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.

What was the name of the comet in 2013?

In case you missed it, there was some hullabaloo in the astronomy sector in 2013 around Comet ISON, but for those of us who are less astronomically inclined the reason for this excitement is often overlooked. Formally known as C/2012 S1 the Comet ISON could have made history by being the brightest comet that Earth has ever seen.

When does Comet ISON pass the frost line?

Sometime in late July or early August, the comet will pass what’s called the frost line, some 230 to 280 million miles away from the sun, when it will feel enough radiation from the sun that water will begin to evaporate and the comet will appear brighter.

How big is the solar radius of Comet ISON?

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. Its trajectory appeared to be hyperbolic, which suggested that it was a dynamically new comet coming freshly from the Oort cloud or even a candidate interstellar comet.
