Basic Characteristics.
The giant planets are very far from the Sun.

How old are gas giants?
Observations from NASA's Spitzer Space Telescope show that gas giants either form within the first 10 million years of a sun-like star's life, or not at all.
The study offers new evidence that gas-giant planets must form early in a star's history.
The lifespan of sun-like stars is about 10 billion years..

Why is gas giants misleading?
Terminology.
The term gas giant was coined in 1952 by the science fiction writer James Blish and was originally used to refer to all giant planets.
It is, arguably, something of a misnomer because throughout most of the volume of all giant planets, the pressure is so high that matter is not in gaseous form..
Why must a gas giant form in fewer than 10 million years?
However, clouds of gas surrounding young stars don't last long—typically only a few million years.
The problem is to form a solid planet that is large enough to pull in lots of gas while the gas is still available.
This means the solid planet that is the seed for a gas giant has to grow very fast.Nov 9, 2017.
Will Earth turn into a gas giant?
