Pluto takes 6 days and 9 hours to complete one rotation, so this is how long a day is on Pluto.

You can also look through these books from Amazon.com if you want more information about Pluto.

One interesting note is that Pluto’s moon Charon is tidally locked around Pluto. This means that Charon takes 6 days and 9 hours to orbit around Pluto – the same amount of time it takes for a day on Pluto. This means that Charon is always at the same place in the sky when seen from Pluto.

You would have the same view from Charon as well. From some vantage points on Charon, Pluto would always hang at the same spot in the sky, and for other parts, you wouldn’t be able to see Pluto at all.
