Answer:
D) its moon Charon is over half the diameter of Pluto
Explanation:
Charon is the largest of Pluto's five moons and has more than half the diameter of Pluto. For many years scientists believed that this moon was a large, monotonous ball of craters. Until July 2015, when the New Horizons spacecraft went “only” 29,000 kilometers from the satellite and revealed a landscape covered with giant mountains, huge canyons, a strange polar cap, surface color variations and landslides.
High-resolution images of Charon's hemisphere facing Pluto showed a belt of fractures and canyons that span more than 1,600 kilometers across Charon's face. Four times longer than the Grand Canyon, and twice as deep, these faults and cannons indicate a titanic geological twist in the satellite's past.
