When looking at our solar system, the planets going around the sun seem to be set up in a pretty organized fashion. They are all orbiting in the same direction, and exist on a roughly flat planetary ...

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 ...

Most planet-forming disks have warps that can lead to planets on inclined orbits, which could explain where the tilt of Earth's orbit came from. The origin of the differing tilts in the orbits of the ...

All of our solar system’s planets are lining up to parade through the night sky at once. This extraordinary celestial event ...

The workings of our solar system are roughly the same now as they have been for millions of years. Moons circle their planets, the planets circle the sun, the sun’s magnetic fields and sunspots wax ...

Over 80% of exoplanetary systems with three or more planets exhibit a "peas-in-a-pod" architecture, characterized by similarly sized planets closely spaced and orbiting near their star. A new study ...

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, ...

The search for an unknown planet in our solar system has inspired astronomers for more than a century. Now, a recent study suggests a potential new candidate, which the paper’s authors have dubbed ...
