Imagine that our Sun were magically and suddenly replaced by a black hole of the same mass (1 solar mass). What would happen to Earth in its orbit?

Question

Quizplus · Accepted Answer

Earth's orbit is determined by the gravitational force of the Sun, which is not affected by whether the Sun is a normal star or a black hole. As long as the mass of the object at the center of the solar system remains the same, Earth's orbit would remain the same. Additionally, the mass of the black hole would be the same as the previous mass of the Sun, meaning that the total gravitational force acting on Earth would be unchanged as well.
