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-241249530-b","name":"TIC 241249530 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":1058.2078443744197,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":95.3088995,"dec_deg":53.2950203,"epoch_ra_deg":95.85318,"epoch_dec_deg":53.282778,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TIC 241249530","semi_major_axis_km":95892235.1187,"periapsis_km":null,"mass_kg":9.452660506788469e+27,"mass_msun":0.00475388,"constellation":"Auriga","discovered":"2024","featured":false,"url":"https://spacecatalog.org/object/tic-241249530-b","radius_km":84789.51176469101,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TIC 241249530","host_v_mag":11.908,"eccentricity":0.9412,"uncertainties":{"mass_kg":[3.4166242795620975e+26,3.036999359610753e+26],"radius_km":[2859.6800048630002,2645.204018849],"distance_ly":[11.790553054460275,12.054739720410836],"eccentricity":[0.0009,0.0009],"host_mass_solar":[0.068,0.061],"inclination_deg":[0.51,0.57],"host_radius_solar":[0.028,0.025],"host_temperature_k":[43,43],"semi_major_axis_km":[1795174.4483999999,1495978.707],"orbital_period_days":[0.00028,0.00027],"argument_of_periastron_deg":[0.36,0.4]},"host_mass_solar":1.271,"inclination_deg":85.17,"stars_in_system":2,"discovery_method":"Transit","host_radius_solar":1.397,"planets_in_system":1,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_temperature_k":6166,"orbital_period_days":165.7719,"transit_midpoint_bjd":2458860.8007,"equilibrium_temperature_k":438.94,"argument_of_periastron_deg":42.32},"designations":[{"catalog":"Exoplanet","designation":"TIC 241249530 b"},{"catalog":"Host star","designation":"TIC 241249530"}],"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.
