Pluto Day is celebrated on the 13th of March every year to honor one of the most mysterious objects in space, Pluto.
Pluto, despite being reclassified in 2006 as a dwarf world, remains one of the objects that are most discussed and searched for in astronomy.
This guide will explain what Pluto Day is. It will also tell you why Pluto was reclassified. What scientists have discovered and why Pluto matters today are all explained.
What Is Pluto Day?
Pluto Day is a celebration of the discovery of Pluto by Clyde Tombaugh on March 13, 3030.
Space enthusiasts, science educators, and students interested in learning about planets and dwarf planets as well as the outer solar systems are all fans of this day.
Is Pluto Still a Planet?
The International Astronomical Union has officially classified Pluto as a dwarf world.
Scientists redefined the definition of a planet in 2006 and Pluto did not meet all criteria. Pluto is still important scientifically because it’s part of the Kuiper Belt, a region with icy objects that extends beyond Neptune and helps scientists understand how the solar system was formed.
What Did Scientists Discover About Pluto?
The New Horizons mission of NASA in 2015 revealed Pluto to be more complex than scientists had thought.
Major discoveries include:
- Mountain ranges made from frozen water ice
- Tombaugh Regio is a heart-shaped glacier
- The atmosphere is thin and covered with haze.
- Geology active and changing seasons
These discoveries showed that Pluto is not a frozen planet in space, but an active world.
Why Pluto Still Matters Today
Pluto is helping scientists to understand the Kuiper Belt, and early formation of our solar system.
Pluto, despite its small size, provides important clues to distant worlds on the outer edge of our solar systems. Pluto is also culturally significant because it was taught to many as the ninth planet.
How to Celebrate Pluto Day
Pluto Day can be celebrated in many ways.
- Pluto Images from New Horizons
- Pluto Day facts to share on social media
- Teach children about dwarf planets
- Solar system documentarys
- Visit a science museum or planetarium
