Since 2006 Pluto has ceased to be considered a planet. They said he was too small for that. But now many astronomers claim that disassembling it was a gross mistake. And explain why. In the opening photo, Pluto, photographed by the New Horizons spacecraft. Their colors are interpreted by computer.
Pluto has mountains and even an atmosphere, but it is not officially considered a planet. NASA
Astrologers died laughing when a group of powerful astronomers decided in 2006 to lower Pluto by withdrawing it from the club of the nine planets of the Solar System and relegating it to the less prestigious category of "dwarf planet." Pluto, for astrology, is a planet of first greatness, and a very important presence in horoscopes. Well, astronomers and astrologers have never slept in the same bed ... But the truth is that even among astronomers, who knowingly want the study of the stars and their movements in the heavens to be purely Cartesian science, the end of Pluto as a planet did not please anything, either out of habit or affective reasons, or because they had already decorated the names of the nine planets, from Mercury, closest to the Sun, to Pluto, the farthest ... Now, to the many who dispute the relegation , also joined the astronomers of the Universiy of Central Florida: ...
The definition of UAI (the entity that expelled Pluto from the club in 2006) wants a planet, to be considered as such, to meet three requirements: to be massive enough for its gravity to give it a rounded shape; orbiting around the Sun; and (attention!) to dominate the own orbit, that is to have emptied its "zone" of the Solar System of other celestial bodies.
Pluto has 5 satellites. The largest of them, Charon (pictured), was probably shaped by an impact of Pluto itself with one of the many objects transiting in its orbital zone. NASA
The rest is talk: Pluto, sharing its orbit with so many other small Transnetunian objects, has lost its planet status. The decision was immediately criticized, first by astrologers and others in love, but soon several astronomers rebelled against it, and now also the important team of scholars at the Florida Space Institute, led by Philip Metzger. The protests of this group are based on the historical bases of the requirement of orbital dominance, and also on a historical precedent, similar to the current one.
