What is pluto minimum distance from earth?
With due consideration of the high inclination
I have used NASA Planetary Fact Sheet data.
Pluto : Perihelion = 4.436 billion (B) km and orbital inclination to Earth's orbital plane =
Earth : Aphelion: 0.1521 B km.
For least possible Earth-Pluto distance,,in the Earth (E) - Sun (S) - Pluto (P)
SE = Earth aphelion, SP = Pluto perihelion and
This simplifies to 4.29 B km
