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-117059","name":"HIP 117059","class":"da3_8_white_dwarf","category":"star","object_type":"DA3.8 white dwarf","mag":13.11,"mag_band":"V","abs_mag":11.942,"abs_mag_band":"V","distance_ly":55.85819356052492,"distance_method":"parallax","ra_deg":355.96142999999995,"dec_deg":32.546291,"epoch_ra_deg":356.295872,"epoch_dec_deg":32.694874,"epoch_moved_arcsec":6.113,"pm_ra_mas_yr":-218.02,"pm_dec_mas_yr":-70.23,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Pegasus","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hip-117059","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"23439+3232","companions":[{"measured":2000,"magnitude":15.1,"components":"Ba,Bb","discoverer_code":"BAG  30","separation_arcsec":0.2,"position_angle_deg":215}],"spectral_type":"DA3.8","color_index_bv":1.55,"luminosity_solar":0.0014561294986160562,"variable_mag_max":12.612,"variable_mag_min":13.432,"radial_velocity_km_s":-24.3,"spectral_type_source":"SIMBAD (2011ApJ...743..138G, quality C)","proper_motion_ra_mas_yr":-218.02,"proper_motion_dec_mas_yr":-70.23},"designations":[{"catalog":"Gliese","designation":"Gl 905.2A"},{"catalog":"HIP","designation":"HIP 117059"}],"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.
