  • Neptune

    Why PLUTO is not considered as a planet


PLUTO

Pluto was discovered by a scientist named Clyde Tombaugh in 1930. Pluto is a dwarf(small) planet it is found in Kuiper Belt(a ring of bodies beyond Neptune). It was the first Kuiper Belt object discovered. Pluto it is the largest known Plutoid(ice dwarf).

According to IAU(International Astronomical Union) PLUTO is not the only dwarf planet, there are 5 other dwarf bodies-
  • Ceres(1801)
  • Pluto(1930)
  • Eris(2005)
  • Makemake(2005)
  • Haumea(2004)

Definition of a Planet
Definition of  Planet is defined by the IAU(International Astronomical Union). Here, Professional PhD level astronomers work. IAU(International Astronomical Union) headquarter is in Paris, France. India is the member of this Union. Any large object can be defined as a planet if it has these 3 points-
  • Have enough gravity to pull itself into a more or less Spherical shape,
  • Have cleared pretty much everything else out of its orbital path and
  • It has to orbit the SUN.
↦Pluto does have these points, that's why Pluto is not considered as a PLANET.

➢What if we consider Pluto as a planet?
➣There are many other dwarf planets then we have to consider other dwarf planets also a complete Planet. Some studies found its the largest object. There are many other large objects like Eris, Houmia, Makemake and various other objects found beyond Neptune.

NASA
According to NASA's(National Aeronautics and Space Administration) Chief Jim Bridenstine has said that in my views Pluto is a planet. He said that we are studying Pluto as a planet and the students have seen in their science books that Pluto is a PLANET early in 2000. [Headquarter of NASA(National Aeronautics and Space Administration) is in Washington D.C, United States.

What is GDP and GNP and Methods to Calculate it In this article we will know what is GDP and how it is calculated. In the next parts of this article we will discuss about how NNP, NDP, GNP, GDP, NNPFC, NNPMP are different from each other. We will also discuss what the GDP at constant price and GDP at current price are. By the way, all the notes related to Economics are being added on this page, which you cannot afford to miss. By the way, you can find all the notes of Economics on this page. Gross Domestic Product  All those things which are produced inside the country or within the country economic value.

Difference between Gross Domestic Product at Market Price(MP) and Gross Domestic Product at Factor Cost(FC) In the previous article, we learned what GDP is and how to calculate it. If you didn't seen my previous article then click this link What is GDP and GNP and Methods to calculate it . But at the end of that article, I said to be continued so I am writing this article. You must have read about GDP at market price (MC) and GDP at factor price (FC) many times. But the clean language of economics overwhelms us. I do not know why they serve things in books, but some terms of economics are very easy to understand. Take GDP (mp) and GDP (fc) only. Gross Domestic Product at Market Price It is clear from the name itself that there is talk of market price here. The price / price of a product or service that we buy from the market. Suppose you and we go to the hotel and eat tandoori roti. When the food starts to rise, the waiter comes and stops the bill. Then we both start argu...

Goods and Services Tax(GST) The Rajya Sabha passed the Goods and Services Tax(GST) Bill unopposed on 3 August 2016. This bill has already been passed by the Lok Sabha. Thus, this bill has got the approval of both the houses. It is being described as a historical event. Economists say that since 1947, this is a step of India's economic reform. The third meeting of the GST Council was held on 19/10/2016 . In this, it was considered to determine the rate for GST. It was attended by Finance Minister of the Central Government and representatives of various states. No final decision on GST rate could be reached in the meeting. Most states objected to the imposition of additional cess on demerit goods. Now this meeting will again be held on 3-4 November 2016 in which the final decision will be taken on the tax structure of GST. To understand GST (Good and Services Tax) first we have to first understand the tax structure of India. Let's first understand the tax structure o...
