When my colleagues and I send them out to explore our solar system, it's important for us to understand the 3D map of our ...

The Sun is an incandescent but benevolent dictator. For billions of years, it’s kept our star system well organized through the influence of its powerful gravity. All the planets revolve around it on ...

The orbits of the planets around the Sun have been the source for many a scientific debate. Their current orbital properties are well understood but the planetary orbits have evolved and changed since ...

A new study suggests that a close encounter with a massive interstellar object, possibly eight times the mass of Jupiter, may ...

Ever since Isaac Newton famously talked about gravity, its dominance as a force in our solar system has been well known. It's responsible for the orbits of the planets and their satellites, but there ...

A rare discovery beyond Neptune is forcing scientists to rethink early solar system dynamics and the forces that shaped ...

Scientists say studying objects like Ammonite, despite their immense distance, offers valuable insight into the solar ...

A massive interstellar object passing through our solar system during its formative years likely altered the orbits of planets into trajectories observed today, a new study says. Interactions with ...

SPACE (KXAN) — A star flying through the night sky may be the fastest-moving solar system in our galaxy. Possibly a planet a little larger than Neptune orbiting a small star, the system could be ...

3I/ATLAS captured the world's attention last month as the comet raced past the Earth, but some believed that it could have ...
