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-109695","name":"HD 109695","class":"k2_3iii_orange_giant","category":"star","object_type":"K2/3III orange giant","mag":7.72,"mag_band":"V","abs_mag":-1.661,"abs_mag_band":"V","distance_ly":2452.303594307517,"distance_method":"parallax","ra_deg":189.16812,"dec_deg":-21.306641,"epoch_ra_deg":189.52065,"epoch_dec_deg":-21.454621,"epoch_moved_arcsec":0.988,"pm_ra_mas_yr":-36.71,"pm_dec_mas_yr":-4.98,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Corvus","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hd-109695","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"age_years":216718550,"mass_solar":3.701,"radius_solar":22.501,"spectral_type":"K2/3III","color_index_bv":1.352,"luminosity_solar":402.1610443342134,"radial_velocity_km_s":9,"spectral_type_source":"SIMBAD (1988MSS...C04....0H, quality D)","surface_gravity_log_g":2.227,"surface_temperature_k":4631,"proper_motion_ra_mas_yr":-36.71,"proper_motion_dec_mas_yr":-4.98,"stellar_parameters_method":"Gaia DR3 model fit (GSP-Phot, FLAME; RUWE ≤ 1.4)","bolometric_luminosity_solar":239.1883},"designations":[{"catalog":"HD","designation":"HD 109695"},{"catalog":"HIP","designation":"HIP 61548"}],"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.
