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-60764","name":"HIP 60764","class":"k8v_orange_dwarf","category":"star","object_type":"K8V orange dwarf","mag":10.56,"mag_band":"V","abs_mag":7.349,"abs_mag_band":"V","distance_ly":143.11383082195212,"distance_method":"parallax","ra_deg":186.831435,"dec_deg":75.403834,"epoch_ra_deg":187.108332,"epoch_dec_deg":75.256084,"epoch_moved_arcsec":6.824,"pm_ra_mas_yr":-224.29,"pm_dec_mas_yr":123.11,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Draco","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hip-60764","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"12276+7525","companions":[{"measured":2016,"magnitude":15.6,"components":null,"discoverer_code":"LDS1751","separation_arcsec":74.7,"position_angle_deg":110}],"radius_solar":0.723,"spectral_type":"K8V","color_index_bv":1.2,"luminosity_solar":0.10009214583192953,"variable_mag_max":10.497,"variable_mag_min":10.617,"radial_velocity_km_s":0,"spectral_type_source":"SIMBAD (1956AJ.....61..201V, quality C)","surface_gravity_log_g":4.579,"surface_temperature_k":4354,"proper_motion_ra_mas_yr":-224.29,"proper_motion_dec_mas_yr":123.11,"stellar_parameters_method":"Gaia DR3 model fit (GSP-Phot, FLAME; RUWE ≤ 1.4)","bolometric_luminosity_solar":0.1692},"designations":[{"catalog":"HIP","designation":"HIP 60764"}],"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.
