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-69924","name":"HIP 69924","class":"k1iii_orange_giant","category":"star","object_type":"K1III orange giant","mag":10.1,"mag_band":"V","abs_mag":6.052,"abs_mag_band":"V","distance_ly":210.4233748041119,"distance_method":"parallax","ra_deg":214.650105,"dec_deg":36.089729,"epoch_ra_deg":214.932399,"epoch_dec_deg":35.965811,"epoch_moved_arcsec":3.145,"pm_ra_mas_yr":-116.14,"pm_dec_mas_yr":20.4,"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-69924","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"14186+3605","companions":[{"measured":2015,"magnitude":11.07,"components":"AB","discoverer_code":"HJL1085","separation_arcsec":377.3,"position_angle_deg":247}],"radius_solar":0.763,"spectral_type":"K1III","color_index_bv":0.746,"luminosity_solar":0.33052171686998,"variable_mag_max":10.046,"variable_mag_min":10.166,"radial_velocity_km_s":0,"surface_gravity_log_g":4.595,"surface_temperature_k":5250,"proper_motion_ra_mas_yr":-116.14,"proper_motion_dec_mas_yr":20.4,"stellar_parameters_method":"Gaia DR3 model fit (GSP-Phot, FLAME; RUWE ≤ 1.4)","bolometric_luminosity_solar":0.3979},"designations":[{"catalog":"HIP","designation":"HIP 69924"}],"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.
