The two inner planets most alike in size mass and density are?

Venus and Earth


What are some similarities of the inner and outer planets?

Inner and outer planets have some things that are in common but there mostly way different. For instants they both orbit the sun. On the other hand the outer planets are made mostly by gas, that's why they are called the gas giants. The inner planets are mostly made by rock and dust. The inner planets are called Terrestrial planets and the outer planets are called Jovian planets. The inner planets are closer to the sun, have more density, they have less moons, there about the size of Earth, and they rotate slowly. The outer planets (Jovian Planets) are farther from the sun, they have less density, they have more moons, they are large, about the size of Jupiter, they rotate rapidly, and they have more mass. These planets are alike because they both orbit the sun.


The most obvious difference between the terrestrial and the jovian planets is?

The size. The gaseous Jovian planets are far larger than the inner terrestrial planets.


What is the relative size of the inner planets?

The inner planets are smaller than the outer planets. This may be because the outer planets are called gas giants. This means that gas can accumulate in size at times, and this can be one of the situations.


Which planets are closest together-the inner or the outer planets?

The inner plants. The size and distance of the outer planets means they have longer and more spaced out orbits

How are the four outer planets alike?

The four outer planets are all of the type astronomers call "gas giants", and have no hard, rocky surface per se. The inner planets are all solid rocky "terrestrial" planets. Also, the four outer planets are larger in size and lesser in density than the inner planets.


How is the size of the outer planets different from the size of the inner planets?

They are all bigger

How is Mars and earth alike?

Mars and Earth are very different planets when it comes to temperature, size, and atmosphere, but geologic processes on the two planets are surprisingly similar. On Mars, we see volcanoes, canyons, and impact basins much like the ones we see on Earth.

Are all inner planets the same size?

No.

How are inner planets alike?

No, it is a dwarf planet. Uh.....the question was about Pluto's position in the solar system, not Pluto's size. Pluto was thought to be the ninth planet when discovered in the 1930's, but we now know that Pluto is not a planet. When it was still considered a planet, it was one of the outer planets, about as far as you can get. Mercury, Venus, Terra (earth), and Mars are the inner planets; those with orbits between the Belt and Sol (the asteroid belt and the sun).


What is the main difference between the inner planets and the outer planets?

The inner planets are smaller, and do not have the dense atmospheres of the outer planets. The four inner planets (Mercury, Venus, Earth, and Mars) have warmer temperatures than the exteriors of the outer planets (Jupiter, Saturn, Uranus, and Neptune).The "gas giants" have very hot lower atmospheres, caused by the intense pressure. The atmospheres are mostly hydrogen, but for Uranus and Neptune there are higher levels of water, methane, and ammonia. All of the gas giants have multiple moons and rings, the most visible being the ice rings around Saturn.they are divided by inner and outer and the outer planet are the planets that have bigger planets.


Which characteristics do all inner planets share?

High density, small size.
