What is a comet nucleus?
Quick Answer
A comet nucleus is the solid icy core of a comet, made of frozen gases, dust, and rocky material.
The Full Story
The nucleus is the central body of a comet, often only a few kilometers across. When a comet approaches the Sun, heat causes ices to vaporize and release gas and dust, forming a glowing coma and often a tail. Famous missions such as ESA’s Rosetta studied comet 67P/Churyumov-Gerasimenko up close in 2014. Comet nuclei preserve ancient material from the early Solar System.
