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-92841","name":"35 Sex","class":"k2ii_iii_k1ii_iii_orange_bright_giant","category":"star","object_type":"K2II-III+K1II-III orange bright giant","mag":5.77,"mag_band":"V","abs_mag":-0.376,"abs_mag_band":"V","distance_ly":552.8073369377742,"distance_method":"parallax","ra_deg":160.83717000000001,"dec_deg":4.747669,"epoch_ra_deg":161.185516,"epoch_dec_deg":4.60682,"epoch_moved_arcsec":1.024,"pm_ra_mas_yr":19.69,"pm_dec_mas_yr":-32.96,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Sextans","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hd-92841","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"10433+0445","companions":[{"measured":2019,"magnitude":7.13,"components":"AB","discoverer_code":"STF1466","separation_arcsec":6.8,"position_angle_deg":239},{"measured":2003,"magnitude":8.1,"components":"AC","discoverer_code":"STF1466","separation_arcsec":333.8,"position_angle_deg":210}],"spectral_type":"K2II-III+K1II-III","color_index_bv":1.168,"luminosity_solar":123.14024122062172,"radial_velocity_km_s":-6,"spectral_type_source":"SIMBAD (1977AJ.....82..431L, quality C)","proper_motion_ra_mas_yr":19.69,"proper_motion_dec_mas_yr":-32.96},"designations":[{"catalog":"Bayer/Flamsteed","designation":"35 Sex"},{"catalog":"HD","designation":"HD 92841"},{"catalog":"HIP","designation":"HIP 52452"},{"catalog":"HR","designation":"HR 4193"}],"source":{"id":"hyg","name":"HYG Database v4.1","url":"https://github.com/astronexus/HYG-Database","license":"CC-BY-SA-4.0"},"updated_at":"2026-09-02T19:50:56.720Z","attribution":"Data from SpaceCatalog.org.
