Scientists are launching a campaign to bring Pluto back to the planetary level


A team of scientists seeking to bring Pluto back to the planetary class on Tuesday (March 21) began expanding the astronomical classifications that led 10 years ago to change the orbital classification to a “dwarf planet.”

Six scientists from US institutions said Pluto deserved to be a complete planet and about 110 other astronomical bodies in the solar system, including the moon orbiting the earth.

In a paper presented at an international scientific conference in Texas, the researchers said geological properties, including shape and surface, should be the criteria that define the definition.

In 2006, the International Astronomical Union (IAU), in the context of its suffering on how to classify a newly discovered glacial body behind Pluto, defined a planet on the basis of properties, including the ability to displace other objects.

Pluto and its new finder were then reclassified as dwarf planets with Ceres, the largest object in the asteroid belt between Mars and Jupiter. The decision left the solar system with only eight planets.
