35+ Fun Facts about Pluto for Kids!

Pluto is the most well known dwarf planet

It was initially classified as a planet until it lost the title in 2006

It was discovered in 1930 by Clyde Tombaugh, a research assistant

Pluto is the 9th largest object to orbit the Sun

Pluto is named after the Roman god of the underworld, originally given by an 11 year-old girl

Pluto has a diameter of 1,474 miles (2377 kilometers)

The average temperature is -387 degrees Fahrenheit (-233 degrees Celsius)

The lowest recorded temperature was -400 degrees Fahrenheit (-204 degrees Celsius)

Pluto’s highest ever temperature was -360 degrees Fahrenheit (-218 degrees Celsius)

It is, on average, 3.7 billion miles away from the sun

It orbits in the opposite direction as Earth

Pluto is smaller than the moon

The country of Russia is about as big as Pluto’s surface area

On Pluto, 100 pounds turns into 7 pounds! It’s gravity is super weak

Pluto’s surface has mountains, canyons, and dunes

It takes about 248 years for Pluto to orbit the Sun

Since its discovery, Pluto has yet to make an orbit around the sun

One day on Pluto is a little over 6 Earth days

Pluto has a very thin atmosphere primarily made of nitrogen, methane, and carbon monoxide

It’s atmosphere creates a blue sky during the day

The farther Pluto gets from the sun, the more its atmosphere has a chance of collapsing

Pluto has 5 moons

They are Charon, Styx, Nix, Kerberos, and Hydra

Charon is the largest of the 5, it is half the size of pluto

Pluto and Charon’s orbital periods are synced, so they always face each other in the same way

This causes them to wobble in their orbit

Charon is sometimes considered a dwarf planet as well

Styx, Nix, Hydra, and Kerberos are a lot smaller than Charon and were all recently discovered

So far there has only been one mission to Pluto

In 2015, NASA’s new horizons spacecraft arrived at Pluto to take pictures of the planet

The most interesting finding of this mission was a heart-shaped region known as “Sputnik Planitia”

It took about 10 years for the New Horizon spacecraft to reach Pluto

It got within 8,000 miles (12,900 kilometers) of Pluto’s surface

After the flyby, the spacecraft continuously transmitted data back to Earth for over a year

The New Horizon spacecraft also recorded data from the Kuiper Belt, the region at the edge of our solar system

As the New Horizon spacecraft launched from Earth, it broke the record for fastest launch ever recorded

As Pluto orbits the sun, it leaves behind a tail of ice, similar to a comet

Pluto is not considered a planet. When it was first discovered, it was the 9th planet in the solar system. Now, it has lost that title and is the most famous dwarf planet. 

Why is Pluto not a planet?

Pluto lost its planet title because it didn’t meet all the criteria. Size is not the issue, in fact Pluto passed every criteria except for one. That is, it hasn’t cleared its region of neighboring objects. Basically, Pluto has too much stuff around it and if it were a planet, these objects would have crashed into its surface.

In August of 2006, the International Astronomical Union stripped Pluto of its title of planet and it became a dwarf planet.

How many moons does Pluto have?

Pluto has 5 moons. They are Charon, Styx, Nix, Kerberos, and Hydra. Charon is the largest of the 5, being almost half the size of Pluto itself. Because Charon is so big, it and Pluto are sometimes called a dwarf planet pair. Another interesting fact is that Charon and Pluto are “locked” in each other’s orbit. This means they always face each other in the same direction.

How big is Pluto?

Pluto is the largest dwarf planet, meaning that it is one of the largest objects in the entire solar system. Pluto has a diameter of nearly 1500 miles (2400 kilometers).

What color is Pluto?

Pluto is unique in the sense that its surface/atmosphere have many different colors. Its surface is white, tan, and brownish-red. From afar, it looks like a gray planet with a brownish hue to it.

When was Pluto discovered?

In 1930, a young research assistant named Clyde Tombaugh discovered Pluto. Shortly thereafter it got its name from an 11 year old girl. 

How far is Earth from Pluto?

Pluto is extremely far away. In fact, it is one of the farthest known objects from Earth. On average, Pluto is about 3.1 billion miles (5 billion kilometers) away.
