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

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

Astronomers have discovered a distant dwarf planet orbiting beyond Neptune — a frozen world so far from the Sun that it challenges everything we know about how the solar system formed.

Astronomers are investigating a strange class of exoplanets known as eccentric warm Jupiters — massive gas giants that orbit their stars in unexpected, elongated paths. Unlike their close-orbiting ...

The discovery of ancient water in a planet-forming disk reveals that some of the water found in comets—and maybe even Earth—is older than the disk's star itself, offering breakthrough insights into ...
