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":"hip-6078","name":"HIP 6078","class":"f7_yellow_white_star","category":"star","object_type":"F7 yellow-white star","mag":9.41,"mag_band":"V","abs_mag":2.143,"abs_mag_band":"V","distance_ly":926.5805888628958,"distance_method":"parallax","ra_deg":19.500629999999997,"dec_deg":-4.336192,"epoch_ra_deg":19.841451,"epoch_dec_deg":-4.194723,"epoch_moved_arcsec":1.163,"pm_ra_mas_yr":41.9,"pm_dec_mas_yr":-12.06,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Cetus","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hip-6078","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"01180-0420","companions":[{"measured":2019,"magnitude":10.56,"components":null,"discoverer_code":"STF 111","separation_arcsec":20.8,"position_angle_deg":330}],"spectral_type":"F7","color_index_bv":0.53,"luminosity_solar":12.100407608569544,"variable_mag_max":9.281,"variable_mag_min":9.511,"radial_velocity_km_s":0,"spectral_type_source":"SIMBAD (quality D)","proper_motion_ra_mas_yr":41.9,"proper_motion_dec_mas_yr":-12.06},"designations":[{"catalog":"HIP","designation":"HIP 6078"}],"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.
