Earth and Mars were formed from material that largely originated in the inner Solar System; only a few percent of the building blocks of these two planets originated beyond Jupiter’s orbit. A group of ...

Tiny grains from asteroid Ryugu are revealing clues to the magnetic forces that shaped the far reaches of the solar system over 4.6 billion years ago. The findings suggest the distal solar system ...

Far beyond Neptune, astronomers have finally confirmed a compact clump of icy worlds hiding inside the Kuiper Belt, a feature ...

Illustration comparing the planets of the Solar System and the Sun on the same scale. The planets are shown to scale relative to each other but their distances are not. From left to right the bodies ...

New research suggests that a binary pair of Kuiper Belt objects, known as the Altjira system, is actually made up of three separate bodies orbiting one another in a complex triad. This rare orbital ...

MIT scientists analyzed one of several particles (shown in black) from the asteroid Ryugu, and found evidence that a weak magnetic field likely existed in the outer solar system where the asteroid is ...
