Our Sun - In Depth / Sun â NASA Solar System Exploration ~ The Sun is a yellow dwarf star, a hot ball of glowing gases at the heart of our solar system. Its gravity holds the solar system together, keeping everything â from the biggest planets to the smallest particles of debris â in its orbit. The connection and interactions between the Sun and Earth drive the seasons, ocean currents, weather, climate, radiation belts and auroras. Though it is .
Overview / Sun â NASA Solar System Exploration ~ Our Solar System Sun Facts The Sun is the largest object within our solar system, comprising 99.8% of the systemâs mass. The Sun is located at the center of our solar system, and Earth orbits 93 million miles away from it. Though massive, the Sun still isnât as large as other types of stars. Itâs classified as a yellow dwarf star.
Harvard Astronomers Propose That Our Star System Used to ~ A team of Harvard astronomers have a wild new theory: the Sun used to have a companion star, making our solar system a binary one during its ancient history.

Harvard scientists' new study claims sun once had a binary ~ The binary capture model offers significant improvement and refinement, which is seemingly obvious in retrospect: most Sun-like stars are born with binary companions." If early stellar composition helped in the capturing of Oort cloud, the implications of our understanding of the solar system's formation would be important. Loeb said, "Binary systems are far more efficient at capturing objects .
Scientists reveal first-ever photo of a solar system like ~ The star, known as TYC 8998-760-1 and located in the Southern constellation of Musca, is only 17 million years old, which researchers called a "very young version of our own sun." Comparatively .
Composition of the Solar System / SpaceNext50 ~ Solar system, assemblage consisting of the Sunâan average star in the Milky Way Galaxyâand those bodies orbiting around it: 8 (formerly 9) planets with about 170 known planetary satellites (moons); countless 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.
Wandering stars pass through our solar system surprisingly ~ Scholzâs Star and its binary brown dwarf fly by our solar system some 70,000 years ago in this artistâs illustration. Our sun shines bright in the background. Michael Osadciw/University of .
Celestia: Home ~ You can travel throughout the solar system, to any of over 100,000 stars, or even beyond the galaxy. All movement in Celestia is seamless. The exponential zoom feature lets you explore space across a huge range of scales, from galaxy clusters down to spacecraft only a few meters across. A 'point-and-goto' interface makes it simple to navigate through the universe to the object you want to .
The life cycle of a Sun-like star (annotated) â Exoplanet ~ Following this stage, the star will push its outer layers into the surrounding space to form an object known as a planetary nebula, while the core of the star itself will cool into a small, dense remnant called a white dwarf star. Marked on the lower timeline are where our Sun and solar twins 18 Sco and HIP 102152 are in this life cycle. The .
StarChild: The Sun - NASA ~ The Sun is a medium size star known as a yellow dwarf. It . Because the Sun is so massive, it exerts a powerful gravitational pull on everything in our solar system. It is because of the Sun's gravitational pull that Earth orbits the Sun in the manner that it does. X-rays from the Sun : Parts of the Sun: The Sun has several layers: the core, the radiation zone, the convection zone, and the .
EmailPDF - The University of Arizona ~ OUR SOLAR SYSTEM The sun is the center of our solar system. It is the largest body in our solar system. Nine planets follow paths called orbits around the sun. The shape of each orbit is called an ellipse. An ellipse is a flattened circle (see the picture at the bottom of page 3). The nine planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto. Moons, asteroids .
ESA - Space for Kids - The Solar System and its planets ~ The Solar System is made up of the Sun and all of the smaller objects that move around it. Apart from the Sun, the largest members of the Solar System are the eight major planets. Nearest the Sun are four fairly small, rocky planets - Mercury, Venus, Earth and Mars. Beyond Mars is the asteroid belt â a region populated by millions of rocky objects. These are left-overs from the formation of .
Sun 101 - National Geographic ~ Our sun is the largest and most massive object in the solar system. Itâs more than 100 Earths wide and could theoretically fit all eight planets inside nearly 600 times. It also contains approximately 99.8% of all the mass in the solar system. Because of this mass, the sun has a great âpullâ on the fabric of space, creating a .
The Sun Steals Comets from Other Stars / Science Mission ~ And he believes this kind of thievery accounts for most of the comets in the Oort Cloud at the edge of our solar system. "We know that stars form in clusters. The Sun was born within a huge community of other stars that formed in the same gas cloud. In that birth cluster, the stars were close enough together to pull comets away from each other via gravity. It's like neighborhood children .
Solar System and Beyond / NASA ~ NASAâs exploration spans the universe. Observing the sun and its effects on Earth. Delving deep into our solar system. Looking beyond to worlds around other stars. Probing the mysterious structures and origins of our universe. Everywhere imaginable, NASA is out there.
Bad Astronomy / Was the Sun once part of a binary star system? ~ It's possible P9 once orbited another star that passed close to the Sun, and the gravity of our star stripped it away, the Sun keeping it for its own. But the physics of that makes it hard to do as well; usually in an encounter like that the planet gains so much energy that it gets flung away from both systems. But that's if the Sun is alone. If instead it were part of a binary system when it .
