22.10: Inner vs. Outer Planets

The four planets closest to the Sun—Mercury, Venus, Earth, and Mars—are the inner planets or terrestrial planets (Figure below). 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. They have shorter orbits around the Sun and they spin

What are the characteristics of a terrestrial planet?

Terrestrial planets share some similar characteristics that make them a unique class of their own. First of all, terrestrial planets have a distinct composition. They are mostly composed of silicate rock and metal. These planets have solid surfaces, so we have something to land on these planets.

Inner Planets – Physical Science

Geologically, the inner planets are all made of cooled igneous rock with iron cores, and all have been geologically active, at least early in their history. None of the inner planets has rings. Earth. Although Earth is the third planet out from the Sun this lesson will start here. We know a lot more about Earth, so what we know can be used for

Solar System Facts

The order and arrangement of the planets and other bodies in our solar system is due to the way the solar system formed. Nearest to the Sun, only rocky material could withstand the heat when the solar system was young. For this reason,

Mercury Facts

Mercury is the smallest planet in the Solar System. One of five planets visible with the naked eye a, Mercury is just 4,879 Kilometres across its equator, compared with 12,742 Kilometres for the Earth. Mercury is the second densest planet. Even though the planet is small, Mercury is very dense. Each cubic centimetre has a density of 5.4 grams

What are the differences between the inner and outer

The Inner Solar System

There are four rocky, or terrestrial, planets: Mercury, Venus, Earth, and Mars.These planets are called terrestrial planets because they are made up of rocks and metals and have solid surfaces. But even though they''re made of the same materials, the four rocky planets in the Solar System aren''t the same.. In many ways, all the rocky planets are similar.

Solar system

· Solar system - Planets, Moons, Orbits: The eight planets can be divided into two distinct categories on the basis of their densities (mass per unit volume). The four inner, or terrestrial, planets—Mercury, Venus, Earth, and Mars—have rocky compositions and densities greater than 3 grams per cubic cm. (Water has a density of 1 gram per cubic cm.) In contrast,

Three Major Characteristics of the Inner Planets

The inner planets are much smaller than Jupiter, Saturn, Uranus and Neptune, and they all possess iron cores. The easiest spatial distinction between the inner planets and outer planets in the solar system is the asteroid belt. All four of the terrestrial planets fall within the asteroid belt (closer to the sun), and all the gas giants, dwarf

Solar System—Planets and Their Moons

The eight planets can be divided into two distinct categories on the basis of their densities (mass per unit volume). The four inner, or terrestrial, planets—Mercury, Venus, Earth, and Mars—have rocky compositions and densities greater than 3 grams per cubic cm. (Water has a density of 1 gram per cubic cm.) In contrast, the four outer planets, also called the Jovian, or giant, planets

Solar System Inner & Outer Planets | Dwarf Planets

· There are 8 officially recognized Solar System planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Most of them, except Mercury and Venus, have their own natural satellites, commonly called "moons."

Inner Solar System

Inner Solar System. Planetary Science missions to the inner solar system extend mankind''s presence to the rocky worlds and help to unlock the secrets of the solar systems'' composition, history and evolution, and how life on Earth began.

What are the differences between the inner and outer planets?

The fourth difference between inner and outer planets is their temperature. The inner planets have higher temperatures because they are closer to the Sun. Mercury, the closest planet to the Sun, has an average surface temperature of 333 degrees Fahrenheit contrast, Neptune has an average surface temperature of -350 degrees Fahrenheit.

4 FAQs about [Inner planets facts]

What is the difference between inner and outer planets?

The inner planets rotate slower than the outer planets, which makes them more round at their poles. The inner planets are also denser than the outer planets. The thick atmosphere also protects Venus from meteors as they tend to disintegrate before they can pass through to the planet's surface.

What are the characteristics of the inner planets?

While the inner planets are rocky planets, the outer planets are referred to as gas giants. Inner planets have a mostly iron core, surrounded by a mantle. The surface of the inner planets is characterized by volcanoes, canyons, craters, and mountains, and earth is the only one known to have water on its surface.

What is the order of the inner planets?

The inner planets (in order of distance from the sun, closest to furthest) are Mercury, Venus, Earth and Mars. After an asteroid belt comes the outer planets, Jupiter, Saturn, Uranus and Neptune. The interesting thing is, in some other planetary systems discovered, the gas giants are actually quite close to the sun.

What is the only planet with life?

As yet Earth is the only planet known to have life. The presence of liquid water, the ability of the atmosphere to filter out harmful radiation, and many other features make the planet uniquely suited to harbor life.
