18.3: Outer Planets

The four planets farthest from the Sun are the outer planets. Figure below shows the relative sizes of the outer planets and the Sun. These planets are much larger than the inner planets and are made primarily of gases and liquids, so they are also called gas giants. This image shows the four outer planets and the Sun, with sizes to scale.

Planet Sizes and Locations in Our Solar System

Mars, the red planet, is the seventh largest planet in our solar system. Mars is about half the width of Earth, and has an equatorial diameter of about 4,221 miles (6,792 kilometers). Mars is the fourth planet from the Sun, orbiting at an average distance of 141.6 million miles (227.9 million kilometers).

5 days ago· Solar system, assemblage consisting of the Sun and those bodies orbiting it: 8 planets with about 210 known planetary satellites; many asteroids, some with their own satellites; comets and other icy bodies; and vast reaches of highly tenuous gas and dust known as the interplanetary medium. The four outer planets are Jupiter, Saturn, Neptune

Gas Giant Facts (The Outer Planets)

Gas giants are large planets that contain more than 10 times the mass of Earth, they are also known as the Jovian or Outer Planets. Their compositions are mostly gases, such as hydrogen, and small amounts of rocky material (mostly at their cores). The four gas giants in our solar system are Jupiter, Saturn, Uranus, and Neptune.

In Depth | Our Solar System – NASA Solar System Exploration

Introduction. The planetary system we call home is located in an outer spiral arm of the Milky Way galaxy. Our solar system consists of our star, the Sun, and everything bound to it by gravity – the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune; dwarf planets such as Pluto; dozens of moons; and millions of asteroids, comets, and meteoroids.

5 days ago· 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,

Outer space

Being essentially empty, outer space allows the earliest (redder) galaxies to be viewed without obstruction, as in the Webb''s First Deep Field image.. Outer space (or simply space) is the expanse that exists beyond Earth''s atmosphere and between celestial bodies. [1] It contains ultra-low levels of particle densities, constituting a near-perfect vacuum [2] of predominantly

The ancient Titans of the solar system are the outer planets: Jupiter, Saturn, Uranus, and Neptune. The inner planets, Mercury, Venus, Earth and Mars, huddling close to the warm Sun, are pebbles by comparison. Stretching from 500 million to 3 billion miles from the Sun, these monsters are as remote as they are mysterious, dwelling so far from

What is the Universe?

In the span of a single human lifetime, space probes have voyaged to the outer solar system and sent back the first up-close images of the four giant outermost planets and their countless moons; rovers wheeled along the surface on Mars for the first time; humans constructed a permanently crewed, Earth-orbiting space station; and the first large

The eight planets of the Solar System with size to scale (up to down, left to right): Saturn, Jupiter, Uranus, Neptune (outer planets), Earth, Venus, Mars, and Mercury (inner planets). A planet is a large, rounded astronomical body that is generally required to be in orbit around a star, stellar remnant, or brown dwarf, and is not one itself. [1] The Solar System has eight planets by the

OverviewFormation and evolutionGeneral characteristicsSunInner Solar SystemOuter Solar SystemTrans-Neptunian regionMiscellaneous populations

The Solar System is the gravitationally bound system of the Sun and the objects that orbit it. It formed about 4.6 billion years ago when a dense region of a molecular cloud collapsed, forming the Sun and a protoplanetary disc. The Sun is a typical star that maintains a balanced equilibrium by the fusion of hydrogen into helium at its core, releasing this energy from its outer photosphere. Astronomers
