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-3364-b","name":"TOI-3364 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":906.3853121110528,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":144.5377709,"dec_deg":-49.3352226,"epoch_ra_deg":144.778917,"epoch_dec_deg":-49.455912,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-3364","semi_major_axis_km":10097856.27225,"periapsis_km":null,"mass_kg":3.169868081593724e+27,"mass_msun":0.00159417,"constellation":"Vela","discovered":"2023","featured":false,"url":"https://spacecatalog.org/object/toi-3364-b","radius_km":77997.771761114,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-3364","host_v_mag":11.875,"eccentricity":0,"uncertainties":{"mass_kg":[2.4675619796837367e+26,2.2777495197080647e+26],"radius_km":[2287.743978378,2716.696014187],"distance_ly":[8.026708455609056,8.170217261804423],"host_mass_solar":[0.083,0.059],"inclination_deg":[0.68,0.75],"host_radius_solar":[0.03,0.036],"host_temperature_k":[91,95],"semi_major_axis_km":[239356.59312,164557.65777],"orbital_period_days":[0.0000069,0.0000069]},"host_mass_solar":1.186,"inclination_deg":88.79,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":1.419,"planets_in_system":1,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_temperature_k":5706,"orbital_period_days":5.8768918,"transit_midpoint_bjd":2459090.99481,"equilibrium_temperature_k":1264},"designations":[{"catalog":"Exoplanet","designation":"TOI-3364 b"},{"catalog":"Host star","designation":"TOI-3364"}],"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.
