Start with a planet hitting the earth

Sirius A tore Sirius B apart bit by bit.

Sirius B was swallowed up bit by bit by Sirius A.

This process seemed to take some time.

Chen Yuan was a little depressed just watching Sirius B being swallowed.

"If I could swallow all of Sirius B, I would definitely become a star directly. What a pity."

Chen Yuan looked at his current mass and volume.

Chen Yuan now has exceeded the volume and mass of Jupiter, but the volume is only slightly larger than the previous Jupiter.

But Chen Yuan's mass is much larger than Jupiter, estimated to be twice the mass of Jupiter.

There is a limit to the size of a planet.

When the size of a planet reaches that of Jupiter, it is already close to the limit.

After that, further increase can only increase mass and density, but when the mass is large enough, nuclear fusion will form and it will become a star.

The reason why Chen Yuan currently has twice the mass, but the volume is only slightly larger than Jupiter.

Of course, there are exceptions.

Some planets are larger than Jupiter because they are very close to the star.

The heat on the surface of the planet is extremely high, so the volume expands and becomes much larger than Jupiter.

In the absence of special conditions.

The limit of the volume of a planet is similar to that of Jupiter.

At present, Chen Yuan has reached his volume limit, which is slightly larger than Jupiter.

"Fortunately, although it can't become a star yet, with the current volume, it is no problem to swallow Jupiter."

Compared with when he first came, the volume is much larger, and the mass has tripled.

Compared with Jupiter, Chen Yuan has now surpassed Jupiter, of course, compared with a real star.

Still can't do it.

Take the Sirius A in front of him as an example. Chen Yuan is still very, very small now.

"It will take some time to become a star."

"Go back to the solar system first and swallow the planet of luck and Jupiter."

Thinking of this, Chen Yuan used his spiritual sense to control his body to fly in the direction of the solar system.

Leaving the location of Sirius.

Chen Yuan flew back into interstellar space.

I don't know how long he will fly.

Chen Yuan returned to the Oort Cloud of the solar system.

Through his perception ability, Chen Yuan took in the solar system.

From the time Chen Yuan left the solar system to Sirius, and then from Sirius back to the solar system, he didn't know how much time had passed.

And seeing the solar system at this moment.

Chen Yuan was a little stunned.

The position of Jupiter is much closer to the sun.

Now the position of Jupiter has reached the position of Venus before.

And the previous Venus has disappeared.

"What's going on?"

"Where did Venus go? Why is Jupiter so close to the sun?"

After Chen Yuan thought for a while, he came to a conclusion.

Previously, Jupiter was moving outward, and the reason for moving outward was that four terrestrial planets were swallowed by Chen Yuan.

At that time, Chen Yuan stayed outside Jupiter, so Jupiter, which lost the gravitational force of the four terrestrial planets, naturally moved outward.

But now, Neptune, Uranus, and Saturn, which originally had gravitational effects on Jupiter, are gone.

Without the gravitational pull of the three gas giants, the gravitational pull of the four terrestrial planets is naturally greater.

Jupiter naturally moved inward.

And the planet of luck was also affected by the gravitational pull of the eight planets inside. When Chen Yuan left, he took away the mass of six planets. The planet of luck lacked the gravitational pull brought by these masses.

It naturally ran outward and was eventually thrown into interstellar space and became a wandering planet.

After figuring out what was going on.

Chen Yuan was a little depressed.

After all, the planet of luck is a planet with a larger volume and mass than Jupiter. He originally wanted to come back and swallow Jupiter and the planet of luck.

In this way, Chen Yuan can increase some mass and volume.

"If you want to become a star, you need at least 13 Jupiter masses. Then you can become a brown dwarf."

"My current mass is equal to three Jupiters. If you want to become a brown dwarf, you need to swallow 10 Jupiter masses."

Brown dwarfs are between the smallest star and the largest planet. They can't be called stars or planets, but if you want to become a star, you must first become a brown dwarf.

"Don't think about it, swallow Jupiter first."

Chen Yuan used his consciousness to control his body to get closer to Jupiter.

The appearance of Jupiter came into his eyes.

Just like Neptune, Uranus, and Saturn, Jupiter is also a gas giant planet.

Many people think that a gas giant planet is like a balloon.

But it's not.

Jupiter is mainly composed of hydrogen and nitrogen. It is indeed gaseous from the surface, but because of the pressure.

In the middle, the gas is crushed into liquid by pressure, and further inside, the hydrogen will be compressed into metal.

That is to say, whether it is Neptune, Uranus, Saturn or Jupiter, there are solids in between them.

It is just because the surface is gaseous, so it is called a gas giant planet.

And at this moment, Chen Yuan is already a gas giant planet like Jupiter.

His volume is only slightly larger than Jupiter, it can only be said that it is slightly larger.

And this slightly larger volume just meets the conditions for Chen Yuan to swallow Jupiter!

As usual, Chen Yuan first controlled his body to return to Jupiter's orbit.

Then approached Jupiter.

Because of the terrifying gravitational force.

The gas on Jupiter was pulled out by Chen Yuan's gravitational force, and part of Chen Yuan's gas was also pulled out by Jupiter's gravitational force.

As the two approached, the two gases connected together, looking like a bridge connecting the two planets.

Since Chen Yuan's mass is twice that of Jupiter, the gravitational force generated by Chen Yuan is greater than that generated by Jupiter.

The gas on Jupiter began to be deprived by Chen Yuan.

Now that the gases on the two bodies have come into contact, Chen Yuan can start to devour.

But Chen Yuan felt that the distance from Jupiter was too far now, and the devouring was too slow.

So, he chose to get closer.

As Chen Yuan approached, the gas on Jupiter escaped faster.

The terrifying gravitational force generated by Chen Yuan stripped the gas on Jupiter alive, and those gases were captured by Chen Yuan's gravitational force and swallowed by Chen Yuan.

Chen Yuan approached Jupiter.

The two spheres came into contact.

"Swallow!"

Accompanied by Chen Yuan's voice in his heart.

Jupiter turned into golden light.

The golden light flew towards Chen Yuan quickly.

Chen Yuan's volume was no longer increasing, but his mass and density were increasing crazily.

Because Chen Yuan's mass crushed Jupiter, this time the swallowing was much faster than when he swallowed Sirius B.

Jupiter disappeared completely.

The sun was the only one left in the solar system.

Chen Yuan was wrapped in golden light, which slowly dispersed.

Chen Yuan looked at his body.

"This... the volume is no longer increasing?"

Now Chen Yuan wanted to increase his volume, there was only one way.

That was to become a star.

Only by becoming a star could he continue to increase his volume.
