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-9059","name":"HIP 9059","class":"k2v_orange_dwarf","category":"star","object_type":"K2V orange dwarf","mag":9.62,"mag_band":"V","abs_mag":6.24,"abs_mag_band":"V","distance_ly":154.64965574541563,"distance_method":"parallax","ra_deg":29.1597,"dec_deg":43.912756,"epoch_ra_deg":29.570499,"epoch_dec_deg":44.043405,"epoch_moved_arcsec":6.031,"pm_ra_mas_yr":-201.23,"pm_dec_mas_yr":-103.09,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Andromeda","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hip-9059","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"01566+4355","companions":[{"measured":2015,"magnitude":19.69,"components":null,"discoverer_code":"LEP   5","separation_arcsec":96.1,"position_angle_deg":188}],"spectral_type":"K2V","color_index_bv":0.92,"luminosity_solar":0.2779713267759287,"radial_velocity_km_s":0,"spectral_type_source":"SIMBAD (2018A&A...612A..96F, quality C)","proper_motion_ra_mas_yr":-201.23,"proper_motion_dec_mas_yr":-103.09},"designations":[{"catalog":"HIP","designation":"HIP 9059"}],"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.
