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-62135","name":"HIP 62135","class":"kp_orange_star","category":"star","object_type":"Kp orange star","mag":11.7,"mag_band":"V","abs_mag":null,"abs_mag_band":null,"distance_ly":null,"distance_method":null,"ra_deg":191.018235,"dec_deg":-45.02203,"epoch_ra_deg":191.388905,"epoch_dec_deg":-45.169094,"epoch_moved_arcsec":0.343,"pm_ra_mas_yr":-12.64,"pm_dec_mas_yr":-2.43,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Centaurus","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/hip-62135","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"age_years":501950700,"mass_solar":2.702,"radius_solar":9.352,"spectral_type":"Kp","variable_mag_max":11.505,"variable_mag_min":11.825,"radial_velocity_km_s":0,"surface_gravity_log_g":2.811,"surface_temperature_k":4978,"proper_motion_ra_mas_yr":-12.64,"proper_motion_dec_mas_yr":-2.43,"stellar_parameters_method":"Gaia DR3 model fit (GSP-Phot, FLAME; RUWE ≤ 1.4)","bolometric_luminosity_solar":59.3712},"designations":[{"catalog":"HIP","designation":"HIP 62135"}],"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.
