  No. 12 - Summer 2004: Comet or Asteroid?
Another possibility is that 133P is a true asteroid, as its orbit suggests, but one in which ice has for some reason been exposed on the surface.
Scientific interest in 133P lies partly in the ambiguity of its true nature, but also in the possible implications for the comets and asteroids.
Sometimes, as in the (so far) unique case of 133P, ice near the surface is heated and produces a dusty trail.

 133P/(7968) Elst-Pizarro = P/1996 N2 (Elst-Pizarro)
The orbit has a very low inclination (1.4 degrees) and the distance from the Sun varies from 2.63AU at perihelion to 3.69AU at aphelion, thus there is nothing in the orbit to make it look in any way unusual.
1996, three months after perihelion, Eric Elst and Guido Pizarro, detected a faint tail and also noted that the “asteroid” was 2-3 magnitudes brighter than usual, although no coma was present.
The comet passed perihelion again at the end of November 2001 and again, several months after perihelion a tail was detected, although it was much fainter and any photometric outburst had an amplitude of less than one magnitude.

But in 1996 a new photograph by the European Southern Observatory's Guido Pizarro showed the 18th-magnitude object accompanied by a slender tail, leading astronomer Eric Elst of Belgium's Royal Observatory to classify it as a comet.
The problem lies with the orbit of the supposed comet, which is entirely within the main asteroid belt between Mars and Jupiter.
Astronomer Imre Toth of Hungary's Kolkony Observatory offered an alternative explanation, proposing that the tail recorded on Pizarro's photograph was the result of an impact on the surface of an asteroid that ejected dust into space.

 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.

However, some intermediate objects have recently been discovered which seem to possess properties that are typical of both categories (asteroid-comet).
On August 7, 1996 Eric W. Elst discovered an interesting intermediate object on exposures from July 14, 1996 taken by Guido Pizarro with the 1.0-m Schmidt telescope at the ESO, La Silla (Elst and Pizarro 1996).
This object surprisingly showed a cometary tail and was designated as P/1996 N2 (Elst-Pizarro) (133P/Elst-Pizarro or 7968 Elst-Pizarro), while moving in a typical asteroidal orbit in the main belt of the minor planets.
