Evidence that rocky planets beyond Jupiter formed as rapidly, and at the same time, as the inner planets could transform our ...

Today, Ceres is the only dwarf planet located in the inner solar system and the largest object in the asteroid belt between Mars and Jupiter. Ceres is approximately 585 miles ...

Instead, some of it formed a disk that ultimately would condense into the planets and other, smaller members of the solar system. Here are the objects in our inner solar system. The Sun NASA’s ...

The violence isn't confined to the inner solar system, either. The outer planet Uranus has a severe tilt, as the planet sits almost completely on its side.

The Sun and planets of our solar system all formed from the same cloud of gas and dust, but the planets’ compositions vary with mass and distance from our star.

A cloud of collapsing gas created our Sun, the first thing to form in our solar system. This happened about 4½ billion years ago.. Then the planets began to emerge, as the billions of particles ...

This artist’s concept depicts one of the solar system’s inner planets slamming into Earth after being nudged on a collision course by a passing star. Such a world-shattering cataclysm is ...

This process, called accretion, is how everything in the solar system – planets, moons, comets and asteroids – came into being. Telescopes can see young solar systems being born.

Astronomers have discovered the earliest seeds of rocky planets forming in the gas around a baby sun-like star, providing a ...

Embark on a thrilling journey through our Solar System, exploring the inner planets and space travel possibilities. We start with an introduction to the incredible potential of space travel and how ...

If confirmed, these planets would show that the outer planets in our own solar system may very well survive the sun’s demise, even if the inner planets most likely will not.

NASA artist’s conception of a brown dwarf (main) and stock image of the planets in the solar system (inset). An object between 2 and 50 times the mass of Jupiter may have flown through our ...
