Comet 'Hal Bot'

Comet hal bot was discovered at a distance of over seven astronomical units, where one unit equals 93 million miles. Only those with the right equipment and keen interest in astronomy would be able to observe it for quite a while. They're spinning theire, giving off gas and dust from only restricted areas on their nucleus. Depending on the spin axis, they can decide to just point themselves away from us when they get close to the sun.
