Next target of spacecraft that went past Pluto may have moon
The next flyby target of NASA's New Horizons spacecraft, which went past Pluto in 2015, might have a small moon orbiting it. Scientists earlier believed the Kuiper belt object 2014 MU69 to be peanut-shaped. Discovered in 2014, MU69 is over 6.5 billion km from Earth and appears 30 km long, or about 15-20 km in case there's a moon.
