How do scientists guide space probes?

Answer 1

Space probes are guided by complex computer models.

Complex polynomial equations derived from astronomical data sets can be used to calculate the positions of the Sun, Moon, and other planets; the most up-to-date useful data is NASA's DE430 data.

In order to enable the satellite to reach Pluto, the data was altered for the Horizons mission, which enhanced the model of Pluto's orbit.

The information includes terms for polynomial equations from J2000 through 2001-01-01 12:00:00, expressed in Julian centuries.

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.
