JACAYLA’S POST

There was a shift in the classification of objects in our solar system occurred, initially designating nine as planets. However, this changed primarily due to the reevaluation of Pluto's planetary status. In 2006, the International Astronomical Union (IAU) established refined criteria for planetary classification, demanding that a celestial body clears its orbit of other debris. Unfortunately, Pluto did not meet this criterion, leading to its reclassification as a "dwarf planet." This decision was significant in altering the count of recognized planets from nine to eight. The reclassification sparked scientific debates and public discussions, challenging longstanding perceptions of our solar system. This reevaluation highlighted the dynamic nature of scientific understanding and the continuous refinement of our knowledge about celestial bodies.

I would love to hear others thoughts on it, do you think Pluto should be considered as a planet? 

MADISON’S POST

Pluto was considered the ninth planet, but in 2006 International Astronomical Union created a new definition of a planet, and Pluto was no longer considered a planet. A planet was known as a large object within the solar system. Now a planet is defined as planets are celestial objects large enough to be made rounded by their gravitational orbit around the sun and to have moved neighbors away by debris and planetary objects. Pluto fits all of the needs except being Pluto is not large enough to exert its orbital dominance and clear their neighbors out of the way. Pluto is now called a "dwarf planet".
