Title: Team 1:The Outer Planets and Comets,
1Team 1The Outer Planets and Comets,
- By Greg, Alex, Brittany, Freddy and Cameran
2The four outer planets-Jupiter, Saturn, Uranus,
and Neptune-are much larger and more massive than
Earth, and they dont have solid surfaces.
- Outer planets called gas giants
- Each giant is surrounded by a set of rings-a thin
disk of small particles and ice and rock
3Jupiter
- Jupiter is the largest and most massive planet
- Has a thick atmosphere made up of mainly hydrogen
and helium - Has a great red spot that is made up of a storm
that is larger than Earth and it is similar to a
hurricane - It has a dense core of rock and iron at its
center - It has over 63 moons and four large ones called
Callisto, Io, Europa, Ganymede
4Saturn
- Saturn is the second largest planet in our
universe - It has a thick atmosphere made up of mainly
hydrogen and helium - Its atmosphere also contains clouds and storms
- Saturn has many rings that are made up of chunks
of ice and rocks - Its largest moon is called Titan and it is
larger than the planet Mercury
5Uranus
- Uranus is a gas giant and is four times larger
than Earth - It is much smaller than Jupiter and Saturn
- Uranus has a blue/greenish color because of
trace of methane in its atmosphere - Its surrounded by a group of thin, round rings
like Saturn only much less - Its axis of rotation is tilted at an angle of 90
degrees -
6Neptune
- Neptune is a cold, blue planet and its
atmosphere contains visible clouds - Scientists think that Neptune is slowly
shrinking causing its core to heat up - It has at least 13 moons going around it
- Its largest moon is called Triton which has its
own thin atmosphere
7Pluto
- Pluto has a solid surface and is much smaller
and denser than the other outer planets - It is smaller than Earths moon and is probably
made of rocks and ice - It is so far from the Sun it revolves around it
about every 258 Earth years - Until recently Pluto was considered the 9th
planet in our solar system - Now it is considered a dwarf planet
8Comets
- Comets are loose collections of ice, dust and
small rocky particles - Its orbits are usually very long, narrow
ellipses - Most comets originate from one of two distant
regions of the solar system - They come from the Kuiper Belt of the Oort cloud
- As a comet approaches the sun, it heats up and
some of the gas and dust streams outward forming
a tail

10Inner planetsEarth and Venus
- Earth Earth is unique in our solar system in
having liquid - water at its surface. Earth is 70 water.
- Atmosphere extends more than 100 kilometers
above the surfaces. About 20 is oxygen and
nearly all the rest is nitrogen with small
amounts of other gases such as argon and carbon
dioxide. - Venus Venus takes about 7.5 Earth months to
revolve around the sun and takes 8 months to
rotate on its axis. - Atmosphere Its atmosphere is so thick that
it is always cloudy.
11Mercury and Mars
- Mercury Smallest terrestrial planet and closest
to the sun. Mercury has almost no atmosphere. Its
high temperature causes gas particles to move
very fast. - Mars Marss atmosphere is more than 95 carbon
dioxide. Scientists think that a large amount of
liquid water flowed on Marss surface in the
past. Because it is tilted on its axis it has
seasons just like Earth. -
12Asteroids
- Asteroids are rocky objects that mostly revolve
around the sun in fairly circular orbits between
the orbits of Mars and Jupiter. This region of
the solar system is called the asteroid belt. - There are more than 100,000 asteroids discovered
in the asteroid belt. Some asteroids are so big
they are considered dwarf planets.

- Alyssa Cheshire
- Bev Lincoln
- Tristan Collins
14Satellites
- A Satellite is an object that revolves around
another object in space. - The moon is a natural satellite of Earth.
- A Spacecraft orbiting Earth is an artificial
satellite. - The first artificial satellite was named the
Sputnik, its success caused great alarm to the
United States.
15Meteors
- When a Meteoroid enters Earths atmosphere,
friction with the air creates heat and produces a
streak of light in the sky , this is known as a
Meteor. - If the meteoroid is large enough, it may not
disintegrate completely. - If not completely disintegrated, it can pass
through Earths atmosphere.
16Meteorites
- A meteoroid that passes through the atmosphere
and hits Earths surface. - The crater in Arizona was created by a meteorite.
-
17 Meteoroids
- A Meteoroid is a chunk of rock or dust in space.
- Meteoroids come from comets or asteroids.
- Some form when asteroids collide in space.
- Others form when a comet breaks up and creates a
cloud of dust that continues to move through the
solar system. - When Earth passes through one of there dust
clouds, bits of dust enter Earths atmosphere. - The creators on the moon were formed by
meteoroids.
18Team 4 Black Holes, Dark Energy and Dark Matter

