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-29232","name":"HIP 29232","class":"orange_star","category":"star","object_type":"Orange star","mag":11.05,"mag_band":"V","abs_mag":7.099,"abs_mag_band":"V","distance_ly":201.20684788259217,"distance_method":"parallax","ra_deg":92.44641,"dec_deg":-16.364454,"epoch_ra_deg":92.74733,"epoch_dec_deg":-16.370834,"epoch_moved_arcsec":7.484,"pm_ra_mas_yr":106.89,"pm_dec_mas_yr":-259.49,"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/hip-29232","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"age_years":12286673000,"mass_solar":0.736,"radius_solar":0.728,"color_index_bv":0.929,"luminosity_solar":0.1260085459088237,"variable_mag_max":10.991,"variable_mag_min":11.121,"radial_velocity_km_s":0,"surface_gravity_log_g":4.545,"surface_temperature_k":4683,"proper_motion_ra_mas_yr":106.89,"proper_motion_dec_mas_yr":-259.49,"stellar_parameters_method":"Gaia DR3 model fit (GSP-Phot, FLAME; RUWE ≤ 1.4)","bolometric_luminosity_solar":0.2301},"designations":[{"catalog":"HIP","designation":"HIP 29232"}],"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.
