DWARF PLANET

• Pluto is called a dwarf planet

• A dwarf planet is round and orbits

the sun just like the eight major

planets.

• a dwarf planet does not have

enough gravity to attract all of the

space dust and tiny objects in its

path.

• A dwarf planet also is much smaller

than a planet, but it is not a moon.

PLUTO FACTS

• Pluto is the only dwarf planet to once

have been considered a major planet

• Pluto was reclassified as a dwarf planet in

2006

• American astronomer Percival Lowell first

caught hints of Pluto's existence in 1905

• Its discovery came in 1930 from Clyde

Tombaugh at the Lowell Observatory

• Before it was officially called as

Pluto, it was named as “Planet X”

• Pluto is also called “plutoid”

which means a dwarf planet

farther out the in space than the

planet Neptune.

How it was named?

• Pluto was named

after the Roman

god of the

underworld

• Which Roman god

to name it after

was decided by

Venita Burney, an

11 year old

schoolgirl.

PHYSICAL

CHARACTERISTICS

• Pluto has an estimated diameter less

than one-fifth that of Earth or only

about two-thirds as wide as Earth's

moon

• The planets’ surface conditions

probably consist of a rocky core

surrounded by a mantle of water ice,

with more exotic ices such as methane

and nitrogen frost coating its surface

PHYSICAL

CHARACTERISTICS

• Pluto's orbit is highly eccentric, or far from

circular, which means its distance from the

sun can vary considerably and at times,

Pluto’s orbit will take it within the orbit of

the planet Neptune.

PHYSICAL

CHARACTERISTICS

• Pluto's orbit is highly eccentric, or far

from circular

• Pluto's low gravity, which is a little

more than one-twentieth that of

Earth's, causes this atmosphere to

extend much higher in altitude than

Earth's.

• Pluto's surface is one of the coldest

places in the solar system at roughly

minus 375 degrees F (minus 225

degrees C).

PHYSICAL

CHARACTERISTICS

• When compared with past images, the

Hubble pictures revealed that Pluto

had apparently grown redder over time,

apparently due to seasonal changes.

ORBIT AND ROTATION

• Pluto's highly elliptical orbit can take it

more than 49 times as far out from the

sun as Earth

ATMOSPHERE

• During Pluto’s elliptical when Pluto is

closer to the Sun its surface ice thaws

and forms a thin atmosphere primarily

of nitrogen with a little methane and

carbon monoxide.

• The dominating gas in Pluto's atmosphere

is nitrogen. Carbon monoxide and methane

are also present.

• Its atmosphere resembles Neptune's moon,

Triton, which boasts clouds and winds.

SURFACE OF PLUTO

• Pluto's composition bears a greater

resemblance to the rocky terrestrial

planets than the gas giants that are its

neighbours

• dominated by ices, with some rock

mixed in

• 70 percent rock and 30 percent water

ice.

INSIDE OF PLUTO

• Pluto likely boasts a rocky core.

Surrounded by a mantle of water ice.

• They determined that Pluto's interior

has most likely separated out, with

rock falling to the center while the

lighter ices remained at the exterior.

• Pluto lies in the distant Kuiper Belt,

with similar rock-and-ice bodies

• Pluto contains potassium under its

surface.

PLUTO’S MOONS

•CHARON

•KERBEROS

•NYX

•STYX

•HYDRA

CHARON

• Pluto had a very large moon nearly half

its size - Charon.

• The huge size of Charon sometimes

leads scientists to refer to Pluto and

Charon as a double dwarf planet or

binary system.

• Pluto and Charon are just 12,200 miles

(19,640 km) apart.

• It is widely believed that Pluto and

Charon are a double dwarf planet

because they’re so similar in size

(almost a 1:2 size ratio!)

• the theory suggests Pluto and

Charon share a common center of

gravity

Double Planet Theory

NIX AND HYDRA

• 2005 using Hubble Space Telescope

discovered two other tiny moons of

Pluto, now dubbed Nix and Hydra

• These are two to three times farther

away from Pluto than Charon, and they

are thought to be just 31 to 62 miles

(50 to 100 km) wide.

KERBEROS AND STYX

• Hubble discovered a fourth moon,

Kerberos, in 2011

• estimated to be 8 to 21 miles (13 to 34

km) in diameter

• On July 11, 2012, a fifth moon Styx,

Research & exploration

• NASA's New Horizons mission will be

the first probe to study Pluto, its

moons, and other worlds within the

Kuiper Belt.

• It was launched on January 2006,

making its closest approach to Pluto

on July 2015, and carries some of

the ashes of Pluto's discoverer, Clyde

Tombaugh

Ric Angelo M. Dagdagan

Because we know it’s all

about Pluto

Maliit... na Planet

It’s all about Pluto

Na dating... 9th

Planet

It’s all about Pluto

Na ngayon dwarf planet

It’s all about Pluto... totoo...

it’s Pluto!

Yeah it’s pretty clear, it’s

ain’t no Earth size

Hindi dahil malayo

Pero normal na yan

Yeah got that boom moons

rotate around it.

All the right junk and all the

right places

It’s not Jovian Planet because

it’s not

that big

It lies on Kuiper Belt, it’s so

far far away

Kung may alam ka dito, just

raise it up

Every inch of its detail ay ‘di

pa ganun ka

clear.

Yah may mama she told me

yung inside ay rocky core...

And ang surface ay dominated

nga daw ng yelo...

We know wala din ring ang

Pluto na ibang term – plutoid...

And if that’s what we into

then go head and move
