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-7241","name":"HIP 7241","class":"m2e_red_star","category":"star","object_type":"M2e red star","mag":12.03,"mag_band":"V","abs_mag":8.733,"abs_mag_band":"V","distance_ly":148.86201082283202,"distance_method":"parallax","ra_deg":23.321849999999998,"dec_deg":-51.69431,"epoch_ra_deg":23.595114,"epoch_dec_deg":-51.555679,"epoch_moved_arcsec":4.524,"pm_ra_mas_yr":147.86,"pm_dec_mas_yr":83.35,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Phoenix","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hip-7241","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"spectral_type":"M2e","luminosity_solar":0.02797692637854649,"variable_mag_max":11.824,"variable_mag_min":12.204,"radial_velocity_km_s":0,"spectral_type_source":"SIMBAD (2014MNRAS.443.2561G, quality D)","proper_motion_ra_mas_yr":147.86,"proper_motion_dec_mas_yr":83.35},"designations":[{"catalog":"HIP","designation":"HIP 7241"}],"source":{"id":"hyg","name":"HYG Database v4.1","url":"https://github.com/astronexus/HYG-Database","license":"CC-BY-SA-4.0"},"updated_at":"2026-08-27T19:16:43.430Z","attribution":"Data from SpaceCatalog.org.
