After being reduced to a dwarf planet on August 24, 2006, the results of the General Assembly of the International Astronomical Union IAU (International Astronomical Union) in Prague, Czech Republic. Recently, Pluto was reinstated as a “planet” again after 17 years, when it had been a planet for 76 years in the past.
This causes this star to become the 9th planet of the solar system again on “April Fools Day”.
Currently, Pluto retains its status as a dwarf planet. The reason why Pluto was demoted to dwarf planet status It is a result of the International Astronomical Union. There was a meeting and a new definition of the planet was established.
1. Planets must revolve primarily around the sun.
2. It has enough mass to shape it into a spherical or nearly spherical shape.
3. The orbit must not overlap with another star.
And with the definition given in the last point, Pluto which has an elliptical orbit and overlaps with Neptune cannot be counted as a planet and was reduced to the status of only a dwarf planet in the solar system
Orbiting the sun of the 8 planets in the solar system. will have orbits that are in the same plane It’s called the Ecliptic Plane, but Pluto’s orbit is tilted 17 degrees from this plane. Observing Pluto will be seen rotating chaotically. Among other planets that orbit in an orderly manner
“Pluto” was discovered on February 18, 1930 by Clyde Tombaugh of Lowell Observatory in Flagstaff, Arizona, and the astronomy community named its member. New solar system with such a name which means “god of death”
This former ninth planet has a diameter of approximately 2,300 kilometers, a distance from the sun of approximately 5,900 million kilometers, and has an elliptical orbit around the sun, which is different from other planets. And it takes 248 years to complete one complete orbit. There are 5 known satellites: Charon, Styx, Nix, Kerberos, and Hydra.
Although Pluto has now been removed from being a planet. But there are still some astronomers who still classify Pluto as a planet. And Pluto is still another interesting star that is suitable for exploration. One of them is the story Caron moon One of the moons that is half as large as Pluto And from the new definition of planets and dwarf planets, these two stars can be considered as binary stars that are dwarf planets in our solar system.
Incidentally, “World April Fools Day” falls on April 1 of every year. On this day, it is a day when people play jokes and lie to each other. But it must be on a basis that does not cause harm to others. And it’s not about loss. This can be seen from various social media worlds. Fake news may be presented today. And it is becoming more popular among people around the world due to the popularity of social media nowadays.
