Pluto! Dearest Pluto

Good bye to you my dwarf friend, I addressed you dearest lending the title by T. Padmanabhan (Pluto priayappetta pluto, a short story on a domestinc dog Pluto). I won’t be remembeing rest 25 assemblies, but this 26th General Assembly of the International Astronomical Union , just for single reason that we have known each other since i was nine or ten. I wouldn’t mind the new definition drafted that would accommodate only the eight largest objects from Mercury through Neptune (not counting moons) and would demote Pluto and similar bodies to “dwarf-planet” status. All I knew was what taught by my first science teacher that our solar systems consists of nine planets and at the end you were waiting to be either recited or written that I got full mark. Now that you have vanished. But I know you will still spin around the sun and in my heart. Well a note for my friends to fetch the new on this great departure:

Pluto is a dwarf planet in the solar system, having been formerly considered the ninth full planet from the Sun until it was reclassified on August 24, 2006 according to the International Astronomical Union’s (IAU) redefinition of the term “planet”. Pluto could be classified, again, among dwarf planets as the prototype of a yet-to-be-named family of trans-Neptunian objects.

Pluto has an eccentric orbit that is highly inclined with respect to the planets and takes it closer to the Sun than Neptune during a portion of its orbit. It is smaller than several natural satellites or moons in our solar system (see the list of solar system objects by radius). Pluto and its largest satellite Charon have often been considered a binary system because they are more nearly equal in size than any of the planet/moon combinations in the solar system, and because the barycentre of their orbits does not lie within either body. Two smaller moons named Nix and Hydra were discovered in 2005.

Since the discovery of Pluto in 1930, controversy has surrounded its status as a planet. The discovery of other trans-Neptunian objects (notably 2003 UB313, nicknamed “Xena”, which is even larger than Pluto) focused debate on Pluto and the definition of a planet.

Pluto’s astronomical symbol is a P-L monogram, ♇. This represents both the first two letters of the name Pluto and the initials of Percival Lowell, who had searched extensively for a ninth planet and who had founded Lowell Observatory, the observatory from which Clyde Tombaugh eventually discovered Pluto. Another symbol sometimes used for Pluto is an astrological symbol and not an astronomical one. Pluto’s astrological symbol resembles that of Neptune , but has a circle in place of the middle prong of the trident.

After years of wrangling and a week of bitter debate, astronomers voted on a sweeping reclassification of the solar system. In what many of them described as a triumph of science over sentiment, Pluto was demoted to the status of a “dwarf planet.”
