• Pluto is called a dwarf planet
• A dwarf planet is round and orbits
the sun just like the eight major
• a dwarf planet does not have
enough gravity to attract all of the
space dust and tiny objects in its
• A dwarf planet also is much smaller
than a planet, but it is not a moon.
• Pluto is the only dwarf planet to once
have been considered a major planet
• Pluto was reclassified as a dwarf planet in
• 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
How it was named?
• Pluto was named
after the Roman
god of the
• Which Roman god
to name it after
was decided by
Venita Burney, an
11 year old
• Pluto has an estimated diameter less
than one-fifth that of Earth or only
about two-thirds as wide as Earth's
• 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
• 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.
• Pluto's orbit is highly eccentric, or far
• 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
• Pluto's surface is one of the coldest
places in the solar system at roughly
minus 375 degrees F (minus 225
• 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
• 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
• 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
• dominated by ices, with some rock
• 70 percent rock and 30 percent water
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
• 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
• 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
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,

• NASA's New Horizons mission will be
the first probe to study Pluto, its
moons, and other worlds within the
• 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
