  133P/Elst-Pizarro - Wikipedia, the free encyclopedia
It is unremarkable, but for the fact that it is also designated an asteroid, 7968 Elst-Pizarro.
The orbit remains entirely within the orbits of Mars and Jupiter, with eccentricity 0.165, typical of a minor planet in the asteroid belt.
However, the images taken by Eric W. Elst and Guido Pizarro in 1996, when it was near perihelion, clearly show a cometary tail.

 Citapla
This minor planet, named on the occasion of the 100th anniversary of the founding of the University of Sofia, of wich he is considered the patron, is testament to Ohridski’s influence on Bulgarian science and culture.
Named in honor of Guido and Oscar Pizarro, who operate the 1-m Schmidt telescope and who exposed the plates on which this minor planet was discovered.
Named in honor of Elisabeth Völk (1946-), secretary at the European Southern Observatory’s headquarters in Garching, where she is chiefly responsible for the administration of the ESO Schmidt plates.

 Eric Walter Elst -- Facts, Info, and Encyclopedia article   (Site not responding. Last check: 2007-10-18)
Eric Walter Elst is a Belgian (A physicist who studies astronomy) astronomer.
He is a prolific discoverer of (Any of numerous small celestial bodies composed of rock and metal that move around the sun (mainly between the orbits of Mars and Jupiter)) asteroids, with nearly 3000 discovered so far (with about 40 of these having a co-discoverer).
The (Any of numerous small celestial bodies composed of rock and metal that move around the sun (mainly between the orbits of Mars and Jupiter)) asteroid 3936 Elst was named in his honour.

The clue to solve the enigma of the outburst activity seems to be the impact-induced activity of 7968 Elst-Pizarro, finding the parent body of the projectile or projectiles being responsible for generating the temporary activity colliding with the target body as supported by Boehnhardt (1997a) and Lien (1998).
The time interval from June 1 to August 1, 1996 was chosen to calculate the heliocentric ecliptic coordinates of the selected objects because this interval was the critical for the events generating the activity of Elst-Pizarro.
The first five objects found with orbits close to 7968 Elst-Pizarro are listed in Table 1 and their locations are displayed in the time interval (Fig.

 Henry Hsieh - 133P/Elst-Pizarro
These orbits also tend to be more highly inclined than that of most main belt asteroids.
EP was discovered in 1979 as a perfectly ordinary main belt asteroid (with a prototypically low eccentricity and low inclination) and was largely ignored until 1996 when Eric Elst and Guido Pizarro serendipitously discovered a long thin dust trail emanating from the object.
Analysis of this and further observations of the trail revealed that the dust had likely been emanating from EP for many months, making it difficult to explain the activity as a consequence of a simple impact.

Unfortunately, many of the articles that have appeared in the press have accidentally (or deliberately) misinterpreted this issue.
As with (2060) = 95P/Chiron, (4015) = 107P/Wilson-Harrington and (7968) = 133P/Elst-Pizarro, where the choice of "minor planet" or "comet" designation depends on the context, we are proposing that Pluto would have dual status as a "major" and a "minor" body.
Readers of these Circulars, in particular, will appreciate that Pluto is sufficiently fainter than the other major planets that it can be confused with many other minor planets.

 2 Possible impactor parent bodies   (Site not responding. Last check: 2007-10-18)
To find the orbits of the possible parent bodies of impactors a computer search method was used.
It had already been applied earlier revealing the possible parent body of the impactors to generate a probable impact-induced activity of the 7968 Elst-Pizarro (Toth 2000).
The minimum distances between the orbits of C/1999 S4 (LINEAR) and all other small bodies were calculated.
