New Horizons Collects First Science on a Post-Pluto Object

Explanation: In April 2016, NASA's New Horizons spacecraft observed 1994 JR1, a 90–mile (145–kilometer) wide Kuiper Belt object (KBO) orbiting more than 3 billion miles (5 billion kilometers) from the sun, for the second time. Taken with the spacecraft's Long Range Reconnaissance Imager (LORRI) on April 7–8 from a distance of about 69 million miles (111 million kilometers), the images shatter New Horizons' own record for the closest-ever views of this KBO in November 2015, when New Horizons detected JR1 from 170 million miles (280 million kilometers) away.
