The appromiate mass of a comet X has been memasured. When comet X orbits the Sun 5000 years later it only has half it's previous mass.
Approximately how many orbits of the Sun has the comet completed and what is the period of the comets orbit?
More information is needed to answer that. The mass loss per orbit depends upon how close it comes to the sun, what it is made of, and the period of the orbit.

To calculate the number of orbits completed by the comet and the period of its orbit, we can follow these steps:
Step 1: Find the rate of mass loss per orbit.
Given that the comet's mass is halved after 5000 years, we can calculate the rate of mass loss per orbit by dividing the mass loss (initial mass minus final mass) by the number of orbits it took to lose that mass. Let's denote the initial mass as M_initial and the final mass as M_final.
Rate of mass loss per orbit = (M_initial - M_final) / Number of orbits
Step 2: Calculate the number of orbits completed.
Since we know the rate of mass loss per orbit, we can determine the number of orbits the comet has completed by dividing the initial mass loss by the rate of mass loss per orbit.
Number of orbits = Initial mass loss / Rate of mass loss per orbit
Step 3: Calculate the period of the comet's orbit.
To find the period of the comet's orbit, we divide the total time elapsed (5000 years) by the number of orbits completed.
Period = Total time elapsed / Number of orbits
By using the above steps, you can determine the approximate number of orbits completed and the period of the comet's orbit.
