A village in Kent is home to what is thought to be the world's largest scale model of the solar system and beyond, created to ...

The early solar system may have been far more chaotic than we ever imagined. A new study published in Icarus suggests that our solar system might have once hosted an additional giant planet, whose ...

Key science: Stellar dynamics, N-body simulations, planetary orbital stability, and galactic gravitational potentials.

Our solar system may have hosted up to six giant planets in its first hundred million years, a new study suggests. The ...

Planets may begin forming much earlier than scientists once believed during the final stages of a star s birth, not afterward. This bold new model, backed by simulations from researchers at SwRI, ...

Planets are bodies that orbit a star and have sufficient gravitational mass that they form themselves into roughly spherical shapes that, in turn, exert gravitational force on smaller objects around ...

In 1995, the discovery of 51 Pegasi b, a massive planet orbiting its star closely, revolutionized astronomy. This finding ...

In the remote outer reaches of planetary systems, far beyond the orbit of known planets, enormous and mysterious worlds silently loop around their stars. Some drift as far as 10,000 times the distance ...
