Why Pluto is Not a Planet Anymore

🌌 Why did Pluto lose its planet status?


🪐 Pluto’s story

  • Pluto was discovered in 1930
  • For many years, it was called the 9th planet
  • In 2006, scientists changed its status

👉 Pluto did not disappear — only its category changed


📏 New rules for being a planet

In 2006, scientists made 3 rules for a planet:

A planet must:
1️⃣ Orbit the Sun
2️⃣ Be round in shape
3️⃣ Clear its path around its orbit


✅ Pluto passes 2 rules…

✔ Orbits the Sun
✔ Is round


❌ Pluto fails the 3rd rule

❗ “Clear its path” means:

  • A planet should be the big boss in its orbit
  • It should push away or control other nearby objects

🧠 Pluto shares its space with many icy objects in the Kuiper Belt

So Pluto is not strong enough to clear its orbit.


🧊 What is Pluto now?

Pluto is called a Dwarf Planet

Other dwarf planets:

  • Ceres
  • Eris
  • Haumea
  • Makemake

🌟 Fun facts for kids

  • Pluto is smaller than Earth’s Moon
  • It is very cold ❄️
  • A year on Pluto = 248 Earth years
  • Pluto has 5 moons

🧠 Easy way to remember

Planet = clears its path
Pluto = shares its path


💬 Important note

Many people still love Pluto ❤️
It is special, just not a planet by the new rules.
