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-145092","name":"HD 145092","class":"k3v_orange_dwarf","category":"star","object_type":"K3V orange dwarf","mag":10.3,"mag_band":"V","abs_mag":6.191,"abs_mag_band":"V","distance_ly":216.42758756149942,"distance_method":"parallax","ra_deg":242.87369999999999,"dec_deg":-50.365472,"epoch_ra_deg":243.377809,"epoch_dec_deg":-50.435762,"epoch_moved_arcsec":2.221,"pm_ra_mas_yr":-20.62,"pm_dec_mas_yr":-80.64,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Norma","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hd-145092","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"16115-5022","companions":[{"measured":2024,"magnitude":11.39,"components":"Aa,Ab","discoverer_code":"HDS2289","separation_arcsec":0.7,"position_angle_deg":222},{"measured":2016,"magnitude":12.17,"components":"AC","discoverer_code":"GKM9353","separation_arcsec":103.4,"position_angle_deg":355},{"measured":2016,"magnitude":10.92,"components":"AB","discoverer_code":"LDS 552","separation_arcsec":104.5,"position_angle_deg":148}],"spectral_type":"K3V","color_index_bv":1.136,"luminosity_solar":0.2908037482735314,"radial_velocity_km_s":0,"spectral_type_source":"SIMBAD (1978MSS...C02....0H, quality C)","proper_motion_ra_mas_yr":-20.62,"proper_motion_dec_mas_yr":-80.64},"designations":[{"catalog":"HD","designation":"HD 145092"},{"catalog":"HIP","designation":"HIP 79336"}],"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.
