Pluto Day is celebrated every 18 February to mark the discovery of Pluto by Clyde W. Tombaugh in 1930.

Pluto was initially considered similar in mass to Earth, but later studies reduced its estimated mass. The discovery of trans-Neptunian objects, including Eris in 2005, led to debates about Pluto’s planetary status. In 2006, the International Astronomical Union reclassified Pluto as a dwarf planet based on specific criteria, a decision that received mixed reactions from the astronomical community.

The day offers a fun opportunity to make new friends, release stress, and repurpose old pillows. Cities including San Francisco, Hong Kong, Manhattan, Vancouver, Dallas, London, and locations in Australia participate in this global event.
