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":"cd-35-2722-b","name":"CD-35 2722 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":73.025108345268,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":92.3300147,"dec_deg":-35.8255375,"epoch_ra_deg":92.566331,"epoch_dec_deg":-35.829618,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"CD-35 2722","semi_major_axis_km":10023057336.9,"periapsis_km":null,"mass_kg":5.599467569282326e+28,"mass_msun":0.0281605,"constellation":"Columba","discovered":"2011","featured":false,"url":"https://spacecatalog.org/object/cd-35-2722-b","radius_km":110812.599726029,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"CD-35 2722","host_v_mag":11.041,"uncertainties":{"mass_kg":[8.161935778953899e+27,9.680435458759275e+27],"radius_km":[4289.519975404,3574.5999582430004],"distance_ly":[0.0432157200474685,0.0432157200474685],"host_mass_solar":[0.05,0.05],"host_radius_solar":[0.016445,0.016445],"host_temperature_k":[100,100],"semi_major_axis_km":[598391482.8,598391482.8]},"host_mass_solar":0.4,"stars_in_system":1,"discovery_method":"Imaging","host_radius_solar":0.558549,"planets_in_system":1,"discovery_facility":"Gemini Observatory","host_spectral_type":"M1 V","host_temperature_k":3689,"equilibrium_temperature_k":1800},"designations":[{"catalog":"Exoplanet","designation":"CD-35 2722 b"},{"catalog":"Host star","designation":"CD-35 2722"}],"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.
