Question

How many light years away is the sun from Pluto?

Answer 1

Hint: Light is a self-perpetuating electromagnetic wave whose strength weakens with the distance it travels.
A light-year is basically, the astronomical distance which refers to the distance traversed by light in a year.

Complete answer: Pluto is 32.9 AU away from the earth which implies 32.9 times 8 light minutes away from us. Therefore, Pluto is 263.2 light minutes away from the earth. In order to examine Pluto using radio waves it would take 263.2 minutes today, if the probe was as far as Pluto. A return signal would take just as long but that relies on the distance being the same.
There are 527,942 minutes in a year and Pluto is approximately 1/2007th of a light year away, today, which is just a small fraction of a light year. Due to its small size, it was not discovered until 1930.

Note: -Pluto was discovered by Clyde W. Tombaugh on February 18th, 1930.
- The Hubble Space Telescope of NASA has indicated that Pluto's crust could comprise complex organic molecules.
- Tombaugh Region is a unique feature of Pluto's surface, which is a heart-shaped region.
