About 4. 6 billion years ago, the Solar System formed from a cloud of dust and gas collapsing in on itself due to gravity.

The workings of our solar system are roughly the same now as they have been for millions of years. Moons circle their planets, the planets circle the sun, the sun’s magnetic fields and sunspots wax ...

Tiny shavings from a single meteorite could completely overturn our understanding of how the solar system formed, after the space rock turned out to be older than expected. Previous research suggests ...

Discover the new insights into solar system formation through pebble accretion theory and groundbreaking computer simulations. Scientists have long puzzled over how our solar system’s planets formed, ...

Our solar system is a smashing success. A new study suggests that from its earliest period—even before the last of its nebular gas had been consumed—Earth's solar system and its planets looked more ...

Thirty years ago, on a crisp October day in 1995, two Swiss astronomers changed the course of cosmic history. Michel Mayor ...

A new study suggests yet another theory for a possible extra planet in our solar system, likely of a size between Mercury and ...

Exoplanet hunters Christopher Watson and Annelies Mortier explain the long search for a 'twin Earth' capable of sustaining ...

The JWST has studied the chemical composition of a moon-forming disk circling a giant planet 625 light-years away.

In addition to planets such as Earth and Mars, there are many asteroids in the solar system. A map of such a solar system planet and 18,000 asteroids, along with their orbits, is available. An Orbit ...
