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-6054-01","name":"TOI-6054.01","class":"neptune_like_planet","category":"exoplanet","object_type":"Neptune-like planet","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":258.99099485353446,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":56.337007,"dec_deg":60.350917,"epoch_ra_deg":56.898881,"epoch_dec_deg":60.435155,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-6054","semi_major_axis_km":11414317.53441,"periapsis_km":null,"mass_kg":7.465209834739224e+25,"mass_msun":0.0000375436,"constellation":"Camelopardalis","discovered":"2024","featured":false,"url":"https://spacecatalog.org/object/toi-6054-01","radius_km":16838.184,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-6054","host_v_mag":8.020001,"eccentricity":0.164,"uncertainties":{"mass_kg":[9.555468588466207e+24,1.0152685375245345e+25],"radius_km":[956.715,956.715],"distance_ly":[0.6630759158981394,0.6663374796753069],"eccentricity":[0.055,0.052],"host_mass_solar":[0.04,0.04],"inclination_deg":[1.1,0.95],"host_radius_solar":[0.071,0.071],"host_temperature_k":[50,50],"semi_major_axis_km":[703109.99229,703109.99229],"orbital_period_days":[0.000063,0.00006],"argument_of_periastron_deg":[23,26]},"host_mass_solar":1.107,"inclination_deg":88.59,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":1.662,"planets_in_system":2,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_temperature_k":6047,"orbital_period_days":7.501428,"transit_midpoint_bjd":2458817.909,"equilibrium_temperature_k":1360,"argument_of_periastron_deg":-13},"designations":[{"catalog":"Exoplanet","designation":"TOI-6054.01"},{"catalog":"Host star","designation":"TOI-6054"}],"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.
