The Solar System is home to a remarkable range of planets, from tiny rocky worlds to massive gas giants. But just how big are ...

A study of 909 planets and 355 stars reveals that, unlike our solar system, other planetary systems are distinguished by strict regularity.

The planets' sizes and orbits distinguish them from asteroids, comets, and meteoroids, as well as icy objects beyond Neptune in the Kuiper Belt, like the dwarf planet Pluto.

Exoplanets can come in a variety of sizes and masses. If you were to plot on a graph how many planets of each size astronomers have discovered, you'd find two peaks: one at 1.4 times Earth 's ...

And yet, when it comes to sizes of planets, specifically their mass and radius, there are some limitations. And for that, we have physics to blame. I am a planetary astrophysicist and I try to ...

So, while there are no super huge rocky planets or small fluffy planets, there is still a huge amount of diversity in planet sizes, geometries and compositions.
