How Good Were We At Guessing What Pluto Would Look Like?

Before Tuesday, nobody really knew what Pluto looked like. But since 1933, its (now former) status as “the ninth planet” merited its inclusion in countless depictions of the Solar System. Which means up until Tuesday, every time a TV show showed a picture of Pluto they were largely guessing.

So . . . how well did they guess? In the game of “pin the proper coloration and topology on the barely-visible dwarf planet”, who came closest to winning?

The Bad

It pains me to say it, but the worst depiction of Pluto (at least on TV) was possibly the one in the very first episode of The Magic School Bus. It’s terrible: purple, weirdly-shaped (plus weirdly-shaped craters on a planet that turned out to have none), and of course Arnold takes his helmet off on the dwarf planet’s surface and doesn’t die, because Pluto is warm and has a dense, breathable atmosphere. It was a great series, and this episode is one of the better-known ones, but Frizzle’s Pluto rates dead last, earning just one Carlos.

Much more forgivably, the Animaniacs’ Pluto (from the Solar System song) wasn’t much better than Miss Frizzle’s. Blue-purple may have been popular because it feels dark and cold, and Pluto was also dark and cold. The patches of lighter and darker surface coloration take it slightly ahead of the School Bus, and earn this Pluto one-point-five Chicken Boos.

Even though it’s better than purple-Pluto, I’m a little disappointed in Bill Nye’s take on the (then) planet. I’m not dinging him for the Real World-inspired intro (that’s clearly a joke) . . . but for the rest of the episode they kept their model Plutos as very small blue-grey blobs. Neutral color, always out-of-focus . . . it’s hard to be wrong when you’re deliberately side-stepping it, but it’s hard to be right, too. Even though it was probably a deliberate choice (to avoid overstating how much we knew about Pluto) I still give the Bill Nye Pluto a paltry two misshapen lumps . . . of SCIENCE.

The Better

Pluto got a few mentions across Star Trek’s various iterations, but it wasn’t until the original series was remastered in 2009 that it actually made an on-screen appearance. Flashing past the Enterprise for just a few frames in “Tomorrow is Yesterday,” the dwarf planet looks . . . okay. (In the original episode, the scene shows only empty space around the Enterprise, and then Sulu says “we just passed Pluto”. So at least the remastered Pluto wasn’t invisible.)

When Dr. Neil deGrasse Tyson decided not to include Pluto in the Hayden Planetarium’s solar system exhibit, he may have received more letters from furious third graders than anyone else before or since. “The Pluto Files” was his televised attempt to convince those third graders not to murder him.

(Briefly) featuring a CGI Pluto (specifically, to show that Pluto is tiny next to even Mercury and therefore undeserving of “planet” status), Dr. Tyson’s Pluto isn’t quite the right color, but its dark reasons are pretty close, and the surface has good light/dark contrasts. All in all, a good effort worthy of four Neil deGrasse Tysons.

In 1991, the U.S. Postal Service created a stamp series dedicated to exploring our space-neighborhood. Stamps were issued commemorating our missions to every single planet save one: Pluto, which got a “not yet explored” where every other stamp had a satellite or probe.

Painted by Ron Miller of Virginia (holy heck, and who writes for io9! I missed the connection, so thanks, Dr. Lizardo!) the Pluto stamp features a tan-orange sphere pocked with a smattering of craters. While the real Pluto has more variation and fewer impact scars, this was painted in an era before even the blurriest color Hubble photos, making its “in the ballpark” hue just a little more impressive. And it looks nice! Four “Forever” stamps.

The Best

Yeah, it’s a little saturated, but the hue of Phineas and Ferb’s Pluto is dead on. And look at that big pale blotch, which is exactly the same color as the big pale blotch on real Pluto. Add the regions of varying darkness, varied surface topology, complete lack of craters, and the fact that it’s a papier-mâché elementary school science fair model serving as a one-off joke in a children’s cartoon about a crime-fighting platypus, and you can perhaps see why the Phineas and Ferb Pluto gets four-point-five Perrys.
