Probably, but nobody cares.
The problem is that at 30AU from the Sun, the difference between "sunlight" and "shadow" isn't all that great. And there's nobody on Neptune (or at least, nobody we know of) to notice, it isn't all that important.
On earth there are 2 eclipses, Lunar and Solar eclipses

On average, we can expect two lunar eclipses and two solar eclipses in any year. 2010 will have four eclipses, right on the average.
Pluto has a highly eccentric orbit - it's orbital eccentricity is equal to about 0.2488. As a consequence, during parts of it's orbit around the sun, Pluto eclipses Neptune's orbit, making it closer to the sun than Neptune. The last time Pluto was closer to the sun than Neptune was between February 7, 1979 and February 11, 1999.
The answer very much depends on the year. One calendar year has a minimum of four eclipses, which are two solar eclipses and two lunar eclipses. A year can have as many as seven eclipses. So each year is different.
Solar and lunar eclipses
Canon of Eclipses was created in 1887.
Eclipses were not discovered. They are a natural occurring event.
Solar eclipses are more common than lunar eclipses.
Yes, these are called partial eclipses.
yes they do
Creative Eclipses was created in 1998-11.
