The outer planets are made of hydrogen and helium so they are called gas giants.Sep 19 2018

What are the differences between inner planets and outer planets?

The inner planets are closer to the Sun and are smaller and rockier. The outer planets are further away larger and made up mostly of gas. The inner planets (in order of distance from the sun closest to furthest) are Mercury Venus Earth and Mars.

What are two major differences between the inner planets and the outer planets?

The inner planets are made up of rock and metal and are therefore solid. These planets move slowly as they are considered to be heavy. They have an average diameter of about 13000 km as they are small planets. On the other hand the outer planets are said to be made of gases and they are not really solid.

What are 5 differences between inner and outer planets?

The four inner planets have slower orbits slower spin no rings and they are made of rock and metal. The four outer planets have faster orbits and spins a composition of gases and liquids numerous moons and rings. The outer planets are made of hydrogen and helium so they are called gas giants.

How are the inner planets similar?

The Inner Planets

They are similar to Earth. All are solid dense and rocky. None of the inner planets has rings. Compared to the outer planets the inner planets are small.

Why do the inner and outer planets have different compositions?

The outer planets are much larger than the inner planets. Because of their large mass and cooler temperature they have a very different composition they are mostly made of light elements with extended atmospheres in a gaseous form. Outer planets exist in much bigger systems than inner planets.

How are Jupiter and Saturn similar?

Saturn and Jupiter are both gas giants. They are both the largest planets in the Solar System despite Jupiter being twice the mass of Saturn. They are both made up of similar gases and their structure is very similar. They are both comprised of mainly hydrogen and part helium.

What is the difference between inner and outer space?

In popular psychology inner space refers to thoughts imagery dreams attitudes and feelings while outer space refers to the external environment.

Why are inner planets smaller than outer planets?

The temperature of the early solar system explains why the inner planets are rocky and the outer ones are gaseous. … The inner planets are much smaller than the outer planets and because of this have relatively low gravity and were not able to attract large amounts of gas to their atmospheres.

Why are planets different from each other?

why are other planets different than earth? A: Planets have different properties because they are different distances away from the sun are different sizes and are made up of different stuff from the earth. Very tiny planets do not have enough gravitational field to keep much of an atmosphere in.

How are the compositions of the planets different?

Differentiation is the process by which gravity helps separate a planet’s interior into layers of different compositions and densities. The heavier metals sink to form a core while the lightest minerals float to the surface to form a crust. Later when the planet cools this layered structure is preserved.

What are the similarities and the differences between the Sun and Jupiter?

Jupiter and the sun are both very similar in their overall composition as they are both made up almost entirely of hydrogen and helium. The sun has a core that is so hot that it causes hydrogen to separate into individual electrons and protons Jupiter’s core is made of liquid metallic hydrogen.

Which characteristic is common to the four outer planets?

The four outer planets are all gas giants made primarily of hydrogen and helium. They have thick gaseous outer layers and liquid interiors. The outer planets have numerous moons as well as planetary rings.

How long is 1 hour in space?

Answer: That number times 1 hour is 0.0026 seconds. So a person at that deep space location would have a clock that would run for one hour while that person calculated that our clock ran for 59 minutes 59.9974 seconds.

Is there such thing as inner space?

“Outer space” can mean anything not on Earth – the ionosphere Earth-Luna space interstellar space intergalactic space as long as it’s not on Earth. “Inner space” can refer to anything – inside you inside your living room inside your house.

Does space have an end?

Scientists now consider it unlikely the universe has an end – a region where the galaxies stop or where there would be a barrier of some kind marking the end of space.

What is different about the planets?

The key difference between a planet and a dwarf planet is the kinds of objects that share its orbit around the Sun. Pluto for example has not cleared its orbit of similar objects while Earth or Jupiter have no similarly-sized worlds on the same path around the Sun.

Are all the other planets similar to Earth or are they very different?

The mediocrity principle suggests that planets like Earth should be common in the Universe while the Rare Earth hypothesis suggests that they are extremely rare. The thousands of exoplanetary star systems discovered so far are profoundly different from the Solar system supporting the Rare Earth Hypothesis.

