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-969-c","name":"TOI-969 c","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":251.97341423058097,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":115.1366858,"dec_deg":2.0985879,"epoch_ra_deg":115.485904,"epoch_dec_deg":2.036722,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-969","semi_major_axis_km":376986634.164,"periapsis_km":null,"mass_kg":2.1448807977250945e+28,"mass_msun":0.0107869,"constellation":"Canis Minor","discovered":"2022","featured":false,"url":"https://spacecatalog.org/object/toi-969-c","radius_km":79088.44,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-969","host_v_mag":11.646,"eccentricity":0.628,"uncertainties":{"mass_kg":[1.7083121397810487e+27,2.0879370597323925e+27],"distance_ly":[1.0567466638022487,1.0655528860006007],"eccentricity":[0.036,0.043],"host_mass_solar":[0.014,0.014],"host_radius_solar":[0.015,0.015],"host_temperature_k":[80,80],"semi_major_axis_km":[43383382.50299999,40391425.089],"orbital_period_days":[280,290],"argument_of_periastron_deg":[7.3,7.8]},"host_mass_solar":0.734,"stars_in_system":1,"discovery_method":"Radial Velocity","host_radius_solar":0.671,"planets_in_system":2,"discovery_facility":"Multiple Observatories","host_spectral_type":"K V","host_temperature_k":4435,"orbital_period_days":1700,"transit_midpoint_bjd":2460640,"equilibrium_temperature_k":96.4,"argument_of_periastron_deg":208.5},"designations":[{"catalog":"Exoplanet","designation":"TOI-969 c"},{"catalog":"Host star","designation":"TOI-969"}],"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.
