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-95086-b","name":"HD 95086 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":281.23779522121583,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":164.2621032,"dec_deg":-68.6672917,"epoch_ra_deg":164.497059,"epoch_dec_deg":-68.810659,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"HD 95086","semi_major_axis_km":8332601397.99,"periapsis_km":null,"mass_kg":9.489774741920502e+27,"mass_msun":0.00477254,"constellation":"Carina","discovered":"2013","featured":false,"url":"https://spacecatalog.org/object/hd-95086-b","radius_km":82277.49,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"HD 95086","host_v_mag":7.36,"uncertainties":{"mass_kg":[3.7982987639153173e+27,3.7982987639153173e+27],"distance_ly":[0.7928861542294032,0.7968000307620041],"host_radius_solar":[0.03522,0.061865],"host_temperature_k":[156.92,96.18],"semi_major_axis_km":[373994676.75,373994676.75]},"host_mass_solar":1.6,"stars_in_system":1,"discovery_method":"Imaging","host_radius_solar":1.48667,"planets_in_system":1,"discovery_facility":"Paranal Observatory","host_spectral_type":"A8 III","host_temperature_k":7595,"equilibrium_temperature_k":1000},"designations":[{"catalog":"Exoplanet","designation":"HD 95086 b"},{"catalog":"Host star","designation":"HD 95086"}],"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.