What is the composition of the inner and outer planets?

The small inner planets (Mercury Venus Earth and Mars) are composed mostly of silicate rocks and metals the outer planets (Jupiter Saturn Uranus and Neptune) are much larger consist mostly of gaseous hydrogen and helium and ice and have large systems of icy moons.

What is similar or different about the planets atmosphere compositions or features?

The terrestrial planets are rich in heavier gases and gaseous compounds such as carbon dioxide nitrogen oxygen ozone and argon. In contrast the gas giant atmospheres are composed mostly of hydrogen and helium. The atmospheres of at least the inner planets has evolved since they formed.

How do the inner terrestrial planets including Earth differ from outer jovian planets in terms of size composition and density?

The cores of of terrestrial planets are mainly dense iron with silicate and although jovian planets have denser cores terrestrial planets overall are more dense. … Jovian planets also have gaseous atmospheres with the main gases being hydrogen and helium.

What are some differences between the Sun and planets?

A sun or star is a large body consisting of mainly Hydrogen and helium. It is massive enough for fusion reactions to take place in its core. … A planet is any body which orbits a star and has cleared its orbit of other bodies.

What are differences between stars and planets?

It is important to understand the clear distinctions between a star and a planet a star is a body that possesses a light which causes it to reflect the light on its own.
Difference between Stars and Planets
Stars have a unique effect of twinkling in the sky. Planets do not exhibit the twinkling effect unlike stars

Which move faster Saturn’s inner or outer rings?

The inner parts of the rings move around Saturn faster than the outer parts all in accordance with Kepler’s third law for small objects revolving about a massive larger one.

Does Earth have 3 moons?

After more than half a century of speculation it has now been confirmed that Earth has two dust ‘moons’ orbiting it which are nine times wider than our planet. Scientists discovered two extra moons of Earth apart from the one we have known for so long. Earth doesn’t have just one moon it has three.

How many rings does Earth have?

If you’re talking about majestic ice rings like we see around Saturn Uranus or Jupiter then no Earth doesn’t have rings and probably never did. If there was any ring of dust orbiting the planet we’d see it.

Can moons have moons?

Yes in theory moons can have moons. The region of space around a satellite where a sub-satellite can exist is called the Hill sphere. Outside the Hill sphere a sub-satellite would be lost from its orbit about the satellite. An easy example is the Sun-Earth-Moon system.

What are the inner planets?

The planets Mercury Venus Earth and Mars are called terrestrial because they have a compact rocky surface like Earth’s terra firma. The terrestrial planets are the four innermost planets in the solar system.

Which planet is an inner planet and which one is an outer planet explain your answer?

the inner planets of the solar system are mercury venus earth and mars. whereas the outer planets are jupiter saturn uranus and neptune.. they differ from each other according to their size. the inner planets are before the asteroids and the outer planets are after the asteroid belt..

How are Mars and Saturn similar?

The planets Mars and Saturn don’t have a lot in common. Mars is small dense and rocky. … So while Saturn is many times larger than Mars it’s the “fluffiest” planet in the solar system. One possible similarity though is rings.

Do you age slower in space?

We all measure our experience in space-time differently. That’s because space-time isn’t flat — it’s curved and it can be warped by matter and energy. … And for astronauts on the International Space Station that means they get to age just a tiny bit slower than people on Earth. That’s because of time-dilation effects.

Is an hour in space 7 years on Earth?

The first planet they land on is close to a supermassive black hole dubbed Gargantuan whose gravitational pull causes massive waves on the planet that toss their spacecraft about. Its proximity to the black hole also causes an extreme time dilation where one hour on the distant planet equals 7 years on Earth.

Has anyone died in space?

A total of 18 people have lost their lives either while in space or in preparation for a space mission in four separate incidents. Given the risks involved in space flight this number is surprisingly low. … The remaining four fatalities during spaceflight were all cosmonauts from the Soviet Union.
