!Solar/Describe/Pluto

This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.

Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

Pluto is usually the furthest planet from the Sun, but due to its 
highly elliptical orbit, it is sometimes closer than the planet 
Neptune. It is easily the smallest planet, only half the size 
of Mercury. It is also a rocky planet, unlike it nearest 
neighbours and due to its extreme distance from the Sun, the 
surface temperature is only -230 degrees C. Pluto has one known 
satellite, Charon, which with a diameter of 1,199km is nearly 
half the size of Pluto.

Little else is known about Pluto, as it currently remains the 
only planet in the solar system, not visited by spacecraft from 
Earth.
