Saturn

Saturn is the sixth planet from the Sun and the second largest planet in our solar system. Adorned with a dazzling system of icy rings, Saturn is unique among the planets. Saturn is a massive ball made mostly of hydrogen and helium. The farthest planet from Earth discovered by the unaided human eye, Saturn has been known since ancient times.

Inner Solar System

Planetary Systems

Planetary Systems Our solar system consists of the Sun, whose gravity keeps everything from flying apart, eight planets, hundreds of moons, and billions of smaller bodies – from comets and asteroids to meteoroids and tiny bits of ice and rock. Similarly, exoplanetary systems are groups of non-stellar objects circling stars other than the Sun, and []

Solar System

The extent of the Solar System is defined by the solar wind — particles driven by the Sun''s magnetic field — and gravitational influence. The heliopause is the boundary created when solar wind particles collide with interstellar gas as the Solar System moves through the galaxy. The gravitational edge is much farther and is defined by the

Chapter 1: The Solar System

Upon completion of this chapter, you will be able to classify objects within the solar system, state their distances of in terms of light-time, describe the Sun as a typical star, relate its share of the mass within the solar system, and compare

The Habitable Zone

The definition of "habitable zone" is the distance from a star at which liquid water could exist on orbiting planets'' surfaces. Habitable zones are also known as Goldilocks'' zones, where conditions might be just right – neither too hot nor too cold – for life.

The Kuiper Belt

Explore our solar system with NASA''s Eyes on the Solar System. NASA/JPL-Caltech/VTAD. Similar to the asteroid belt, the Kuiper Belt is a region of leftovers from the solar system''s early history. Like the asteroid belt, it has also been shaped by a giant planet, although it''s more of a thick disk (like a donut) than a thin belt.

Our Solar System

Our solar system is made up of a star—the Sun—eight planets, 146 moons, a bunch of comets, asteroids and space rocks, ice, and several dwarf planets, such as Pluto. The eight planets are Mercury, Venus, Earth, Mars,

5 days ago· The solar system''s several billion comets are found mainly in two distinct reservoirs. The more-distant one, called the Oort cloud, is a spherical shell surrounding the solar system at a distance of approximately 50,000 astronomical units (AU)—more than 1,000 times the distance of Pluto''s orbit. The other reservoir, the Kuiper belt, is a thick disk-shaped zone whose main

Stars

Astronomers estimate that the universe could contain up to one septillion stars – that''s a one followed by 24 zeros. Our Milky Way alone contains more than 100 billion, including our most well-studied star, the Sun. Stars are giant balls of hot gas – mostly hydrogen, with some helium and small amounts of other elements. []

In Depth | Eris – NASA Solar System Exploration

Eris is one of the largest known dwarf planets in our solar system. It''s about the same size as Pluto but is three times farther from the Sun. At first, Eris appeared to be larger than Pluto. This triggered a debate in the scientific community that led to the International Astronomical Union''s decision in 2006 to clarify the definition of a planet.

What is a Planet?

In so doing we have discovered a section in our solar system called the Kuiper Belt that has the potential to hold hundreds, if not thousands, of objects similar to Pluto and Eris. Much like other sciences, such as Biology, where one may discover a new species, classification is a common and needed process which groups like objects for purposes

What is a Planet?

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 []

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

Asteroids

Overview Asteroids, sometimes called minor planets, are rocky, airless remnants left over from the early formation of our solar system about 4.6 billion years ago. Most asteroids can be found orbiting the Sun between Mars and Jupiter within the main asteroid belt. Asteroids range in size from Vesta – the largest at about 329 miles []
