So today we will introduce you top 10 fact about Google that you may not know.
Pluto was first discovered in 1930 by Clyde W. Tombaugh. Astronomers had always been thought that there would be a ninth planet in our Solar System, which was called planet X. After a year of observations, Tombaugh finally discovered an object in the right orbit, and declared that he had discovered Planet X. They named it Pluto. The name of the Pluto (the Roman god of the underworld) was suggested 11 years old girl. But in 2006 it is declared that Pluto is no longer a Planet. On February 17, 2018 the Washington Post wrote, that six years old Irish girl wrote to a NASA asking for Pluto’s return to the solar system planetary club. But why is Pluto no longer considered a planet in the same way as the Earth or Jupiter? Although it is in orbit around the Sun and has a roughly round shape, the argument put forward by the researchers explains the shortcomings of Pluto. Maybe, its gravitational force is not important enough to either attract and therefore agglomerate other bodies around it, or push them away. Now Scientist consider Pluto as a Dwarf Planet. According to the International Astronomical Union (I.A.U), a planet must meet the following standards:
1. It must in orbit around a star
2. It must have sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape
3. It must be neither a star nor a satellite of a planet
4. It must have cleared the neighborhood around its orbit.
Pluto meets two of the 4 standards denoted. It is in orbit around the Sun, it is neither a star and nor a satellite of a planet.
By the way, it is a planet or not, Pluto will remain our scientific consciousness for years to come. And last but not least that you force to know, it was the only planet in our Solar System that has been discovered by an American.
