Pluto used to be a planet. Humans, in our unfaltering confidence, have downgraded it to a sub-planet, a dwarf planet, as if we know how big a planet ought to be. Even so, the arrival of New Horizons at the mysterious ice world has us all interested once again in the has-been wanderer. For ancients looking into the fixed stars of the night, the planets were all mysterious. They move against the backdrop of the stars that always maintain their places. When the planets came to be named, the gods suggested themselves. Our modern names, of course, reflect the Roman borrowings of Greek gods. Many of the Greek deities go back to ancient West Asia, where even Zeus has a strong counterpart in Hadad, or Baal, and Aphrodite is recognizable as an aspect of Ishtar.

Pluto, or Hades, was the ruler of the underworld. He was known to be decidedly rich since, well, if you can’t take it with you, someone has to inherit. Pluto, like the devourers of Ugaritic mythology, was forever hungry. Insatiable. This association of wealth and death gives us our word “plutocracy,” rule by the rich. As Bruce Springsteen sang, the poor want to be rich, and the rich want to be kings. “And a king ain’t satisfied til he rules everything.” Who says mythology isn’t true? As New Horizons flies by, we will learn more about the hellish world perpetually frozen so far from the sun. We wonder if perhaps we’ll learn more about ourselves by peering into the farthest rock from our star, Sol’s youngest child. Hades was the brother of Zeus, the king of the gods. Even Zeus had to dispose of the Titans to claim that title. In a scenario going back to ancient times, the younger generation—those we recognize as gods—struggled to make it to the top. As the paper describes it, Pluto is the last first—the last “planet” that is being closely examined the first time.

I grew up in a nine-planet solar system. I recall learning of Clyde Tombaugh’s discovery of Pluto, marveling at the math and patience required. Now that we’ve reached the outer fringes of our solar system, our little piece of the galaxy, we’re still uncertain how to occupy the earth. Many claim that science will vanquish religion completely, and that those who believe are hopelessly superstitious and uncritical in their thought. And yet, if we were to take a close look inside New Horizons, this technological wonder that has reached the farthest point of our sun’s gravitational influence, we would discover a small package of Clyde Tombaugh’s ashes inside. The man who discovered Pluto is the first to actually go there, although he’s been dead for nearly two decades. Even the most stoic of scientific minds must pause for a moment and appreciate the profound symbolism of this illogical gesture.
