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-32450","name":"HD 32450","class":"k7v_orange_dwarf","category":"star","object_type":"K7V orange dwarf","mag":8.31,"mag_band":"V","abs_mag":8.643,"abs_mag_band":"V","distance_ly":27.974758673142798,"distance_method":"parallax","ra_deg":75.61845,"dec_deg":-21.256645,"epoch_ra_deg":75.905242,"epoch_dec_deg":-21.219287,"epoch_moved_arcsec":7.016,"pm_ra_mas_yr":-141.55,"pm_dec_mas_yr":-221.74,"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-32450","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"05025-2115","companions":[{"measured":2025,"magnitude":10.6,"components":"AB","discoverer_code":"DON  91","separation_arcsec":1.1,"position_angle_deg":19},{"measured":2015,"magnitude":11.2,"components":"AC","discoverer_code":"HLN   8","separation_arcsec":32,"position_angle_deg":28}],"spectral_type":"K7V","color_index_bv":1.43,"luminosity_solar":0.030394849687701085,"radial_velocity_km_s":-17.2,"spectral_type_source":"SIMBAD (2002AJ....123.2002H, quality C)","proper_motion_ra_mas_yr":-141.55,"proper_motion_dec_mas_yr":-221.74},"designations":[{"catalog":"Gliese","designation":"Gl 185A"},{"catalog":"HD","designation":"HD 32450"},{"catalog":"HIP","designation":"HIP 23452"}],"source":{"id":"hyg","name":"HYG Database v4.1","url":"https://github.com/astronexus/HYG-Database","license":"CC-BY-SA-4.0"},"updated_at":"2026-09-01T22:58:55.274Z","attribution":"Data from SpaceCatalog.org.
