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-113244","name":"HIP 113244","class":"m1v_red_dwarf","category":"star","object_type":"M1V red dwarf","mag":11.23,"mag_band":"V","abs_mag":9.288,"abs_mag_band":"V","distance_ly":79.76447757802906,"distance_method":"parallax","ra_deg":343.98675,"dec_deg":5.755094,"epoch_ra_deg":344.329301,"epoch_dec_deg":5.896376,"epoch_moved_arcsec":11.932,"pm_ra_mas_yr":356.62,"pm_dec_mas_yr":-269.74,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Pisces","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hip-113244","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wds_id":"22560+0546","age_years":9800712000,"companions":[{"measured":2016,"magnitude":16.25,"components":null,"discoverer_code":"LDS5021","separation_arcsec":17.2,"position_angle_deg":285}],"mass_solar":0.567,"radius_solar":0.683,"spectral_type":"M1V","color_index_bv":1.433,"luminosity_solar":0.01678031078290955,"variable_mag_max":11.136,"variable_mag_min":11.286,"radial_velocity_km_s":0,"spectral_type_source":"SIMBAD (1986AJ.....92..139S, quality C)","surface_gravity_log_g":4.152,"surface_temperature_k":3453,"proper_motion_ra_mas_yr":356.62,"proper_motion_dec_mas_yr":-269.74,"stellar_parameters_method":"Gaia DR3 model fit (GSP-Phot, FLAME; RUWE ≤ 1.4)","bolometric_luminosity_solar":0.0602},"designations":[{"catalog":"Gliese","designation":"GJ 4304A"},{"catalog":"HIP","designation":"HIP 113244"}],"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.
