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-11167","name":"HIP 11167","class":"yellow_white_star","category":"star","object_type":"Yellow-white star","mag":11.06,"mag_band":"V","abs_mag":9.088,"abs_mag_band":"V","distance_ly":80.89200017579584,"distance_method":"parallax","ra_deg":35.935514999999995,"dec_deg":49.333075,"epoch_ra_deg":36.380081,"epoch_dec_deg":49.455122,"epoch_moved_arcsec":0.178,"pm_ra_mas_yr":-6.6,"pm_dec_mas_yr":0.88,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Andromeda","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hip-11167","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"age_years":322044430,"mass_solar":2.313,"radius_solar":2.334,"color_index_bv":0.303,"luminosity_solar":0.020174370856119252,"radial_velocity_km_s":0,"surface_gravity_log_g":4.01,"surface_temperature_k":9729,"proper_motion_ra_mas_yr":-6.6,"proper_motion_dec_mas_yr":0.88,"stellar_parameters_method":"Gaia DR3 model fit (GSP-Phot, FLAME; RUWE ≤ 1.4) — low confidence: above 7,500 K GSP-Phot's temperature and extinction are degenerate","bolometric_luminosity_solar":35.2571},"designations":[{"catalog":"HIP","designation":"HIP 11167"}],"source":{"id":"hyg","name":"HYG Database v4.1","url":"https://github.com/astronexus/HYG-Database","license":"CC-BY-SA-4.0"},"updated_at":"2026-08-30T09:56:50.739Z","attribution":"Data from SpaceCatalog.org.
