Pluto might not be a planet anymore, but at least it has some company at the edge of our solar system.
In 2005, astronomers found a slightly smaller dwarf planet called Makemake in the Kuiper Belt in the outer reaches of the sun’s light. On Tuesday, NASA announced Makemake has a moon of its own.
The moon is nicknamed MK 2, and astronomers first discovered it a year ago using the Hubble Telescope. It's about 100 miles in diameter and resides more than 4.2 billion miles away from the sun.
