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-95690","name":"HD 95690","class":"k2v_orange_dwarf","category":"star","object_type":"K2V orange dwarf","mag":8.45,"mag_band":"V","abs_mag":5.264,"abs_mag_band":"V","distance_ly":141.43803935324348,"distance_method":"parallax","ra_deg":165.86655,"dec_deg":54.525762,"epoch_ra_deg":166.26243,"epoch_dec_deg":54.381841,"epoch_moved_arcsec":4.082,"pm_ra_mas_yr":-129.64,"pm_dec_mas_yr":81.35,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Ursa Major","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hd-95690","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"11035+5432","age_years":9569616000,"companions":[{"measured":2017,"magnitude":9.64,"components":null,"discoverer_code":"A  1590","separation_arcsec":1.5,"position_angle_deg":327}],"mass_solar":0.849,"radius_solar":0.974,"spectral_type":"K2V","color_index_bv":0.89,"luminosity_solar":0.6829674408079636,"radial_velocity_km_s":0,"spectral_type_source":"SIMBAD (quality D)","surface_gravity_log_g":4.352,"surface_temperature_k":4983,"proper_motion_ra_mas_yr":-129.64,"proper_motion_dec_mas_yr":81.35,"stellar_parameters_method":"Gaia DR3 model fit (GSP-Phot, FLAME; RUWE ≤ 1.4)","bolometric_luminosity_solar":0.5029},"designations":[{"catalog":"HD","designation":"HD 95690"},{"catalog":"HIP","designation":"HIP 54040"}],"source":{"id":"hyg","name":"HYG Database v4.1","url":"https://github.com/astronexus/HYG-Database","license":"CC-BY-SA-4.0"},"updated_at":"2026-09-02T18:38:07.546Z","attribution":"Data from SpaceCatalog.org.
