Astronomers Are No Space Cadets, It Takes A Lot To Name New Moons

Pluto is a dwarf planet. Pluto was discovered in 1930 by the American scientist Clyde Duboumbog. This dwarf planet also revolves around the sun like other planets. But it is very small in size. It was discovered in the same month i.e. February 18. This dwarf planet does not meet the third condition of being a planet, because its orbit collides with the orbit of Neptoon during the orbit of the Sun. It was previously considered a planet, but in 2006, scientists dropped it out of the planets. You will be surprised to know that when a suggestion was asked to name this planet, a girl studying in the 11th named it Pluto.

Only one space mission in 90 years
In Rome, the god of darkness is called Pluto and there is always darkness on this planet, so it should be named Pluto. It takes 248 years for Pluto to make one round of the sun. Just as we have 24 hours a day here, in the same way it is equal to 24 hours 153.36 hours in plots. That is, here it takes about 6 days a day and night. The planet Pluto is so small that it can have no effect on the orbit of another planet. The planet Pluto was discovered by a mistake by scientists when they were calculating based on the speeds of Uranus and Neptune. Scientist Clyde Tombaugh carefully studied the sky and discovered the planet Pluto on 18 February 1930. So far, only one spacecraft, New Horizons, has arrived on the planet Pluto which was launched on 19 January 2006. On 14 July 2015 it passed near Pluto. It took many pictures of the planet Pluto and calculated it. Looking at the photos, it turns out that there are many icy mountains on Pluto. At the same time the size of Pluto is larger than it was anticipated. So far five planets (satellite) of the planet Pluto – Styx or P5, Kerboros or P4, Hyrda and Nix, Charan have been discovered.

3 times more water than Earth’s oceans
Pluto is smaller than the solar system’s 7 satellites. It is 65% of the diameter of the Earth’s satellite – the Moon and only 18% of the mass. 1 year of the planet Pluto (the period of the Sun’s orbit) is equal to 246.04 years of the Earth. Pluto’s distance from the Sun is 587 million 40 million kilometers. Its diameter is 2372 kilometers. Pluto has a mass of 13050 billion kg. On 24 August 2006, Pluto was removed from the class of planets by the International Astronomy Organization (IAU) and given the status of “dwarf planet”. This organization says that Pluto does not orbit the Sun on the same path as other planets. Due to this, the status of the planet has been withdrawn from it. According to astronomers, planets are those that orbit the Sun in its fixed orbit and approve other satellites in its orbit. However, in 2019, it was again added to the list of planets. It takes 5 and a half hours for sunlight to reach Pluto. If your weight on Earth is 45 kg, then your weight on Pluto will be 3 kg. One third of Pluto is water. This water is stored as ice. This is 3 times more than the oceans found on Earth. The remaining two-thirds of Pluto are rocks. It has many mountain ranges and deep pits. The sky looks very dark with Pluto. You can also see stars in the day.

Pluto’s icy mountain named Tenzing Norgay
After NASA’s New Horizons probes embarked on a space mission six years ago, NASA and the IAU formulated a naming plan that focused on deep space depths and voyages of discovery. He agreed that the mountains found on any planet would be named after historical explorers. At the same time, the black spots and grounds found on its moon will be named after space missions. Due to this, the 20 thousand feet high snow mountain found on Pluto is named after the Nepali climber Tenzing Norgay. Similarly, the black spots found on its moon are named after the character ‘Mordor’ in the Hollywood film Lord of the Rings. Once the name is selected it cannot be changed.

This is how the names of planets, satellites and moons
Why were the new planets, asteroids, meteorites and stars and galaxies discovered by astronomers in space the same name as we know them today? Indeed, the International Astronomical Union (IAU) plays an official role in naming the newly discovered celestial bodies in addition to the planets and satellites of the Solar System since 1919. Astronomers also closely follow the Union’s guidelines. The naming is done according to the stated guidelines of the association. For example, if a lunar astronomer has discovered a new peak on the moon, it will be named after a geologist. Similarly, if a new topography is discovered on Saturn’s satellite Titan, it will be named on the basis of fantasy or science fiction. Similarly, if a new moon is discovered on the planet Brahaspati, its name should be based on fire, volcano, or the 18th century Italian writer-poet Dante’s poem Inferno.

Strict rules made to avoid confusion
The name of the newly discovered moons of Brahaspati must come from one of the characters mentioned in Greek or Roman mythology. Also the name must be 16 characters or less. Apart from this, it has not been used for any political, military or religious activities in offending, business and past 100 years. Also, the name should not be similar to the name of a living person and any moon or asteroid present in it. The most important thing is that if the moon is moving in the rotation direction of its respective planet then its name should end on A and if it rotates in the opposite direction of the planet then in this case the name should end on E. Astronomer Scott Shepherd says that the number of mythological characters that meet the criteria of the International Astronomical Union is limited. According to him the names ending in E word are out of fashion at present. Astronomer Gareth Williams of the Harvard Smithsonian Center for Astrophysics states that these strict rules are designed to avoid any confusion during intensive study of the universe. The study of the solar system was fraught with confusion and disturbances until the Sangh came into existence in the early 20th century. Often, international controversy and political tussle over the naming of new planets and stars also begin.
