A newfound comet is about to loop around the Sun and might offer skywatchers a rare and fantastic view. But comets are unpredictable, and this one has a wide range of possible outcomes, experts say.
When Australian astronomer Robert McNaught announced Aug. 7 that he had discovered a faint comet on a photograph taken at the Siding Spring Observatory in New South Wales, it was a distant and inconspicuous object. But its orbital motion at once made it clear that this comet, officially catalogued as C/2006 P1, might grow very bright right about now.
Comet McNaught's orbit [video] indicates that it will sweep to within just 15.8 million miles (25.4 million kilometers) of the Sun on Jan. 12. This rather close approach—less than half the average distance of Mercury, the closest planet to the Sun—suggests the comet has the potential to briefly evolve into a bright object. The big question is, just how bright?
