The cosmic clock of the solar system: How angular momentum shaped planetary orbits and regular moons
Explore the story of our solar system’s formation, tracing how a vast cloud of gas and dust collapsed under gravity, collisions, and angular momentum to create a thin, spinning protolanetary disc.
Studying the orbits of thousands of exoplanets shows that large planets tend to have elliptical orbits, while smaller planets tend to have more circular orbits. This split coincides with several other ...
From meteorites that impact Earth, to a moon that orbits backwards, to an imposter lurking in the asteroid belt, a variety of strange, wandering worlds are rewriting what we know – and even how we ...
