PLUTOIn 2006 Pluto was demoted to the

status of a dwarf planet.

Naming Pluto An eleven year old English girl named the

newly discovered unknown planet. Venetia Burney thought that ‘Pluto’

would be a good name for the planet which she named after the Roman God of the dark underworld.

Her grandfather thought it was a good idea.

The grandfather sent the idea ‘Pluto’ to the Royal Astronomical Society and it was then accepted.

Why is Pluto a dwarf planet?

THE PROBLEM WITH PLUTO PLUTO IS REALLY SMALL Pluto is a dwarf

planet because it’s too small for it to be a planet.

It is not a planet because it’s not big enough to clear other objects (such as asteroids) out of its path and orbit.

About PlutoRoyal Astronomical Society accepted that planet x could then be called planet Pluto in the 1930’s.

In 2006 Pluto was demoted to a dwarf planet and it was no longer a solar system planet.

Pluto has hardly any atmosphere.

Pluto is just about all ice. Pluto orbits the sun in a

really strange way. This is because as Pluto

moves closer to the Sun ice its surface moves slightly as solids evaporate to gases.

As Pluto moves away from the Sun the gases cool and refreeze.

Pluto’s orbit is more oval shaped and elliptical.

Things that Pluto is missingThe outer planets all have a solid core and methane gas around it.

Pluto does not have that though.

For Pluto to be a planet it will need to orbit a star and orbit the sun in a normal orbit path like the outer planets.

How far away is Pluto to the sun

COMPARING FAR SIGHT HOW IT WOULD BE LOOKING AT THE SUN

Pluto is really far away from the sun.

Pluto is so far away from the sun that the temperature freezing.

When looking at the Sun from Pluto, it is very small because the Sun is so far away.

How Pluto was madeHOW PLUTO WAS MADE FACTS FAST FACTS

It is actually weird how Pluto is made out of these kind of objects.

Inside of Pluto there is water ice and a soft core that’s (iron nickel alloy rock). Its almost like an apple core.

Space craftSPACE CRAFT STUDYING PLUTO The spacecraft New

Horizon launched in 2006 has flown past Pluto this year (2015).

Scientists were excited to see the first close up pictures of Pluto. The space ship called the New Horizon is now flying on into interstellar space.

OUT OF IT. IT WAS ALL ICE.

How Pluto was discoveredHOW PLUTO WAS DISCOVERED FAST FACT FACTS

As of 2008 there are five recognized dwarf planets. Four are: Pluto, Eris, Ceres, and Makemake. It was discovered in 1801 well before Pluto and 45 years before Neptune.

Thermometer facts of Pluto

A THERMOMETER OF PLUTO COMPARED TO OUTER PLANETS FAST FACT

As you can see Pluto is right down the bottom. That means the temperature is really cold on Pluto and there’s a big temperature drop.
