The 8 primary planets of the solar system. (MARK GARLICK/SCIENCE PHOTO LIBRARY via Getty Images) Saturn is pale yellow due to ammonia crystals in its upper atmosphere and features a prominent ring system made of ice and rock particles that range in size and orbit speeds. The rings are roughly 20 meters (66ft.) thick and extend from 6,630 to
The Definition of a Planet The word goes back to the ancient Greek word planēt, and it means "wanderer." A more modern definition can be found in the Merriam-Webster dictionary which defines a planet as "any of the large bodies that revolve around the Sun in the solar system." In 2006, the International Astronomical Union []

Uranus is the seventh planet from the Sun, and it''s the third largest planet in our solar system – about four times wider than Earth. Uranus is a very cold and windy planet. It is surrounded by faint rings, and more than two dozen small moons as it rotates at a nearly 90-degree angle from the plane of its orbit. This unique tilt makes Uranus

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
Mars is one of the most explored bodies in our solar system, and it''s the only planet where we''ve sent rovers to explore the alien landscape. A rock nicknamed "Cheyava Falls," which has features that may bear on the question
Any natural solar system object other than the Sun, a planet, a dwarf planet, or a moon is called a small body; these include asteroids, meteoroids, and comets. Most of the more than one million asteroids, or minor planets, orbit between Mars and Jupiter in a nearly flat ring called the asteroid belt.
Planet, broadly, any relatively large natural body that revolves in an orbit around the Sun or around some other star and that is not radiating energy from internal nuclear fusion reactions. There are eight planets orbiting the Sun in the solar system.
Terrestrial planets also have a molten heavy-metal core, few moons and topological features such as valleys, volcanoes and craters. making it the hottest planet in the solar system. Venus has

Its surface features are also named after women, both real and mythical. Venus rotates on its axis very slowly. It is so slow that a day that there is longer than a year! Jupiter is the fifth planet from the Sun and the largest of all the solar system planets. It was named after the king of the gods in Roman mythology. With an apparent

5 · 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,
GCSE; WJEC; Stars and planets – WJEC The main features of the solar system. The Earth forms part of a family of eight planets which orbit around the Sun. This solar system forms part of a huge
Our solar system includes the Sun, eight planets, five officially named dwarf planets, and hundreds of moons, and thousands of asteroids and comets. Our solar system is located in the Milky Way, a barred spiral galaxy with two major
Planetary features are named by the International Astronomical Union, founded in 1919. For more information about the names of planets, moons, and features, There may be hundreds of dwarf planets in Pluto''s realm. Our solar system formed about 4.6 billion years ago. The four . planets closest to the Sun — Mercury, Venus, Earth, and Mars —
While Earth is only the fifth largest planet in the solar system, it is the only world in our solar system with liquid water on the surface. Just slightly larger than nearby Venus, Earth is the biggest of the four planets closest to the Sun, all of which are made of rock and metal. Namesake. Namesake. The name Earth is at least 1,000 years old.
Introduction. This seemingly simple question doesn''t have a simple answer. Everyone knows that Earth, Mars and Jupiter are planets. But both Pluto and Ceres were once considered planets until new discoveries triggered scientific debate about how to best describe them—a vigorous debate that continues to this day. The most recent definition of a planet was adopted by the
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.
Nearest to the Sun, only rocky material could withstand the heat when the solar system was young. For this reason, the first four planets – Mercury, Venus, Earth, and Mars – are terrestrial planets. They are all small with solid, rocky surfaces.

The inner Solar System is the region comprising the terrestrial planets and the asteroids. Composed mainly of silicates and metals, the objects of the inner Solar System are relatively close to the Sun; the radius of this entire region is less than the distance between the orbits of Jupiter and Saturn. This region is within the frost line, which is a little less than 5 AU from the Sun.
The solar system is host to two broad categories of planets. The four closest to the sun — Mercury, Venus, Earth and Mars — are the terrestrial planets. They have rocky surfaces enclosed by relatively shallow atmospheres. The gas and ice giants — Jupiter, Saturn, Uranus and Neptune — are outliers.
It includes a single star, planets, their moons, dwarf planets like Pluto and Ceres, and smaller bodies like asteroids, comets, and the outer solar system Kuiper Belt objects. Yet, scientists continue to discover fascinating new findings about our solar system, and Hubble has contributed to these discoveries.
Learn about the planets in our solar system. The solar system has eight planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. There are five officially recognized dwarf planets in our solar system: Ceres, Pluto,
Features of the solar system. The solar system is unique in the cosmos due to a number of distinctive features that differentiate it from other star systems and celestial objects in the universe. These features include: Largest planet in the Solar System (by diameter): Jupiter, with a diameter of approximately 139.8 thousand kilometers.
