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-2525-b","name":"TOI-2525 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":1289.6157943644491,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":86.8509737,"dec_deg":-60.5213081,"epoch_ra_deg":86.931294,"epoch_dec_deg":-60.510886,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-2525","semi_major_axis_km":22604238.26277,"periapsis_km":null,"mass_kg":1.5944246639150888e+26,"mass_msun":0.0000801859,"constellation":"Pictor","discovered":"2023","featured":false,"url":"https://spacecatalog.org/object/toi-2525-b","radius_km":55334.807835786,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-2525","host_v_mag":14.216,"eccentricity":0.17,"uncertainties":{"mass_kg":[9.490623028644443e+24,9.490623028644443e+24],"radius_km":[714.920017161,714.920017161],"distance_ly":[7.270025659306211,7.348303189958229],"eccentricity":[0.01,0.011],"host_mass_solar":[0.042,0.042],"inclination_deg":[0.07,0.07],"host_radius_solar":[0.031,0.031],"host_temperature_k":[102,102],"semi_major_axis_km":[299195.7414,299195.7414],"orbital_period_days":[0.0017,0.0017],"argument_of_periastron_deg":[0.8,0.8]},"host_mass_solar":0.849,"inclination_deg":89.5,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":0.785,"planets_in_system":2,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_spectral_type":"K8 V","host_temperature_k":5096,"orbital_period_days":23.2856,"transit_midpoint_bjd":2458333.5289,"equilibrium_temperature_k":512.97,"argument_of_periastron_deg":345.9},"designations":[{"catalog":"Exoplanet","designation":"TOI-2525 b"},{"catalog":"Host star","designation":"TOI-2525"}],"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.
