Sirius migration time

As we all know, the earth is a planet. Sirius is a star, and its diameter is 185 times that of the earth (the diameter of the sun is 109 times that of the earth). What kind of experience would it be if the earth became as big as Sirius overnight?

The star below Orion is Sirius, which is clearly visible in winter.

If the density of the earth remains unchanged, its mass will be 636,000 times that of the present (the weight of the sun is 330,000 times that of the earth). Bigger than the sun. At this time, the gravity of the earth's surface will be 58 times that of the present, and the gravity of the sun's surface will be only 28 times that of the earth's surface, because the gravity of the earth at this time is greater than that of the sun, and the solar system will be renamed? Earth system? Whoever has a large mass is the king of gravity! Then eudoxus's geocentric theory will become a reality.

Geocentric model of eudoxus's imagination

Renaming is a trivial matter, but I'm afraid the game has not been renamed yet. You know, the gravity of the earth has reached 50 times overnight, and the human body will not be able to adapt to the strong gravity.

In addition, the mass of Jupiter, the largest of the eight planets, is 3 18 times that of the earth. There is an upper limit to the mass of the planet, which is 13 Jupiter mass, and then there is the brown dwarf (brown dwarf is a sub-stellar object, which can also trigger nuclear fusion and emit light, but the light is extremely weak. When the brown dwarf reaches 80 times the mass of Jupiter, it will trigger nuclear fusion and become a star. The mass of the sun is 1048 times that of Jupiter. Now the earth is bigger than the sun, so it will become a shining star. The surface temperature will be higher than the sun, and then what? Earth system? It will become a binary star system, and the earth and the sun will revolve around each other.

Besides, if humans immigrated to Sirius according to the present situation, how much would you weigh, not to mention the role of gravity? I'm afraid that what I didn't do was crushed to death by my own weight. Therefore, although the planet is big, there is no happiness.
