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-95175","name":"HD 95175","class":"k3_orange_star","category":"star","object_type":"K3 orange star","mag":8.85,"mag_band":"V","abs_mag":5.954,"abs_mag_band":"V","distance_ly":123.77862843814813,"distance_method":"parallax","ra_deg":164.89452,"dec_deg":17.999389,"epoch_ra_deg":165.249969,"epoch_dec_deg":17.853791,"epoch_moved_arcsec":8.822,"pm_ra_mas_yr":-235.87,"pm_dec_mas_yr":-231.81,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Leo","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hd-95175","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"10596+1800","companions":[{"measured":2023,"magnitude":11.62,"components":null,"discoverer_code":"HDS1568","separation_arcsec":0.2,"position_angle_deg":280}],"spectral_type":"K3","color_index_bv":0.98,"luminosity_solar":0.3617428867642181,"radial_velocity_km_s":16.1,"spectral_type_source":"SIMBAD (1985ApJS...59..197B, quality D)","proper_motion_ra_mas_yr":-235.87,"proper_motion_dec_mas_yr":-231.81},"designations":[{"catalog":"HD","designation":"HD 95175"},{"catalog":"HIP","designation":"HIP 53731"}],"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.
