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-86065-b","name":"HD 86065 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":131.65660958551837,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":148.9256674,"dec_deg":-18.1069385,"epoch_ra_deg":149.244042,"epoch_dec_deg":-18.234082,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"HD 86065","semi_major_axis_km":2385637244.0529,"periapsis_km":null,"mass_kg":1.718372200159162e+28,"mass_msun":0.00864194,"constellation":"Hydra","discovered":"2022","featured":false,"url":"https://spacecatalog.org/object/hd-86065-b","radius_km":79726.25,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"HD 86065","host_v_mag":9.36,"eccentricity":0.219,"uncertainties":{"mass_kg":[4.872485847581474e+27,5.105955173345578e+27],"distance_ly":[0.1810167896327926,0.1816691023882261],"eccentricity":[0.152,0.156],"host_mass_solar":[0.092,0.092],"inclination_deg":[17.334,17.89],"host_radius_solar":[0.035862,0.049209],"host_temperature_k":[93.87,111.21],"semi_major_axis_km":[655388271.5367,717920181.4893],"orbital_period_days":[9595.00303,13279.46721],"argument_of_periastron_deg":[56.45,140.159]},"host_mass_solar":0.81,"inclination_deg":29.821,"stars_in_system":1,"discovery_method":"Radial Velocity","host_radius_solar":0.780347,"planets_in_system":1,"discovery_facility":"Multiple Observatories","host_temperature_k":4927.56,"orbital_period_days":25775.78859,"periastron_epoch_bjd":2433116.26,"equilibrium_temperature_k":52.56,"argument_of_periastron_deg":142.418},"designations":[{"catalog":"Exoplanet","designation":"HD 86065 b"},{"catalog":"Host star","designation":"HD 86065"}],"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.
