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-218967","name":"HD 218967","class":"g6_8v_yellow_main_sequence_star","category":"star","object_type":"G6/8V yellow main-sequence star","mag":8.66,"mag_band":"V","abs_mag":3.973,"abs_mag_band":"V","distance_ly":282.3865179835342,"distance_method":"parallax","ra_deg":348.07956,"dec_deg":2.009359,"epoch_ra_deg":348.423316,"epoch_dec_deg":2.154481,"epoch_moved_arcsec":4.247,"pm_ra_mas_yr":120.88,"pm_dec_mas_yr":-103.66,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Pisces","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hd-218967","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"age_years":10052453000,"mass_solar":1.019,"radius_solar":1.557,"spectral_type":"G6/8V","color_index_bv":0.753,"luminosity_solar":2.242848815869284,"radial_velocity_km_s":0,"spectral_type_source":"SIMBAD (1999MSS...C05....0H, quality D)","surface_gravity_log_g":4.048,"surface_temperature_k":5676,"proper_motion_ra_mas_yr":120.88,"proper_motion_dec_mas_yr":-103.66,"stellar_parameters_method":"Gaia DR3 model fit (GSP-Phot, FLAME; RUWE ≤ 1.4)","bolometric_luminosity_solar":2.2519},"designations":[{"catalog":"HD","designation":"HD 218967"},{"catalog":"HIP","designation":"HIP 114558"}],"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.
