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":"hd-110082-b","name":"HD 110082 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":342.7773067251887,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":192.5892855,"dec_deg":-88.1211107,"epoch_ra_deg":193.951523,"epoch_dec_deg":-88.267184,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"HD 110082","semi_major_axis_km":16904559.3891,"periapsis_km":null,"mass_kg":6.151332903825121e+25,"mass_msun":0.0000309359,"constellation":"Octans","discovered":"2021","featured":false,"url":"https://spacecatalog.org/object/hd-110082-b","radius_km":20409.920000000002,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"HD 110082","host_v_mag":9.23,"eccentricity":0.2,"uncertainties":{"radius_km":[637.8100000000001,637.8100000000001],"distance_ly":[0.8675759647265375,0.8675759647265375],"eccentricity":[0.1,0.2],"host_mass_solar":[0.06,0.06],"inclination_deg":[0.7,1.1],"host_radius_solar":[0.06,0.06],"host_temperature_k":[100,100],"semi_major_axis_km":[1944772.3190999997,1346380.8362999998],"orbital_period_days":[0.00004,0.00004],"argument_of_periastron_deg":[100,60]},"host_mass_solar":1.21,"inclination_deg":88.2,"stars_in_system":2,"discovery_method":"Transit","host_radius_solar":1.19,"planets_in_system":1,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_spectral_type":"F8 V","host_temperature_k":6200,"orbital_period_days":10.18271,"transit_midpoint_bjd":2458629.909,"equilibrium_temperature_k":957.2,"argument_of_periastron_deg":138},"designations":[{"catalog":"Exoplanet","designation":"HD 110082 b"},{"catalog":"Host star","designation":"HD 110082"}],"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.
