The cosmic giants that defy the limits of rocky worlds

Chthonian Planets and Mega-Earths · 13:54 · Video: Kyplanet · Watch at the source

In short: Most rocky planets have a size ceiling, yet some exoplanets shatter these boundaries. This video explores the formation of Chthonian planets and Mega-Earths, using Space Engine visuals to illustrate these massive celestial anomalies.

While typical rocky planets remain relatively small, astronomers have identified several outliers that far exceed the dimensions of standard super-Earths. Planetary development theories are tested by enormous entities such as TOI-1853 b, GJ 523 b, and TOI-849 b.

The video examines the specific mechanisms that allow for the creation of Chthonian planets and Mega-Earths. By visualizing these worlds, the content helps clarify how such enormous rocky masses can emerge in our galaxy, providing a deeper look into the diversity of planetary evolution.
