Scientists were expecting quite a show. A new study suggests the comet actually broke up before reaching the sun.
What happened as Comet ISON passed the Sun?

What is Comet ISON’s distance from the Sun?
Comet ISON came to perihelion (closest approach to the Sun) on 28 November 2013 at a distance of 0.0124 AU (1,860,000 km; 1,150,000 mi) from the center point of the Sun. Accounting for the solar radius of 695,500 km (432,200 mi), Comet ISON passed approximately 1,165,000 km (724,000 mi) above the Sun’s surface.
