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-615-b","name":"TOI-615 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":1175.4936778013607,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":133.4086892,"dec_deg":-40.543701,"epoch_ra_deg":133.658638,"epoch_dec_deg":-40.645055,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-615","semi_major_axis_km":10142735.633459998,"periapsis_km":null,"mass_kg":8.256842009240343e+26,"mass_msun":0.000415248,"constellation":"Vela","discovered":"2023","featured":false,"url":"https://spacecatalog.org/object/toi-615-b","radius_km":121035.955697173,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-615","host_v_mag":10.825,"uncertainties":{"mass_kg":[1.5564621715616243e+26,1.6323871556713363e+26],"radius_km":[4075.04398939,3717.5840127000006],"distance_ly":[12.7494528049475,13.023424162229563],"host_mass_solar":[0.087,0.087],"inclination_deg":[0.22,0.6],"host_radius_solar":[0.055,0.055],"host_temperature_k":[100,100],"semi_major_axis_km":[388954.46381999995,463753.39916999993],"orbital_period_days":[0.0000016,0.0000025]},"host_mass_solar":1.449,"inclination_deg":86.73,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":1.732,"planets_in_system":1,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_spectral_type":"F2 V","host_temperature_k":6850,"orbital_period_days":4.6615983,"transit_midpoint_bjd":2459259.49383,"eccentricity_upper_limit":0.39,"equilibrium_temperature_k":1666},"designations":[{"catalog":"Exoplanet","designation":"TOI-615 b"},{"catalog":"Host star","designation":"TOI-615"}],"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.
