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-67090","name":"HIP 67090","class":"m1v_red_dwarf","category":"star","object_type":"M1V red dwarf","mag":9.79,"mag_band":"V","abs_mag":9.181,"abs_mag_band":"V","distance_ly":43.1824520969414,"distance_method":"parallax","ra_deg":206.27112,"dec_deg":17.78544,"epoch_ra_deg":206.598054,"epoch_dec_deg":17.637003,"epoch_moved_arcsec":50.306,"pm_ra_mas_yr":451.03,"pm_dec_mas_yr":-1831.59,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Boötes","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hip-67090","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"13451+1747","age_years":12881973000,"companions":[{"measured":2015,"magnitude":12.07,"components":"AB","discoverer_code":"BUP 153","separation_arcsec":111.5,"position_angle_deg":335},{"measured":2015,"magnitude":9.49,"components":"AC","discoverer_code":"BUP 153","separation_arcsec":446.9,"position_angle_deg":107}],"mass_solar":0.53,"radius_solar":0.482,"spectral_type":"M1V","color_index_bv":1.42,"luminosity_solar":0.01851825243638179,"metallicity_fe_h":0.59,"radial_velocity_km_s":20.4,"spectral_type_source":"SIMBAD (2010MNRAS.403.1949K, quality C)","surface_gravity_log_g":4.766,"surface_temperature_k":3846,"metallicity_fe_h_source":"One spectroscopic determination, compiled from the literature (PASTEL, Soubiran+ 2016)","proper_motion_ra_mas_yr":451.03,"proper_motion_dec_mas_yr":-1831.59,"stellar_parameters_method":"Gaia DR3 model fit (GSP-Phot, FLAME; RUWE ≤ 1.4)","bolometric_luminosity_solar":0.047},"designations":[{"catalog":"Gliese","designation":"Gl 525"},{"catalog":"HIP","designation":"HIP 67090"}],"source":{"id":"hyg","name":"HYG Database v4.1","url":"https://github.com/astronexus/HYG-Database","license":"CC-BY-SA-4.0"},"updated_at":"2026-09-01T22:58:55.274Z","attribution":"Data from SpaceCatalog.org.
