How is the distance between earth and pluto calculated?

Answer 1

For identifiable non-star space bodies, powerful radio signals are sent and we await their return as echo. The distance is
(the interval of time in between) X (speed of light)/2

The parallax method is utilized to calculate distances for stars. For other

recognizable space bodies, strong radio signals are transmitted and received.

The space body's distance from us is, their return as echo.

(the amount of time between) X (light speed)/2.

Explanation using illustrative data:

The total time that strong radio signals travel to and from Pluto from Earth is

38400 s = 10 h 40 m.

The separation is

(38400 s X 299792 km.s)/2 km = approximately 5756 million km.

The distance between Earth and Pluto is calculated using astronomical techniques such as radar ranging, parallax measurements, and observations of Pluto's position relative to background stars. These methods allow astronomers to determine the distance between Earth and Pluto with high precision.

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.
