Why are the outer planets so different?
The four inner planets have shorter orbits, slower spin, no rings, and they are made of rock and metal. The four outer planets have longer 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 planets different from each other?
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.
How are the planets alike and how are they different?
Planets may be very different, but they also have many things in common. Inner planets (Mercury, Mars, Venus, and Earth) are all close to the sun, so they are warmer than the outer planets. They are all made up of rock, and different minerals like meld spars. The inner planets are all small, no moons and no rings.
How are the outer planets different from the inner planets provide at least two differences?
Inner planets have fewer moons, small, silicate surface, nickel-iron core, higher density and rotate more slowly compared to outer planets. Outer planets have a greater number of moons, no solid part; rotate faster, have a lower density as well as rings in some cases (Jupiter and Saturn).
Why are the inner and outer planets so different?
The temperature of the early solar system explains why the inner planets are rocky and the outer ones are gaseous. As the gases coalesced to form a protosun, the temperature in the solar system rose. In the inner solar system temperatures were as high as 2000 K, while in the outer solar system it was as cool as 50 K.
What are the features of the outer planets?
The four outer planets—Jupiter, Saturn, Uranus, and Neptune—are all gas giants made primarily of hydrogen and helium. They have thick gaseous outer layers and liquid interiors. All of the outer planets have numerous moons, as well as planetary rings made of dust and other particles.
Which planet is most different from the other planets?
Venus rotates very slowly, taking 243 days to complete one turn. It is named for the Roman goddess of love. Earth is a little more than 12,000 kilometers in diameter. It differs from the other planets because it has liquid water on its surface, maintains life, and has active plate movement.
How are the outer planets similar?
How are the outer planets similar to each other? All outer planets are enormous and are spaced far away from one another. They are mostly composed of gases with small rocky cores. They all have intense environments with a lot of wind, storms, and extreme temperatures.
What are the characteristics of outer planets?
The four outer planets have longer 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.
What is the difference between the inner and outer planet in the solar system?
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 is the difference between inner space and outer space?
Abstract. In popular psychology, inner space refers to thoughts, imagery, dreams, attitudes, and feelings, while outer space refers to the external environment.
Why are they called the outer planets?
Because they are much larger than Earth and the other inner planets, and because they are made primarily of gases and liquids rather than solid matter, the outer planets are also called gas giants.
Why are the outer planets made of gas?
These planets were more massive than the inner planets and were able to attract large amounts of hydrogen and helium, which is why they are composed mainly of hydrogen and helium, the most abundant elements in the solar system, and in the universe.
What are the characteristics of the planet Earth that make it different from all other planets?
It differs from the other planets because it has liquid water on its surface, maintains life, and has active plate movement. It rotates on its axis every 24 hours (a day) and revolves around the Sun every 365 days (a year). The Earth has one moon.
What are three ways that Earth is different from other planets?
Earth is one special planet. It has liquid water, plate tectonics, and an atmosphere that shelters it from the worst of the sun's rays. But many scientists agree our planet's most special feature might just be us.
What is the common characteristic among the outer planets?
What do the outer planets have in common? All of the four outer planets contain rings, have gaseous and icy surfaces, have many moons around them, and are farthest away from the Sun.
What are outer planets made of?
) In contrast, the four outer planets, also called the Jovian, or giant, planets—Jupiter, Saturn, Uranus, and Neptune—are large objects with densities less than 2 grams per cubic cm; they are composed primarily of hydrogen and helium (Jupiter and Saturn) or of ice, rock, hydrogen, and helium (Uranus and Neptune).…
Are outer planets hot or cold?
The Outer Planets The outer solar system is far colder than the inner solar system. The four planets that orbit the Sun in this region are far colder than the four inner worlds. Jupiter is the closest gas giant to the Sun and is thus the warmest planet in the outer solar system.
Do all the outer planets have rings?
SUMMARY: All four jovian planets are surrounded by a set of rings. These rings are made up of rock, ice, and dust particles that range in size from microscopically small to the size of a house.
What is the difference between outer space?
Space means the whole universe including the earth and outer space means all space excluding earth.
How cold is outer space?
about minus 455 degrees Fahrenheit Hot things move quickly, cold things very slowly. If atoms come to a complete stop, they are at absolute zero. Space is just above that, at an average temperature of 2.7 Kelvin (about minus 455 degrees Fahrenheit). But space is mostly full of, well, empty space.
How would you describe the outer planets?
Lesson Summary. The four outer planets — Jupiter, Saturn, Uranus, and Neptune — are all gas giants made mostly of hydrogen and helium. Their thick outer layers are gases and have liquid interiors. All of the outer planets have lots of moons, as well as planetary rings made of dust and other particles.
What are the outer planets and their characteristics?
) In contrast, the four outer planets, also called the Jovian, or giant, planets—Jupiter, Saturn, Uranus, and Neptune—are large objects with densities less than 2 grams per cubic cm; they are composed primarily of hydrogen and helium (Jupiter and Saturn) or of ice, rock, hydrogen, and helium (Uranus and Neptune).…
Why are outer planets bigger?
Water is one of the most common chemical compounds, and its ice form accretes much more easily. This encouraged the outer planets to grow massive. The larger volume of space and lower gravity of the Sun in the giant-planet region allowed Jupiter, Saturn, Uranus, and Neptune to form like solar systems in miniature.
What do you think are the characteristics of the planet Earth that make it different from Mercury?
While both are terrestrial in nature, Mercury is significantly smaller and less massive than Earth, though it has a similar density. Mercury's composition is also much more metallic than that of Earth, and its 3:2 orbital resonance results in a single day being twice as long as a year.
How is the Earth different from other planets Short answer?
Perhaps the most strikingly unique feature of Earth is its vast oceans, which cover 70% of the planet's surface. Earth is the only world in our solar system with liquid water at its surface today. Scientists believe that Mars and Venus may have long ago had oceans, but these are long gone.
What are two facts about how Earth is different from other planets?
Earth has the largest known solid surface. The outer planets are fluid to the core and the inner ones are smaller. Earth has a predominantly nitrogen atmosphere. The gas in outer planets is mostly hydrogen, and Venus and Mars have mostly carbon dioxide in their atmospheres.
Which of the outer planets is most like Earth How?
Venus and Mars are the most like Earth, but in different ways. In terms of size, average density, mass, and surface gravity, Venus is very similar to Earth. But Mars is the planet that is most similar to Earth in other ways.
What do you know about outer planets?
The outer planets are gas giants Jupiter and Saturn and ice giants Uranus and Neptune. Beyond Neptune, a newer class of smaller worlds called dwarf planets reign, including longtime favorite Pluto. Thousands more planets have been discovered beyond our solar system.
What is Earth’s twin planet?
Venus Venus is often called "Earth's twin" because they're similar in size and structure, but Venus has extreme surface heat and a dense, toxic atmosphere.
