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-195692","name":"HD 195692","class":"ka2hf1mf0_yellow_white_star","category":"star","object_type":"kA2hF1mF0 yellow-white star","mag":6.37,"mag_band":"V","abs_mag":1.672,"abs_mag_band":"V","distance_ly":283.86107096719155,"distance_method":"parallax","ra_deg":307.99254,"dec_deg":25.804977,"epoch_ra_deg":308.279366,"epoch_dec_deg":25.895372,"epoch_moved_arcsec":1.225,"pm_ra_mas_yr":41.31,"pm_dec_mas_yr":-20.03,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Vulpecula","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hd-195692","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"20320+2548","companions":[{"measured":2023,"magnitude":8.75,"components":null,"discoverer_code":"STF2695","separation_arcsec":0.3,"position_angle_deg":264}],"spectral_type":"kA2hF1mF0","color_index_bv":0.281,"luminosity_solar":18.672393883829486,"radial_velocity_km_s":-18,"spectral_type_source":"SIMBAD (1995ApJS...99..135A, quality D)","proper_motion_ra_mas_yr":41.31,"proper_motion_dec_mas_yr":-20.03},"designations":[{"catalog":"HD","designation":"HD 195692"},{"catalog":"HIP","designation":"HIP 101300"},{"catalog":"HR","designation":"HR 7849"}],"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.
