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-2654-b","name":"TOI-2654 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":812.011964218713,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":52.9815377,"dec_deg":-47.9946912,"epoch_ra_deg":53.194767,"epoch_dec_deg":-47.902997,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-2654","semi_major_axis_km":null,"periapsis_km":null,"mass_kg":2.8905292480110275e+26,"mass_msun":0.000145369,"constellation":"Horologium","discovered":"2026","featured":false,"url":"https://spacecatalog.org/object/toi-2654-b","radius_km":50671.081034084,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-2654","host_v_mag":14.131,"uncertainties":{"radius_km":[3473.7457417450005,3607.2183270150003],"distance_ly":[3.538796698226666,3.5681507722211734],"inclination_deg":[1.50324,1.42684],"orbital_period_days":[0.00000352416,0.00000351285]},"host_mass_solar":0.69,"inclination_deg":87.79259,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":0.756095,"planets_in_system":1,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_temperature_k":4594.08,"orbital_period_days":2.96760425926,"transit_midpoint_bjd":2458414.30009512,"equilibrium_temperature_k":819},"designations":[{"catalog":"Exoplanet","designation":"TOI-2654 b"},{"catalog":"Host star","designation":"TOI-2654"}],"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.
