This is a picture of Pluto on the left with it's moon, Charon in the upper
right. Charon is nearly as large as Pluto itself. Pluto is smaller than Earth's moon, so
you can understand why even with the most powerful telescopes it can only be seen as a
small bright speck of light.
A very interesting fact is that the length of a plutonic day (a day on Pluto) is the same as a plutonic month (the time it takes Pluto's moon Charon to orbit Pluto). Now isn't that something? That means that if a person were to stand on Pluto, directly under Charon, it would appear that Charon would remain stationary and forever be in the same spot! This would also mean that if a person was on Pluto, but on the opposite side of the planet from the moon Charon, that person would never see Charon at all! Now that's pretty strange too. So, see, Pluto and Charon are a comical set of characters even as far away as they are.
