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-34365","name":"HIP 34365","class":"yellow_star","category":"star","object_type":"Yellow star","mag":10.19,"mag_band":"V","abs_mag":5.967,"abs_mag_band":"V","distance_ly":228.08148109369637,"distance_method":"parallax","ra_deg":106.85047499999999,"dec_deg":-63.962885,"epoch_ra_deg":106.899787,"epoch_dec_deg":-64.001838,"epoch_moved_arcsec":8.173,"pm_ra_mas_yr":-19.78,"pm_dec_mas_yr":305.73,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Carina","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hip-34365","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"07074-6358","companions":[{"measured":2015,"magnitude":15.66,"components":null,"discoverer_code":"NSN 273","separation_arcsec":12.3,"position_angle_deg":131}],"radius_solar":0.785,"color_index_bv":0.776,"luminosity_solar":0.3574374062644808,"variable_mag_max":10.134,"variable_mag_min":10.234,"radial_velocity_km_s":0,"surface_gravity_log_g":4.595,"surface_temperature_k":5469,"proper_motion_ra_mas_yr":-19.78,"proper_motion_dec_mas_yr":305.73,"stellar_parameters_method":"Gaia DR3 model fit (GSP-Phot, FLAME; RUWE ≤ 1.4)","bolometric_luminosity_solar":0.4989},"designations":[{"catalog":"HIP","designation":"HIP 34365"}],"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.