- Yareyci Rivera
- Katherine Gomez
- Joe Hamilton
19Black Holes
- After a large star runs out of fuel, it implodes
causing a super nova. The gravity mass is so
strong that the gas is pulled inward, creating a
black hole. - No light, radio waves, or any other form of
radiation can ever get out of a black hole, so it
is not possible to detect a black hole directly. - You can detect them indirectly.
- Black holes can be millions or even billions
times bigger than the suns initial mass.
20Dark Matter
- It is matter that does not give off
electromagnetic radiation. - Dark matter cannot be seen directly.
- But, its presence can be inferred by observing
the effect of its gravity on visible objects,
such as stars, or on light. - Astronomers are still trying to find out what the
Dark Matter is made out of.
21Dark Energy
- Dark energy is a mysterious force that is causing
the expansion of the universe to accelerate. - Current estimates indicate that most of the
universe is made of dark energy and dark matter. - Less than 5 of the universe is made up of normal
matter.

26Team 5 Space Exploration(History and Future) and
Telescopes.

27History of Space
- A satellite is an object that revolves around
another object in space. - In late 1958, the United States established a
government agency in charge of its space program
called the National Aeronautics and Space
Administration(NASA). - On July 20,1969 Apollo 11 astronaut Neil
Armstrong became the first person to walk on the
moon. - The astronauts collected nearly 400 kilograms of
lunar samples, commonly called moon rocks.
28The Future of Space
- In 2004, the U.S announced a plan to establish a
permanent colony of people on the moon. - Nasa used space shuttles to perform many
important tasks. These included taking satellites
into orbit, repairing damaged satellites , and
carrying astronauts and equipment to and from the
space station.
29Telescopes
- All the colors you see in a telescope is called
visible light. It one of many types of
electromagnetic radiation. - Telescopes are instruments that collect and focus
light and other forms of electromagnetic
radiation. - The two major telescopes are refracting
telescopes and reflecting telescopes.
30The Sun
- Bailey Vaskov, David Zamora, Kelly Doherty, Emily
Threlkel
31The Suns Energy
- The sun accounts for 99.8 percent of the solar
systems total mass. - The sun is a huge ball of ionized gas, or plasma,
thought. - About three quarters of the suns mass is
hydrogen. - About one quarter of the suns mass is helium.
32Nuclear Fusion
- The sun produces energy through nuclear fusion.
- In nuclear fusion two atomic nuclei combine,
forming a larger. More massive nucleus and
releasing energy. - Within the sun, hydrogen atoms join together to
form helium.
33The Suns Interior
- The suns interior consists of the core, the
radiation zone, and the convection zone. - The core is where the suns energy is produced.
- The radiation Zone is region of very tightly
packed gas where energy is transferred mainly in
the form of electromagnetic radiation. - The convection zone is the outer-most layer of
the suns interior.
34The Suns Atmosphere
- The inner layer of the suns atmosphere is called
the photosphere. - The sun does not have a solid surface.
- There are dark spots on the sun called sunspots.
- Sunspots are areas where the sun is cooler.
- The suns interior is about 1.4 million
kilometers. - Sun spots usually occur in huge, reddish loops of
gas called prominences.
35The Formation of the Solar System
- Bailey Vaskov, David Zamora, Dayton Wallace,
Kelly Dohetty, Emily Threlkel
36The Solar Nebula
- About five billion years ago, a giant cloud of
gas and dust collapsed to form a solar nebula - Gravity began to pull solar nebula together, as
the solar nebula shrank and spun faster and
faster. The solar nebula flattened, forming a
rotating disk. Gravity pulled most of the gas
into the center of the disk where the gas
eventually became hot and dense enough where
nuclear fusion to begin.
37Planetesimals
- Planetesimals formed the building blocks of the
planets, the planets grew larger.
38The Planets
- When the Solar System formed the temperature was
very high. - Most gasses escaped the gravity of the planets,
that were forming in this region, as a result the
inner planets are relatively small and rocky. - The planets farther from the sun are much colder.
As these planets in this region grew, their
gravity increased and they were able to capture
much of the hydrogen and helium in space.
39Evidence
- The composition of the inner and outer planets
provides strong evidence for a solar nebula
theory. - Other evidence includes the position of the sun
at the center of the solar system.
