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-69142","name":"HD 69142","class":"k1ii_iii_orange_bright_giant","category":"star","object_type":"K1II/III orange bright giant","mag":4.42,"mag_band":"V","abs_mag":-0.387,"abs_mag_band":"V","distance_ly":298.40471000595886,"distance_method":"parallax","ra_deg":123.51214499999999,"dec_deg":-40.34789,"epoch_ra_deg":123.749622,"epoch_dec_deg":-40.429239,"epoch_moved_arcsec":2.123,"pm_ra_mas_yr":44.84,"pm_dec_mas_yr":-65.79,"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-69142","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"08140-4021","companions":[{"measured":2011,"magnitude":9.5,"components":null,"discoverer_code":"HJ 4062","separation_arcsec":59.4,"position_angle_deg":339}],"spectral_type":"K1II/III","color_index_bv":1.17,"luminosity_solar":124.39416235583083,"radial_velocity_km_s":14,"spectral_type_source":"SIMBAD (1978MSS...C02....0H, quality D)","proper_motion_ra_mas_yr":44.84,"proper_motion_dec_mas_yr":-65.79},"designations":[{"catalog":"HD","designation":"HD 69142"},{"catalog":"HIP","designation":"HIP 40326"},{"catalog":"HR","designation":"HR 3243"}],"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.
