S-ar putea ca aceasta cometa descoperita recent (cu un arc observational inca foarte scurt) sa fie prima cometa interstelara. Probabil va fi foarte bine urmarita atat de amatori cat si de profesionisti in viitorul apropiat asa ca vom afla in curand.

"Further observations of this object are very much desired.  Unless there
are serious problems with much of the astrometry listed below, strongly
hyperbolic orbits are the only viable solutions.  Although it is probably
not too sensible to compute meaningful original and future barycentric orbits,
given the very short arc of observations, the orbit below has e ~ 1.2 for
both values.  If further observations confirm the unusual nature of this
orbit, this object may be the first clear case of an interstellar comet."
