Why does Pluto's planetary symbol look this way?
The symbol is in the shape of a merged "P" and "L", designed to be a monogram for Pluto and Percival Lowell

What do we mean by "Home of Pluto"?
Pluto was discovered at Lowell Observatory by Clyde Tombaugh on February 18th, 1930.

Why is Pluto's planetary symbol in red?
Well, because Pluto, as previously mentioned, was discovered at Lowell Observatory but also because Pluto is no longer a planet. Pluto was reclassified as a dwarf planet on the 13th of September* in 2006 by the International Astronomical Union (IAU). There are 5 recognized dwarf planets currently: Ceres, Pluto, Haumea, Makemake, and Eris. Scientists believe there may be over 100 waiting to be discovered.

So what is a planet then?
According to the IAU, planets are defined by three features:
1. The object must be in orbit around the Sun.
2. The object must be massive enough to be rounded by its own gravity. More specifically, its own gravity should pull it into a shape defined by hydrostatic equilibrium.
3. It must have cleared the neighborhood around its orbit.
Pluto fails to do the third, as it's mass is not great enough. However, what classifies objects like Pluto has been a long standing debate, and like all things, science changes as we learn more.

Are we sad about what happened to Pluto?
Some of us.
