Solar System

A star system is a group of planets, meteors, or other objects that orbit a large star. While there are many star systems, including at least 200 billion other stars in our galaxy, there is only one solar system. That''s because our sun is known by its Latin name, Sol. The solar system includes everything that is gravitationally drawn into the sun''s orbit. Use these resources to learn about

Galaxy

A galaxy is a system of stars, stellar remnants, interstellar gas, dust, and dark matter bound together by gravity. [1] [2] The word is derived from the Greek galaxias (γαλαξίας), literally ''milky'', a reference to the Milky Way galaxy that contains the Solar System.Galaxies, averaging an estimated 100 million stars, [3] range in size from dwarfs with less than a thousand stars, [4] to

The Solar System is located in the Milky Way, a barred spiral galaxy with a diameter of about 100,000 light-years containing more than 100 billion stars. The Sun is part of one of the Milky Way''s outer spiral arms, known as the Orion–Cygnus Arm or Local Spur. It is a member of the thin disk population of stars orbiting close to the galactic plane.

Galaxy | Definition, Formation, Types, Properties, & Facts

· Galaxy, any of the systems of stars and interstellar matter that make up the universe. Many such assemblages are so enormous that they contain hundreds of billions of stars. Virtually all galaxies appear to have been formed soon after the universe began, and they pervade all space that is viewable by modern telescopes.

Planets in Order From the Sun | Pictures, Facts, and Planet Info

The solar system encompasses planets, moons, asteroids, comets, and dwarf planets, that orbit around the Sun at its center. The solar system was created about 4.6 billion years ago in a collapsing cloud of gas and dust that eventually flattened into a rotating disk. The two main regions of the solar system are the inner and outer solar systems.

Milky Way

The Milky Way [c] is the galaxy that includes the Solar System, with the name describing the galaxy''s appearance from Earth: a hazy band of light seen in the night sky formed from stars that cannot be individually distinguished by the naked eye.. The Milky Way is a barred spiral galaxy with a D 25 isophotal diameter estimated at 26.8 ± 1.1 kiloparsecs (87,400 ± 3,600 light-years),

The Sun is located in the Milky Way galaxy in a spiral arm called the Orion Spur that extends outward from the Sagittarius arm. bringing with it the planets, asteroids, comets, and other objects in our solar system. Our solar system is moving with an average velocity of 450,000 miles per hour (720,000 kilometers per hour). But even at this

Science 101: The Solar System

Transcript (English) - [Narrator] Our solar system is one of over 500 known solar systems in the entire Milky Way galaxy. The solar system came into being about 4.5 billion years ago when a cloud of interstellar gas and dust collapsed, resulting in a solar nebula, a swirling disc of material that collided to form the solar system.

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

How did scientists determine our location within the Milky Way galaxy

The essential modern picture is that our solar system is located on the inner edge of a spiral arm, about 25,000 light-years from the center of the galaxy, which is in the direction of the

Solar system | Definition, Planets, Diagram, Videos, & Facts

· solar system, assemblage consisting of the Sun—an average star in the Milky Way Galaxy—and those bodies orbiting around it: 8 (formerly 9) planets with more than 210 known planetary satellites (moons); 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 Milky Way Galaxy

Our Solar System is about 25,000 light years away from the center of our galaxy – we live in the suburbs of our galaxy. Just as the Earth goes around the Sun, the Sun goes around the center of the Milky Way. It takes 250 million years for our Sun and the solar system to go all the way around the center of the Milky Way.

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.

The Milky Way Galaxy

Astronomers use this telescope to observe objects in the Solar System and the Milky Way, as well as other galaxies, including the supermassive black holes known as quasars. Astronomers also use the 1.2-Meter Telescope to observe star systems that might contain exoplanets, which is a major program for the observatory.

Galaxy, Universe & Solar System | Overview & Differences

A galaxy is a huge collection of gas, dust, and billions of stars and their solar systems, all held together by gravity. Our sun is just one of at least 200 billion stars in the Milky Way galaxy.

Solar System

The solar system is 4.6 billion years old, and is situated in one arm of the Milky Way Galaxy. On a clear night, the ribbon of stars that cuts across the sky is the Milky Way. The solar system is heliocentric, meaning all solar system objects orbit the sun in a counterclockwise direction in an area called the ecliptic plane. A year

The Milky Way Galaxy

Like early explorers mapping the continents of our globe, astronomers are busy charting the spiral structure of our galaxy, the Milky Way. Using infrared images from NASA''s Spitzer Space Telescope, scientists have discovered that the Milky Way''s elegant spiral structure is dominated by just two arms wrapping off the ends of a central bar of stars.
