What if Earth had the Sun's gravity and mass?

If the Earth had the same gravity and mass as the Sun, the solar system would look very different.<br><br>Firstly, the Earth would be the center of the solar system, and the Sun would be one of the planets orbiting it. This is because the mass of the Earth would be much larger than that of the Sun, so it would have a stronger gravitational pull. The other planets would then orbit one of the two.<br><br>The most likely scenario is that the other planets would be left orbiting the Sun, and the two would be orbiting each other. This is because the Sun already has a larger mass than the other planets, so it would be able to hold onto them even if the Earth had the same mass as it. As a result, the solar system would look more like a binary star system, with two central bodies orbiting each other.<br><br>If that happened, the closest of the planets orbiting each of them would likely be the gas giants, Uranus and Neptune on the one hand and Saturn and Jupiter on the other. This is because they have the strongest gravitational pull of all the planets, so they would be able to hold onto their moons even if the Earth had the same mass as the Sun.
