No. A gas giant will never have sufficient mass to become a star on its own. The only way to form a star is for a sufficient mass to accumulate for pressures necessary for fusion to occur.

The dividing line between these brown dwarfs and gas planets occurs at about 1 per cent of the mass of the Sun. Objects less massive than that can never achieve the core temperatures required for thermonuclear reactions. This corresponds to about 13 times the mass of Jupiter, meaning that Jupiter itself is incapable of ever ‘igniting’.

The largest a gas giant can get without being a star itself is a L class brown dwarf, which is just under the size needed for fusion to start. The least massive star known is 2MASS J0523-1403, which is just over the fusion threshold. You can get smaller stars (in radius), like white dwarfs, or neutron stars, but they are going to have a lot ...

If a large cloud of interstellar gas came Jupiter’s way, maybe the planet could gain enough extra mass to start fusion. If it accreted even more mass, just enough to become a true star, it would be a dim red dwarf. Its radiation would barely affect us and it wouldn’t look very different to now.

The gas giant may not be a star, but Jupiter is still a Big Deal. Its mass is 2.5 times that of all the other planets combined. It's just that, being a gas giant, it has really low density: around 1.33 grams per cubic centimetre; Earth's density, at 5.51 grams per cubic centimetre, is just over four times higher than that of Jupiter.

It is one of the smallest stars astronomers have seen with a gas giant, and apparently, our models can’t yet explain how this gas giant came to be so close to its parent star. The planet in...

Could a gas giant turn into a star? « Reply #1 on: 18/09/2008 11:34:46 » Why yes, *Warning..very crude explanation follows*....... yes it could...BUT, only if it continued to grow in mass and accumulate enough stuff to make it heavy/big enough.

Contrary to what some people may say, Jupiter is not a failed star. It is a gas giant planet, a type of planet which we now know to be fairly common throughout the universe. Gas giant planets range anywhere between 0.3 to 60 times the mass of Jupiter.

Gas giants are sometimes known as failed stars because they contain the same basic elements as a star. Jupiter and Saturn are the gas giants of the Solar System . The term "gas giant" was originally synonymous with "giant planet", but in the 1990s it became known that Uranus and Neptune are really a distinct class of giant planet, being composed mainly of heavier volatile substances (which are referred to as "ices").
