Today is Pluto Day!
Lowell Observatory holds I Heart Pluto Festival
On Feb. 18, 1930, the young astronomer Clyde Tombaugh discovered Pluto, considered for decades a planet and “demoted” to dwarf planet status in 2008.
A few weeks later, an 11-year old girl named Venetia Burney suggested the name Pluto because of its connection to the god of the cold dark underworld.
This in-depth discussion of Pluto covers all sorts of interesting facts, including details of its discovery, how the New Horizons spacecraft gave us a much more detailed picture, and more. (Did you know that Pluto is half the size of the Moon but has five moons of its own? And someone who weighs 180 pounds on Earth would weigh 11 pounds on Pluto.)
What Makes Pluto So Intriguing | TIME
It takes Pluto slightly over 248 Earth years to orbit the sun, which means that on March 23, 2178, one Plutonian year will have elapsed since the dwarf planet was first spotted, on Feb. 18, 1930.
Here’s a cool animation showing our increasingly detailed understanding of Pluto:
And here’s an interactive image of Pluto 3D Model – NASA Solar System Exploration.
You’ll always be a planet to me, Pluto!
