- *Pluto's Moon: Charon
Charon is unusual in that it is the largest moon with respect to its primary planet in the Solar System (a distinction once held by Earth's Moon). Some prefer to think of Pluto/Charon as a double planet rather than a planet and a moon.

- Clyde Tombaugh
On January 17, 1997, Clyde Tombaugh, the discoverer of the planet Pluto, passed away. In his nearly 91 years Tombaugh made tremendous contributions to the field of astronomy and inspired generations of future astronomers to follow in his footsteps. This Web site is dedicated to the memory of Clyde Tombaugh.

- Discovery of Pluto
Many papers have been written and published on the triumphal detection and discovery of Pluto. Clyde Tombaugh relates the "down mood" and emotions experienced by those persons involved.

- General Features of Pluto
Pluto is on a highly elliptical orbit at an average separation of almost 40 A. U. from the Sun, with an orbital period of 248 years. Since the planet was only discovered in 1930, we have observed only a portion of its orbit so far.

- Is Pluto a planet? Yes!
Is Pluto really a planet? That's what astronomers have been discussing since late last year when some members of the International Astronomical Union suggested that Pluto be given a minor planet designation. Why? For one thing Pluto is very small. It's 6 times smaller than Earth, and even smaller than seven of the solar system's moons (the Moon, Io, Europa, Ganymede, Callisto, Titan and Triton).

- Pluto's Moon Charon
In 1978, careful Earth-based observation indicated that the image of Pluto had a slight bulge. This was interpreted as evidence for a previously unknown moon, named Charon.
