Periodic comet 161P/Hartley-IRAS is being tracked as it approaches the inner solar system. Latest figures put its barycentric speed at 32.91 km/s, with perihelion due in about 56 days, in late November 2026. The comet currently sits at magnitude 14.33, observable from both hemispheres with a small telescope under dark skies, in the constellation Aquarius. Amateur astronomers are sharing observations and brightness updates as the comet slowly brightens on its way to perihelion.
