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":"hip-62041","name":"HIP 62041","class":"k0_orange_star","category":"star","object_type":"K0 orange star","mag":10.83,"mag_band":"V","abs_mag":5.42,"abs_mag_band":"V","distance_ly":393.90851590346483,"distance_method":"parallax","ra_deg":190.75665,"dec_deg":21.290509,"epoch_ra_deg":191.089316,"epoch_dec_deg":21.142192,"epoch_moved_arcsec":6.008,"pm_ra_mas_yr":-176.28,"pm_dec_mas_yr":-140.15,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Coma Berenices","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hip-62041","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"12431+2117","companions":[{"measured":2016,"magnitude":18.1,"components":null,"discoverer_code":"LDS5758","separation_arcsec":12.9,"position_angle_deg":137}],"radius_solar":0.781,"spectral_type":"K0","color_index_bv":0.92,"luminosity_solar":0.5915616341754738,"variable_mag_max":10.778,"variable_mag_min":10.888,"radial_velocity_km_s":0,"spectral_type_source":"SIMBAD (1984AJ.....89..702L, quality D)","surface_gravity_log_g":4.527,"surface_temperature_k":4814,"proper_motion_ra_mas_yr":-176.28,"proper_motion_dec_mas_yr":-140.15,"stellar_parameters_method":"Gaia DR3 model fit (GSP-Phot, FLAME; RUWE ≤ 1.4)","bolometric_luminosity_solar":0.2927},"designations":[{"catalog":"HIP","designation":"HIP 62041"}],"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.
