Comettesti

Comettesti is a term used in astronomy to describe a framework for evaluating whether a Solar System body displays comet-like activity. It refers to a set of diagnostic tests that combine observational data and orbital analysis to classify objects along a continuum from dormant asteroids to active comets. The term is a portmanteau of 'comet' and 'test' and has appeared chiefly in informal discussions and some science communication materials rather than as an official taxonomic category.

In practice, a comettesti assessment would consider indicators such as the presence of a coma or tail, spectroscopic evidence of gas emission, measurements of dust production, and any measurable non-gravitational forces on the object's orbit. Morphological properties, such as activity-driven changes in brightness, and physical characteristics like albedo and activity history, may also be integrated into a composite score or decision framework. The aim is to help researchers distinguish genuine cometary activity from transient or instrumental phenomena, and to inform survey strategies and mission planning for objects near the asteroid–comet boundary.

As a concept, comettesti is not universally adopted as an official classification. It is best described as a heuristic or discussion tool that highlights the spectrum of activity among small Solar System bodies. See also comets, active asteroids, main-belt comets, and dormant comets.
