*Here are some useful calculations about pixels width and height in Miles, Meters, etc.*

*Here, we have:*

d = R * tan(h)

Where:

**d*** is the distance in length units, such as Sun-Pluto, or miles.*

**R*** is the distance between PX and Earth, same units as d.*

**h*** is the angel in degrees at Earth side.*

*Since each frame is 1024*1024 pixels, and the field of view is 23.6*23.6 Arcminutes, each pixel represents 3.8411458333333e-4
Degrees.*

*Assuming that PX is at 3 SunPluto,*

*Given:*

*R = 3 SunPluto*

h = 3.8411458333333e-4 Degrees

AU = 1.496e11 Meters

SunPluto = 39.91136 AU = 5.970739456e12 Meters = 3.71004549431e+9 Miles

EarthMoonDistance = 3.844e8 Meters

*Pixel Size:*

*d = R * tan(h)
= 3 * tan(3.8411458333333e-4)
= 2.0112192552579e-5 SunPluto
= 8.0270495735532e-4 AU
= 1.2008466162035e+8 Meters
= 120084.66162035 KM
= 74617.149360458097 Miles
= 0.312395 EarthMoonDistance*
