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-7510-b","name":"TOI-7510 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":812.1489498973541,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":273.728188,"dec_deg":-54.4340547,"epoch_ra_deg":274.281395,"epoch_dec_deg":-54.425918,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-7510","semi_major_axis_km":15244023.02433,"periapsis_km":null,"mass_kg":1.0809623840702398e+26,"mass_msun":0.0000543632,"constellation":"Telescopium","discovered":"2025","featured":false,"url":"https://spacecatalog.org/object/toi-7510-b","radius_km":46623.911,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-7510","host_v_mag":11.989,"eccentricity":0.0572,"uncertainties":{"mass_kg":[1.0152685375245345e+25,1.0152685375245345e+25],"radius_km":[1466.9630000000002,1466.9630000000002],"distance_ly":[8.277848866450947,8.444188619086487],"eccentricity":[0.0033,0.0033],"host_mass_solar":[0.065,0.065],"inclination_deg":[0.72,0.72],"host_radius_solar":[0.026,0.026],"host_temperature_k":[50,50],"semi_major_axis_km":[299195.7414,299195.7414],"argument_of_periastron_deg":[5.6,5.6]},"host_mass_solar":1.063,"inclination_deg":90.03,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":1.035,"planets_in_system":3,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_spectral_type":"G3","host_temperature_k":5720,"orbital_period_days":11.530869,"transit_midpoint_bjd":2458656.213656,"equilibrium_temperature_k":878,"argument_of_periastron_deg":95.9},"designations":[{"catalog":"Exoplanet","designation":"TOI-7510 b"}],"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.
