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-86162","name":"HIP 86162","class":"m3_0v_red_dwarf","category":"star","object_type":"M3.0V red dwarf","mag":9.15,"mag_band":"V","abs_mag":10.87,"abs_mag_band":"V","distance_ly":14.769013095769575,"distance_method":"parallax","ra_deg":264.109245,"dec_deg":68.339141,"epoch_ra_deg":264.073398,"epoch_dec_deg":68.312056,"epoch_moved_arcsec":34.929,"pm_ra_mas_yr":-320.47,"pm_dec_mas_yr":-1269.55,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Draco","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hip-86162","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"17364+6820","companions":[{"measured":1999,"magnitude":11.38,"components":"BC","discoverer_code":"STU  10","separation_arcsec":301.6,"position_angle_deg":62}],"radius_solar":0.489,"spectral_type":"M3.0V","color_index_bv":1.505,"luminosity_solar":0.003908408957924021,"radial_velocity_km_s":-23.2,"spectral_type_source":"SIMBAD (2015A&A...577A.128A, quality C)","surface_gravity_log_g":4.013,"surface_temperature_k":3192,"proper_motion_ra_mas_yr":-320.47,"proper_motion_dec_mas_yr":-1269.55,"stellar_parameters_method":"Gaia DR3 model fit (GSP-Phot, FLAME; RUWE ≤ 1.4)","bolometric_luminosity_solar":0.0214},"designations":[{"catalog":"Exoplanet host","designation":"GJ 687"},{"catalog":"Gliese","designation":"Gl 687"},{"catalog":"HIP","designation":"HIP 86162"}],"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.
