Could a gas giant turn into a star?

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.

Could you light a gas giant on fire?

No. Gas giants are composed of Hydrogen, Helium, Methane and Ammonia. There is no Oxygen to facilitate a fire (oxidation).

Why do gas giants not become stars?

A gas giant is a giant planet composed mainly of hydrogen and helium. Gas giants are also called failed stars because they contain the same basic elements as a star. The outermost portion of their hydrogen atmosphere contains many layers of visible clouds that are mostly composed of water and ammonia.

Will Jupiter turn into a star?

In order to turn Jupiter into a star like the Sun, for example, you would have to add about 1,000 times the mass of Jupiter. So, Jupiter cannot and will not spontaneously become a star, but if a minimum of 13 extra Jupiter-mass objects happen to collide with it, there is a chance it will.

Are gas giants completely gas?

A gas giant is a large planet composed mostly of gases, such as hydrogen and helium, with a relatively small rocky core. The gas giants of our solar system are Jupiter, Saturn, Uranus and Neptune. These exoplanets (as they are called) are being examined to learn more about how our solar system came to be.

Can Earth become a star?

No, Earth will never be able to turn into a star. For Earth to become a brown dwarf (not a true star) and start fusing deuterium, it would have to gain 4130.76 M⊕ (Earth masses). However, the lowest mass stars, called red dwarfs, have a lower bound of 0.07–0.077 M☉ (solar mass). That’s 23,300–25,600 M⊕.

Does Earth have a second sun?

Our Sun is a solitary star, all on its ownsome, which makes it something of an oddball. But there’s evidence to suggest that it did have a binary twin, once upon a time. So, if not for some cosmic event or quirk, Earth could have had two suns. But we don’t.

Can planets turn into black holes?

If a black hole were to form from the Earth itself, it would create an event horizon just 1.7 centimeters in diameter. If, somehow, the electromagnetic and quantum forces holding the Earth up against gravitational collapse were turned off, Earth would quickly become a black hole.

What happens when a planet becomes a gas giant?

When a planet reaches a few times the mass of Earth, the atmosphere will grow rapidly, faster than the solid part of the planet, eventually forming a gas giant planet like Jupiter. I simulated the growth of a solid planet in a cloud of gas surrounding a young star.

Is Jupiter big enough to ignite a star?

The planet Jupiter is the largest in our Solar System, but is it large enough to ignite? Stars burn as a result of thermonuclear reactions deep in their cores. An object with a mass less than about eight percent of the Sun’s cannot ignite significant nuclear reactions in its core. These objects are ‘failed’ stars called brown dwarfs.

What happens when a large cloud of interstellar gas hits Jupiter?

This releases the huge amount of energy that makes stars shine. If a large cloud of interstellar gas came Jupiter’s way, maybe the planet could gain enough extra mass to start fusion. Fusion would be short lived if it became a brown dwarf, an object midway between star and planet.

Is Jupiter a gas giant or a brown dwarf?

Jupiter lies pretty close to the limit of what we’d call a gas giant. But by definition, if a gas giant is massive enough to ‘ignite’ deuterium fusion it is not a gas giant at all, but a brown dwarf.
