orbital

It has the shortest orbital period of any known comet within our solar system, taking just 3.3 years to orbit the Sun.

But however Skynet-1A then got shifted to its present position, it was ultimately allowed to die in an awkward place when really it should have been put in an "orbital graveyard".

Given its orbital path, the last time this comet would have been seen in the sky was about 80,000 years ago, during the time of the Neanderthals.

From mid-July to early September, the Earth’s orbital path around the sun crosses that of the comet.

In addition to biological contamination, they argue that guidelines should be expanded to address more than orbital debris, crowding, and security issues.
