NASA’s New Horizons spacecraft made a historic New Year’s encounter with an object nicknamed Ultima Thule in the Kuiper Belt a billion miles beyond Pluto. The NASA space probe passed Ultima Thule at a distance of around 2,200 miles (3,500 kilometers) at 12:33 a.m. EST (0533 GMT) on Jan. 1, making it the most distant planetary body ever explored up close.
