why should pluto be a planet again
Today is a historic dayБone that will bring joy to the hundreds of millions of Pluto lovers around the globe. The International Astronomical Union (IAU), the body that is responsible for naming and classifying objects in the cosmos, has just announced that Pluto has been reclassified as a major planet. That s right, the little dwarf will be rejoining the ranks of Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Planet-X (the planet that will surely spell doom for all humanity). As many of you know, in 2006, the IAU made theirб
everyone s favorite planet to a dwarf planet. Their reasoning was that too many people would confuse Pluto (the doggyб of Disney fame) with Pluto (the planet, of space and stuff). Immediately after this 2006 announcement, the public exploded with outrage. There were a number of campaigns launched that were aimed at ensuring that Pluto was reinstated as a planet. These met with no success. Pluto was officially classified as a dwarf planet. But all of that just changed, After years of deliberation, the IAU that they have reclassified the icy worldБthey upgraded Pluto back to its proper standing as a planet. We simply underestimated the public s attachment to Pluto. We realized our error shortly after the decision came down to demote it, said Dr. Amy Joggy, professor at the Institute of Planetary Studies and head of the IAU s Planetary Classification and Experimental Nomenclature Task Force.
We didn t think anyone would really care if a little clump of ice and rock on the outskirts of the solar system was reclassified. Clearly, we dun messed up, and that makes me super sad face. Today, we take steps to correct this most grievous of errors. In addition to Pluto s reclassification, Dr. Joggy has also proposed that the IAU create a new category of planet called a hyper-planet. These hyper-planets, according to Dr. Joggy, are like regular planets but at least two times as awesome (thanks to the fancy, fancy name). It has also been proposed that Pluto be made an honorary member of this new planetary class. In all honesty, we feel bad for the way we treated Pluto and, more importantly, all those that cared about it so greatly- the public showed us our error. Hopefully, the new class of planet will be created without a hitch, and Pluto will be added as the first member. It s only fair. Say it with me now, Yay! also, have a happy April Fool s. A high-resolution enhanced colour image of Pluto captured on 14 July 2015. Blues, yellows, oranges and reds combine on the dwarf planet's complex surface. The image reveals details on scales as small as 0. 8 miles (1. 3km) It's been more than ten years since Pluto was but the decision could be reversed if a group of scientists get their way. Alan Stern, the head of Nasa's mission to Pluto, and a host of other scientists from the space agency and universities have proposed a new definition for a planet.
If it is adopted the change would make Pluto and another 109 objects in our solar system official planets. Based on their studies, the team has created the following definition of what a planet is and published it in a. A planet is a sub-stellar mass body that has never undergone nuclear fusion and that has sufficient self-gravitation to assume a spheroidal shape adequately described by a triaxial ellipsoid regardless of its orbital parameters, the proposed definition reads. The team argues it is possible to make the definition simple enough for young children to understand. As part of this, the planetary scientists say it can be shortened to: round objects in space that are smaller than stars. With the above definition of a planet, we count at least 110 known planets in our Solar System, Stern and colleagues write in the paper, which concludes by saying discussions with members of the public have shown there is support for a new definition. However, for a 110 planet solar system to become official, the definition would have to be approved by the. The body, which was formed in 1919, is responsible for organising international space conferences and the definition of fundamental astronomical and physical constants. In 2006, it was the IAU that changed the definition of a planet and excluded Pluto from the list of eight known planets. was revealed at the IAU's conference in 2006, and gave the following definition of a planet in our Solar System.
A 'planet'В  is a celestial body that (a) is in orbit around the Sun, (b)В has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, and (c) has cleared the neighbourhood around its orbit. The current definition means is currently known as a dwarf planet. WIRED has contacted the IAU asking whether the new proposal for a definition will be looked at by its researchers. In the new paper, which the scientists plan to put forward to the IAU, the current definition is described as technically flawed - it only recognises planets as objects that are orbiting our Sun and not other stars. It also says the need for zone-clearing means no planet in our meets the criteria for planets. The authors argue the new definition is geophysical and based on the physics of the world itself. Understanding the natural organisation of the Solar System is much more informative than rote memorisation, they explain. When Stern was challenged on what a 110-planet Solar System would mean for children trying to memorise the planets, he said it was an outdated approach. So 20th century, he said on Twitter. Do you have mnemonics for the names of all the stars or asteroids? Rivers/ Mountains? Course not.
