What is our Solar System and how many stars does it have? How did the Sun and Solar System form, and what are other planetary systems like?
The solar system has one star, eight planets, five dwarf planets, at least 290 moons, more than 1.3 million asteroids, and about 3,900 comets.
Is it possible that our original home exists as a great collection of stars, a star cluster known as Messier 67 (shown above), a gathering of suns and stellar remnants some 2,700 light-years distan...
Our universe is a vast expanse, filled with wonders beyond our wildest imagination. From the dazzling planets of our solar system to the distant stars that twinkle in the night sky, there is so muc...
The Sun is the only star in our solar system. It is the center of our solar system, and its gravity holds the solar system together. Everything in our solar system revolves around it – the planets, asteroids, comets, and tiny bits of space debris. Measuring a “day” on the Sun is complicated. The Sun is made of super-hot, electrically charged gas called plasma. This plasma rotates at diffe ...
Multiple Star Systems Our solar system, with its eight planets orbiting a solitary Sun, feels familiar because it’s where we live. But in the galaxy at large, planetary systems like ours are decide...

Explore the eight (or nine) planets of the solar system in order from nearest to the sun and discover the many wonders of our solar system along the way.
A significant proportion of the stardust in the solar system may have come from supergiant stars going supernova.
Around the same time our ancestors left Africa, a dim red dwarf star came to within 0.8 light-years of our Sun, marking the closest known flyby of a star to our Solar System. New research suggests Scholz’s Star, as it’s known, left traces of this interstellar encounter by perturbing some comets in the outer Oort Cloud. Though Scholz’s Star visited the outer reaches of our Solar System some 70,000 years ago, awareness of this celestial meet-and-greet first emerged three years ago in a study published in the Astrophysical Journal Letters. ...
