As with all things that orbit the Sun, the speed of Comet ISON, C/2012 S1, has to increase as it gets closer to the Sun. Keplerian laws of orbital physics etc. etc. So, I just did the above spreadsheet just to work out what those speeds will be. 225,750 mph is fast, but comets can go faster!

I didn’t go beyond perihelion since we don’t know what might happen following the sungrazing. Easy enough for me to extend it. Hope you like this.
