find the moment of inertia of the earth. Radius is 6,000 km and mass is 6 x 10^24 kg
moment of inertia about its spinning axis, or moment of inertia about its Sun orbital point?

To find the moment of inertia of the Earth, we need to know its mass and how that mass is distributed with respect to its axis of rotation. The moment of inertia is a measure of an object's resistance to rotational motion and is calculated using the formula:
I = M * R^2
where I is the moment of inertia, M is the mass of the object, and R is the distance from the axis of rotation.
In this case, the Earth can be approximated as a uniform sphere, where the mass is distributed evenly. Given that the mass of the Earth is 6 x 10^24 kg and the radius is 6,000 km (which we need to convert to meters), we can use these values to calculate the moment of inertia.
First, let's convert the radius from kilometers to meters:
Radius = 6,000 km = 6,000,000 m
Now, we can calculate the moment of inertia using the formula:
I = M * R^2
Plugging in the values, we have:
I = (6 x 10^24 kg) * (6,000,000 m)^2
Calculating this will give us the moment of inertia of the Earth.
