July 14 – Calling All Planets

Today’s factismal: We did it! We have successfully visited all nine classical planets!

In lieu of a regular post today (and since I am too busy watching the newsfeed), here are my previous factismals about Pluto. Enjoy!

The New Horizons probe to Pluto carries a telescope named Ralph and a spectrometer named Alice.

Pluto’s moons are not shaped like footballs.

The Earth has less water than Europa, Pluto, or Titan (to name just three planets).

It would take 5.6 planets the size of Pluto to make one Moon (and 169 to make one Earth).

Eris “the Pluto killer” was discovered almost nine years ago.

And now, since I can’t leave well enough alone, here is a corrected version of NASA’s “family portrait” which incorrectly shows all of the planets as being the same size.
