"My Very Educated Mother Just Sent Us Nine.....what?"

Familiar with the above mnemonic? (You can probably fill in the rest if you are) If not, then allow me to provide an anecdote:

Once upon a time, Masooma was in the second grade. It was a bright and sunny day--perfect weather for a treasure hunt--but Masooma did not dare look out the classroom window. Just like a diligent student, Masooma chose to center her attention towards Mrs. Leshkowitz's lesson on the Solar System.

Mrs. Leshkowitz: "Now there are NINE PLANETS in our solar system"

Masooma: "Really? Which ones?"

Mrs. Leshkowitz: "Mercury, Venus, Earth, Mars.......Pluto...But there is an easier way to remember all of these NINE PLANETS in the correct order. Repeat after me: 'My Very Educated Mother Just Sent Us Nine PIZZAS!'"

And so as the stellar public school education should have it, our dear Masooma learned of the solar system in terms of this yet-to-be-tampered-with-phrase. However, in order to truly understand our protagonist's fondness for the said phrase, it is important to mention that at that very moment, Masooma developed an admiration for Pluto. A tiny yet spunky loner, Pluto seemed akin to Masooma's own attitude. So emotionally attached was she to this particular planet that when her third grade teacher assigned her the role of Mars—Planet of War—in the class play, Masooma spent a full hour crying to her mother.

So one can only imagine my sorrow when about two and a half weeks ago, I stumbled upon this piece of news from BBC:

Pluto loses status as a planet
Astronomers have voted to strip Pluto of its status as a planet.

About 2,500 scientists meeting in Prague have adopted historic new guidelines that see the small, distant world demoted to a secondary category.

The researchers said Pluto failed to dominate its orbit around the Sun in the same way as the other planets.

The International Astronomical Union's (IAU) decision means textbooks will now have to describe a Solar System with just eight major planetary bodies. Pluto, which was discovered in 1930 by the American Clyde Tombaugh, will be referred to as a "dwarf planet".

There is a recognition that the demotion is likely to upset the public, who have become accustomed to a particular view of the Solar System.

Teary-eyed

"I have a slight tear in my eye today, yes; but at the end of the day we have to describe the Solar System as it really is, not as we would like it to be," said Professor Iwan Williams, chair of the IAU panel that has been working over recent months to define the term "planet".

The need for a strict definition was deemed necessary after new telescope technologies began to reveal far-off objects that rivaled Pluto in size.

Without a new nomenclature, these discoveries raised the prospect that textbooks could soon be talking about 50 or more planets in the Solar System.

Amid dramatic scenes in the Czech capital which saw astronomers waving yellow ballot papers in the air, the IAU voted to block this possibility - and in the process took the historic decision to relegate Pluto.

The scientists agreed that for a celestial body to qualify as a planet:
• it must be in orbit around the Sun
• it must be large enough that it takes on a nearly round shape
• it has cleared its orbit of other objects

Pluto was automatically disqualified because its highly elliptical orbit overlaps with that of Neptune. It will now join a new category of dwarf planets.

Icy reaches

Pluto's status has been contested for many years. It is further away and considerably smaller than the eight other "traditional" planets in our Solar System. At just 2,360km (1,467 miles) across, Pluto is smaller even than some moons in the Solar System.

Its orbit around the Sun is also highly tilted compared with the plane of the big planets.

In addition, since the early 1990s, astronomers have found several objects of comparable size to Pluto in an outer region of the Solar System called the Kuiper Belt.

Some astronomers have long argued that Pluto would be better categorised alongside this population of small, icy worlds.

The critical blow for Pluto came with the discovery three years ago of an object currently designated 2003 UB313. After being measured with the Hubble Space Telescope, it was shown to be some 3,000km (1,864 miles) in diameter: it is bigger than Pluto.

2003 UB313 will now join Pluto in the dwarf category, along with the biggest asteroid in the Solar System, Ceres.

Named after the god of the underworld in Roman mythology, Pluto orbits the Sun at an average distance of 5.9 billion kilometres (3.7 billion miles) taking 247.9 Earth years to complete a single circuit of the Sun.

An unmanned US spacecraft, New Horizons, is due to fly by Pluto and the Kuiper Belt in 2015.

In light of this recent development I shall pay my respects to my dear Pluto.

Dear Pluto,

You are too tiny. It’s ok; so am I. You refuse to orbit around that pompous Sun. I understand. Some times your lack of coordination finds you in a bit of a tangle with Neptune. My lack of coordination finds me walking into random people on the street all the time. So while the International Astronomical Union is quick to label you a “dwarf,” I still believe that you are nothing less than a “little planet.” Pluto, do not worry, for I have not forsaken you.

I still have one major gripe. Nine…what? Can some one please tell me: Nine…what?
