When you look at the solar system, you might notice that the planets' orbits are tilted, and oddities in the protoplanetary disk might be to blame.

We all picture the Solar System as a neat cosmic racetrack with planets orbiting the Sun on a flat, organized path. But have ...

There are a couple of ways that scientists can date planets, so which planets formed first in our solar system?

Tests on olivine hint that water-rich exoplanets could generate H2O internally, possibly explaining ocean worlds and even some of Earth’s early water.

Many scientists call Jupiter the architect of the solar system because its immense gravity influenced the orbits of other planets and carved up the gas and dust from which they all emerged. This ...
