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 ...

Astronomers say they have evidence that there may be a hidden planet in our Solar System. Named 'Planet Y', the Earth-sized ...

Astronomers propose a new hypothetical planet, Planet Y, beyond Neptune, based on observed orbital anomalies in the Kuiper belt.

The origin of the differing tilts in the orbits of the planets in our solar system may have been revealed through the ...

Because the Sun’s gravity isn’t strong enough to hold onto such hot gas, the outer atmosphere essentially boils off into space. This “solar wind” permeates the solar system.

Called 3I/ATLAS, the comet is only the third of its kind known to astronomers, and it’s likely been heading our way for billions of years, carrying pristine material from another star system ...

F or the first time, researchers have dated the formation of Jupiter by studying tiny, bead-like spheres found preserved in ...

The solar system has many more moons than the one we can see in the sky. But how many do we actually know about? And how many ...

Over four billion years ago, the solar system was a wild and dangerous place. Swirling clouds of dust and gas slowly turned ...

Technological advances such as the one discussed here are only furthering the potential for clean energy production. Scientists develop incredible gravity-powered system that could change the way ...

Are tiny black holes zipping through our solar system? Scientists hope to find out Scientists have studied black holes with the mass of a star for decades.

What are the weirdest worlds in our solar system, and how did they come to be? From a dwarf planet that looks like a deflated football, to a tiny moon with cliffs taller than Mt. Everest, to the ...
