Comet of the century ISON is finally visible to naked eye - but will it be visible in daylight as originally predicted? Also known as C/2012 S1, the comet was discovered in September last year, but has been journeying towards the inner solar system for at least a million years, originating in the distant Oort cloud, at the edge of our solar system. On 28 November, it will make its closest approach to the sun, just 1.2 million kilometres above the solar surface.
