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":"hip-68126","name":"HIP 68126","class":"k3iii_orange_giant","category":"star","object_type":"K3III orange giant","mag":9.12,"mag_band":"V","abs_mag":-0.413,"abs_mag_band":"V","distance_ly":2630.293326598721,"distance_method":"parallax","ra_deg":209.201175,"dec_deg":35.198523,"epoch_ra_deg":209.494943,"epoch_dec_deg":35.067079,"epoch_moved_arcsec":0.601,"pm_ra_mas_yr":-22.43,"pm_dec_mas_yr":1.94,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Canes Venatici","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hip-68126","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"13568+3512","companions":[{"measured":2015,"magnitude":13.24,"components":null,"discoverer_code":"HJ  535","separation_arcsec":44.2,"position_angle_deg":143}],"spectral_type":"K3III","color_index_bv":1.19,"luminosity_solar":127.4089685919111,"radial_velocity_km_s":0,"proper_motion_ra_mas_yr":-22.43,"proper_motion_dec_mas_yr":1.94},"designations":[{"catalog":"HIP","designation":"HIP 68126"}],"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.
