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-60532","name":"HD 60532","class":"f6iv_v_yellow_white_subgiant","category":"star","object_type":"F6IV-V yellow-white subgiant","mag":4.44,"mag_band":"V","abs_mag":2.425,"abs_mag_band":"V","distance_ly":82.50843118376001,"distance_method":"parallax","ra_deg":113.513265,"dec_deg":-22.296067,"epoch_ra_deg":113.80055,"epoch_dec_deg":-22.353632,"epoch_moved_arcsec":1.65,"pm_ra_mas_yr":-40.38,"pm_dec_mas_yr":46.84,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Puppis","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hd-60532","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"spectral_type":"F6IV-V","uncertainties":{"metallicity_fe_h":[0.076,0.076]},"color_index_bv":0.521,"luminosity_solar":9.33254300796991,"metallicity_fe_h":-0.17,"radial_velocity_km_s":61,"spectral_type_source":"SIMBAD (2006AJ....132..161G, quality C)","surface_gravity_log_g":3.92,"surface_temperature_k":6222,"metallicity_fe_h_source":"Median of 10 spectroscopic determinations in 11 papers, compiled from the literature (PASTEL, Soubiran+ 2016); the error bar is the scatter between them","proper_motion_ra_mas_yr":-40.38,"proper_motion_dec_mas_yr":46.84,"stellar_parameters_method":"Spectroscopic determinations compiled from the literature (PASTEL, Soubiran+ 2016)"},"designations":[{"catalog":"Gliese","designation":"Gl 279"},{"catalog":"HD","designation":"HD 60532"},{"catalog":"HIP","designation":"HIP 36795"},{"catalog":"HR","designation":"HR 2906"}],"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.
