Question

why Jupiter, Saturn, Uranus and Neptune are call Jovian planet s​

Answer 1

Answer:

Astronomers sometimes categorize Uranus and Neptune as “ice giants” because their composition differs from Jupiter and Saturn. This is because they are mostly composed of water, ammonia, and methane.

Answer 2

Beyond our Solar System’s “Frost Line” – the region where volatiles like water, ammonia and methane begin to freeze – four massive planets reside. Though these planets – Jupiter, Saturn, Uranus and Neptune – vary in terms of size, mass, and composition, they all share certain characteristics that cause them to differ greatly from the terrestrial planets located in the inner Solar System.
