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-130325","name":"HD 130325","class":"k1iiicn0_5_orange_giant","category":"star","object_type":"K1IIICN0.5 orange giant","mag":6.34,"mag_band":"V","abs_mag":1.08,"abs_mag_band":"V","distance_ly":367.70739561234564,"distance_method":"parallax","ra_deg":221.97895499999998,"dec_deg":-12.840007,"epoch_ra_deg":222.346137,"epoch_dec_deg":-12.953093,"epoch_moved_arcsec":2.797,"pm_ra_mas_yr":49.05,"pm_dec_mas_yr":-92.64,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Libra","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hd-130325","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"spectral_type":"K1IIICN0.5","uncertainties":{"metallicity_fe_h":[0.1,0.1]},"color_index_bv":1.097,"luminosity_solar":32.210687912834345,"metallicity_fe_h":-0.13,"radial_velocity_km_s":33,"spectral_type_source":"SIMBAD (1989ApJS...71..245K, quality C)","surface_gravity_log_g":2.1,"surface_temperature_k":4641,"metallicity_fe_h_source":"One spectroscopic determination, compiled from the literature (PASTEL, Soubiran+ 2016)","proper_motion_ra_mas_yr":49.05,"proper_motion_dec_mas_yr":-92.64,"stellar_parameters_method":"Spectroscopic determinations compiled from the literature (PASTEL, Soubiran+ 2016)"},"designations":[{"catalog":"HD","designation":"HD 130325"},{"catalog":"HIP","designation":"HIP 72373"},{"catalog":"HR","designation":"HR 5518"}],"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.
