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-352860","name":"HD 352860","class":"k6v_orange_dwarf","category":"star","object_type":"K6V orange dwarf","mag":10.29,"mag_band":"V","abs_mag":8.67,"abs_mag_band":"V","distance_ly":68.76583220866503,"distance_method":"parallax","ra_deg":311.09143500000005,"dec_deg":19.749686,"epoch_ra_deg":311.394362,"epoch_dec_deg":19.842066,"epoch_moved_arcsec":16.009,"pm_ra_mas_yr":-15.95,"pm_dec_mas_yr":-600.01,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Delphinus","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hd-352860","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"20444+1945","companions":[{"measured":2022,"magnitude":11.6,"components":null,"discoverer_code":"CAR   2","separation_arcsec":0.3,"position_angle_deg":57}],"spectral_type":"K6V","color_index_bv":1.457,"luminosity_solar":0.029648313895243406,"variable_mag_max":10.216,"variable_mag_min":10.346,"radial_velocity_km_s":3,"spectral_type_source":"SIMBAD (1986AJ.....92..139S, quality C)","proper_motion_ra_mas_yr":-15.95,"proper_motion_dec_mas_yr":-600.01},"designations":[{"catalog":"Gliese","designation":"Gl 804"},{"catalog":"HD","designation":"HD 352860"},{"catalog":"HIP","designation":"HIP 102357"}],"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.
