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-94692","name":"HD 94692","class":"k2_3iii_orange_giant","category":"star","object_type":"K2/3III orange giant","mag":7.08,"mag_band":"V","abs_mag":-0.187,"abs_mag_band":"V","distance_ly":926.5805888628958,"distance_method":"parallax","ra_deg":163.867875,"dec_deg":-26.978941,"epoch_ra_deg":164.189783,"epoch_dec_deg":-27.122055,"epoch_moved_arcsec":0.178,"pm_ra_mas_yr":3.31,"pm_dec_mas_yr":-5.8,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Hydra","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hd-94692","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"spectral_type":"K2/3III","color_index_bv":1.334,"luminosity_solar":103.46655758424376,"radial_velocity_km_s":0,"spectral_type_source":"SIMBAD (1982MSS...C03....0H, quality D)","proper_motion_ra_mas_yr":3.31,"proper_motion_dec_mas_yr":-5.8},"designations":[{"catalog":"HD","designation":"HD 94692"},{"catalog":"HIP","designation":"HIP 53412"}],"source":{"id":"hyg","name":"HYG Database v4.1","url":"https://github.com/astronexus/HYG-Database","license":"CC-BY-SA-4.0"},"updated_at":"2026-09-01T22:58:55.274Z","attribution":"Data from SpaceCatalog.org.
