I am impressed with 2 items in this article.

The 1st is a hyperbolic retrograde orbit, which implies a possible origin from outside the oort cloud; (may be an interstellar comet).

The other bit of info is the diameter of the nucleus (50Km) the spectacular classic comet Hale Bopp had a 60Km nucleus and developed a coma as large as the sun.

Will definitely be interesting to watch but if a collision is definite: it will delete all the mars exploration programmes (inc. the ones already there) for a century or so as the mess in orbit will turn most space hardware into facsimiles of Beirut in the 1980s civil war (which tends not to make it work so well).

Have a nice day: Ag
