Pluto System Family Portrait

Explanation: The four largest bodies in the Pluto system, to scale: Pluto, Charon, Nix, and Hydra. The images were taken at a variety of times, from 16 to 10 hours before New Horizons' closest approach to Pluto. They have been resized to a common scale (how they would appear if New Horizons were 500,000 kilometers away). Not pictured are Kerberos and Styx; images of those moons of comparable quality have not yet been returned by New Horizons.
