a. Earth's orbit would not change.
Explanation:
The force that keeps the Earth in circular motion around the Sun is the gravitational force between the Earth and the Sun, whose magnitude is given by:
where
is the gravitational constant
m is the mass of the Earth
M is the mass of the Sun
r is the distance between them
From the equation, we observe that this force depends only on three factors:
- the mass of the Earth
- the mass of the Sun
- their separation
If the Sun is replaced by a black hole of the same mass, none of these factors would change (the central mass M would remain the same), therefore the gravitational force F would not change, and therefore the orbit of the Earth would not change.

The eccentricity of its orbit is
- Mass is a physical body's total amount of matter. It also serves as a gauge for the body's inertia or resistance to acceleration (change in velocity) in the presence of a net force. The strength of an object's gravitational pull to other bodies is also influenced by its mass.
- The kilogram is the SI unit of mass (kg). In science and technology, a body's weight in a given reference frame is the force that causes it to accelerate at a rate equal to the local acceleration of free fall in that frame.
- For instance, a kilogram mass weighs around 2.2 pounds at the surface of the planet. However, the same kilogram mass would weigh just about 0.8 pounds on Mars and about 5.5 pounds on Jupiter.
- An object's mass is a crucial indicator of how much stuff it contains. Weight is a measurement of an object's gravitational pull. It is influenced by the object's location in addition to its mass. As a result, weight is a measurement of force.
The length of the semi-major axis is calculated as follows:
