In 2006, little Pluto bit the dust, well in terms of its planet status, at least. Physically, Pluto still remained, but eight years ago, according to Scientific American, Pluto was demoted to “dwarf status.”
But, given some recent developments surrounding Pluto’s five, yes FIVE, moons, the little guy may be making a celestial comeback.
“...Two conditions must be satisfied for an object to be called a ‘planet.’ First, the object must be in orbit around a star, while not being itself a star. Second, the object must be large enough (or more technically correct, massive enough) for its own gravity to pull it into a nearly spherical shape.”
But, why does the IAU have to be so restricting?
In their press release about the 2006 General Assembly, President Ron Ekers explained it was necessary to kick some out of the planet club:
“Modern science provides much more knowledge than the simple fact that objects orbiting the Sun appear to move with respect to the background of fixed stars. For example, recent new discoveries have been made of objects in the outer regions of our Solar System that have sizes comparable to and larger than Pluto. These discoveries have rightfully called into question whether or not they should be considered as new ‘planets.’”
Here are a few reasons why Scientific American reported that Pluto may, indeed, regain its planethood:
1. Pluto has five moons.
2. Pluto may be the largest world orbiting the sun beyond Neptune.
3. Pluto has methane in its air and has an atmosphere.
4. Pluto may be 1,471 miles across as opposed to Eris, Pluto’s rival planet that is three times farther from the sun, that is only 1,445 miles across.
Apparently, Pluto’s real diameter will be measured in July 2015 when NASA intends on doing a pluto flyby.
Will these traits be enough to put Pluto back in the planetary spotlight?
The New Yorker said, “Plutonic nationalism can be found everywhere. There are pro-Pluto Web Pages, pro-Pluto books, pro- Pluto pressure groups. They contain, and generate, heated argument and loud accusation.”
