kg":2.4485807336861694e+27,"mass_msun":0.00123143,"constellation":"Corona Australis","discovered":"2026","featured":false,"url":"https://spacecatalog.org/object/tic-87422071-b","radius_km":69275.74781963,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TIC 87422071","host_v_mag":11.982,"eccentricity":0.124,"uncertainties":{"mass_kg":[2.0879370597323927e+26,1.8981245997567207e+26],"radius_km":[6005.327991078,6219.803977092],"distance_ly":[28.036402228531266,29.3247199205124],"eccentricity":[0.06,0.073],"host_mass_solar":[0.08,0.07],"inclination_deg":[0.27,0.38],"host_radius_solar":[0.071,0.072],"host_temperature_k":[178,178],"semi_major_axis_km":[747989.3535,747989.3535],"orbital_period_days":[0.000022,0.000021],"argument_of_periastron_deg":[93.6,51.9]},"host_mass_solar":1.239,"inclination_deg":87.32,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":1.489,"planets_in_system":1,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_temperature_k":6150,"orbital_period_days":11.364929,"transit_midpoint_bjd":2458680.6599,"equilibrium_temperature_k":1110,"argument_of_periastron_deg":46.4},"designations":[{"catalog":"Exoplanet","designation":"TIC 87422071 b"},{"catalog":"Host star","designation":"TIC 87422071"}],"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.
