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-6068","name":"HD 6068","class":"f2v_yellow_white_main_sequence_star","category":"star","object_type":"F2V yellow-white main-sequence star","mag":9.66,"mag_band":"V","abs_mag":2.713,"abs_mag_band":"V","distance_ly":799.4027586561838,"distance_method":"parallax","ra_deg":15.398505,"dec_deg":-30.937409,"epoch_ra_deg":15.720122,"epoch_dec_deg":-30.792876,"epoch_moved_arcsec":0.939,"pm_ra_mas_yr":34.42,"pm_dec_mas_yr":-7.55,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Sculptor","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hd-6068","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"spectral_type":"F2V","color_index_bv":0.47,"luminosity_solar":7.158136899114736,"radial_velocity_km_s":0,"spectral_type_source":"SIMBAD (1982MSS...C03....0H, quality C)","surface_temperature_k":6347,"proper_motion_ra_mas_yr":34.42,"proper_motion_dec_mas_yr":-7.55,"stellar_parameters_method":"Spectroscopic determinations compiled from the literature (PASTEL, Soubiran+ 2016)"},"designations":[{"catalog":"HD","designation":"HD 6068"},{"catalog":"HIP","designation":"HIP 4799"}],"source":{"id":"hyg","name":"HYG Database v4.1","url":"https://github.com/astronexus/HYG-Database","license":"CC-BY-SA-4.0"},"updated_at":"2026-08-27T19:16:43.430Z","attribution":"Data from SpaceCatalog.org.
