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-b","name":"TOI-969 b","class":"neptune_like_planet","category":"exoplanet","object_type":"Neptune-like planet","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":115.485864,"epoch_dec_deg":2.036718,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-969","semi_major_axis_km":3943399.871652,"periapsis_km":null,"mass_kg":5.434672759690155e+25,"mass_msun":0.0000273318,"constellation":"Canis Minor","discovered":"2022","featured":false,"url":"https://spacecatalog.org/object/toi-969-b","radius_km":17635.446500000002,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-969","host_v_mag":11.646,"uncertainties":{"mass_kg":[5.972167867791379e+24,5.972167867791379e+24],"radius_km":[618.6757,561.2728],"distance_ly":[1.0567466638022487,1.0655528860006007],"host_mass_solar":[0.014,0.014],"inclination_deg":[0.41,0.38],"host_radius_solar":[0.015,0.015],"host_temperature_k":[80,80],"semi_major_axis_km":[25431.638018999998,25431.638018999998],"orbital_period_days":[0.0000021,0.000002]},"host_mass_solar":0.734,"inclination_deg":86.75,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":0.671,"planets_in_system":2,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_spectral_type":"K V","host_temperature_k":4435,"orbital_period_days":1.8237305,"transit_midpoint_bjd":2459248.37709,"equilibrium_temperature_k":941},"designations":[{"catalog":"Exoplanet","designation":"TOI-969 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.
