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-35162","name":"HD 35162","class":"g8_k0ii_iii_a2_3_yellow_bright_giant","category":"star","object_type":"G8/K0II/III+A2/3 yellow bright giant","mag":5.06,"mag_band":"V","abs_mag":-0.105,"abs_mag_band":"V","distance_ly":351.84086630555925,"distance_method":"parallax","ra_deg":80.442735,"dec_deg":-24.772981,"epoch_ra_deg":80.718717,"epoch_dec_deg":-24.746329,"epoch_moved_arcsec":0.648,"pm_ra_mas_yr":-20.55,"pm_dec_mas_yr":-12.99,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Lepus","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hd-35162","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"05218-2446","companions":[{"measured":2015,"magnitude":6.58,"components":"AB","discoverer_code":"HJ 3752","separation_arcsec":3.5,"position_angle_deg":91},{"measured":2015,"magnitude":9.32,"components":"AC","discoverer_code":"HJ 3752","separation_arcsec":59.8,"position_angle_deg":104}],"spectral_type":"G8/K0II/III+A2/3","uncertainties":{"metallicity_fe_h":[0.185,0.185]},"color_index_bv":0.662,"luminosity_solar":95.94006315159336,"metallicity_fe_h":-0.125,"radial_velocity_km_s":5,"spectral_type_source":"SIMBAD (1988MSS...C04....0H, quality C)","surface_gravity_log_g":2.5,"surface_temperature_k":5153,"metallicity_fe_h_source":"Median of 2 spectroscopic determinations in 3 papers, compiled from the literature (PASTEL, Soubiran+ 2016); the error bar is the scatter between them","proper_motion_ra_mas_yr":-20.55,"proper_motion_dec_mas_yr":-12.99,"stellar_parameters_method":"Spectroscopic determinations compiled from the literature (PASTEL, Soubiran+ 2016)"},"designations":[{"catalog":"HD","designation":"HD 35162"},{"catalog":"HIP","designation":"HIP 25045"},{"catalog":"HR","designation":"HR 1771"}],"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.
