What are the similarities and differences between the inner and outer planets of the solar system?
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).
How are planets similar and 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.
What is a similarity between all planets?
The planets in our solar system have similar interiors composed of a core and a mantle. Terrestrial planets also have a crust or a solid outer shell. The core of terrestrial planets consists mainly of iron, wrapped in a silicate mantle.
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.
How are the inner planets alike?
All of the inner planets are solid, dense, rocky planets. The inner planets either do not have moons or have just one (Earth) or two (Mars). None of the inner planets have rings. Compared to the outer planets, the inner planets have shorter orbits around the Sun, but all the inner planets spin more slowly.
What are three similarities among the inner planets?
Three Major Characteristics of the Inner Planets
- Terrestrial Planet Formation. Astronomers theorize that the very early solar system formed as a ring of materials surrounding the sun. …
- Size Range. …
- Rocky Surface. …
- Iron Core.

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 qualities do the inner planets have in common?
All of the inner planets are solid, dense, rocky planets. The inner planets either do not have moons or have just one (Earth) or two (Mars). None of the inner planets have rings. Compared to the outer planets, the inner planets have shorter orbits around the Sun, but all the inner planets spin more slowly.
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.
Do inner planets have moons?
Of the terrestrial (rocky) planets of the inner solar system, neither Mercury nor Venus have any moons at all, Earth has one and Mars has its two small moons. In the outer solar system, the gas giants Jupiter and Saturn and the ice giants Uranus and Neptune have dozens of moons.
What common characteristics do the inner planets share?
All of the inner planets are solid, dense, rocky planets. The inner planets either do not have moons or have just one (Earth) or two (Mars). None of the inner planets have rings. Compared to the outer planets, the inner planets have shorter orbits around the Sun, but all the inner planets spin more slowly.
What do the first 4 planets have in common?
The four inner planets — Mercury, Venus, Earth and Mars — share several features in common. Astronomers call them the “terrestrial planets” because they have solid, rocky surfaces roughly similar to desert and mountainous areas on the earth.
What characteristics do all the inner planets have in common?
All of the inner planets are solid, dense, rocky planets. The inner planets either do not have moons or have just one (Earth) or two (Mars). None of the inner planets have rings. Compared to the outer planets, the inner planets have shorter orbits around the Sun, but all the inner planets spin more slowly.
What do the four terrestrial planets have in common?
The four terrestrial planets contain similar rocks and metals. Their cores differ somewhat in state (molten, partially molten or solid), but iron is a major component in all four. These planets are small relative to the gas giants, their closely packed elements making for rocky planets with high densities.
What are 3 things the outer planets have in common?
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.
What does outer space smell like?
A succession of astronauts have described the smell as '… a rather pleasant metallic sensation … (like) … sweet-smelling welding fumes', 'burning metal', 'a distinct odour of ozone, an acrid smell', 'walnuts and brake pads', 'gunpowder' and even 'burnt almond cookie'.
Does space ever end?
No, they don't believe there's an end to space. However, we can only see a certain volume of all that's out there. Since the universe is 13.8 billion years old, light from a galaxy more than 13.8 billion light-years away hasn't had time to reach us yet, so we have no way of knowing such a galaxy exists.
What are the similarities of the inner planets?
The four planets closest to the Sun—Mercury, Venus, Earth, and Mars—are the inner planets or terrestrial planet (Figure below). They are similar to Earth. All are solid, dense, and rocky. None of the inner planets has rings.
What planet has 81 moons?
Jupiter Jupiter has more natural satellites than any other planet in the solar system. By the latest count, there are 81 Jovian moons, the last two being officially recognized in June 2017.
Which characteristics are shared by all planets?
| Terrestrial Planets | Jovian Planets |
|---|---|
| The separation between the planets is small (Mars is 1.5 A.U. from the Sun). | The separation between the planets is large. (Jupiter is 5.2 A.U. from the Sun, the distance between Jupiter's orbit and Saturn's is 4.3 A.U.) |
| No rings | Have rings |
| Two moons or less | More than ten moons |
| Small | Large |
What are four common features of the outer planets?
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.
Do inner planets have rings?
1) The “inner planets” (Mercury, Venus, Earth, Mars) don't have rings and all of the “outer planets” (Jupiter, Saturn, Uranus, and Neptune) do. 2) The outer planets are much more massive than the inner planets.
Can u fart in space?
On Earth, farts are typically no big deal — smelly, harmless, and they quickly dissipate. But if you're an astronaut, every fart is a ticking time bomb. The gases in farts are flammable, which can quickly become a problem in a tiny pressurized capsule in the middle of space where your fart gases have no where to go.
Do you age in space?
In space, people usually experience environmental stressors like microgravity, cosmic radiation, and social isolation, which can all impact aging. Studies on long-term space travel often measure aging biomarkers such as telomere length and heartbeat rates, not epigenetic aging.
Is there color in space?
Because space is a near-perfect vacuum — meaning it has exceedingly few particles — there's virtually nothing in the space between stars and planets to scatter light to our eyes. And with no light reaching the eyes, they see black.
What is inside a black hole?
The singularity at the center of a black hole is the ultimate no man's land: a place where matter is compressed down to an infinitely tiny point, and all conceptions of time and space completely break down. And it doesn't really exist.
Does Earth have 3 moons?
TWC India. A group of Hungarian scientists has confirmed a long-standing astronomical speculation: the Earth has three natural satellites or moons, not one.
What was Uranus named after?
Greek god of the sky It was German astronomer Johann Bode who recommended the name Uranus, a Latinized version of the Greek god of the sky, Ouranos; however, the name Uranus didn't gain full acceptance until the mid-1800s.

What characteristics do you think the outer planets have in common?
All of the outer planets have numerous moons. They all also have planetary rings, composed of dust and other small particles that encircle the planet in a thin plane.
