Quiz Answer Key and Fun Facts

A fitting name, not just because Pluto is so cold and far away, but because the name combines the letters P and L, the initials of the planets 'godfather,' Percival Lowell.

The observatory is one of the oldest in the USA and has been responsible for other discoveries such as oxygen on Ganymede, one of Jupiter's satellites.

6. Two previously undiscovered moons of Pluto were discovered in 2005. One was named Nix. Which name was given to the second one?

The two moons were found by the team operating the Hubble Space Telescope, with the name of Hydra being allocated partly due to the starting initial of Hubble.
