Does it take a longer, same, or shorter time to measure a parallactic shift from Pluto as compared to the Earth? Why?

Answer 1

It will take longer from Pluto than from Earth. In its irbit around the Sun, Pluto moves much more slowly than the Earth.

Because Pluto is further from the Sun than Earth, it can theoretically measure parallax for a much wider range of stars; however, it would take more than a century to traverse that range (i.e., turn the orbit 180 degrees) and observe the full parallax effect from Pluto.

Answer 2

It takes a longer time to measure a parallactic shift from Pluto compared to Earth because Pluto's orbit is much larger than Earth's, resulting in a smaller baseline for measuring the shift.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
