Comet ISON prospects, quite literally, are getting brighter by the day.
It is intact and is becoming more ‘active’, i.e., spewing out more gas and dust which is what leads to the coma and tail, by the minute.
Right now it is travelling at more than 10 miles PER SECOND. That is in excess of 38,000 miles per hours. So it is getting closer to the Sun at a very fast clip.
Ameteur astronomers using backyard telescopes are capturing some amazing pictures. Check this one from October 5, from Austria (that is in Europe).
On November 2, 2013, i.e., next week, it will cross Earth’s orbit for the first time, i.e., inbound (towards Sun) crossing. Check this post for orbital diagram.
But, on that day Earth is way off to the right — 112 MILLION miles away, that is 1.2 x the Earth-Sun distance.
So, we will not be able to see Comet ISON, naked eye, on November 2.
The EARLIEST possibility for a potential glimpse is November 17 — some of this also having to do with moonlight getting in the way.
Closer to the 17th, as things become more clear, I will post an update.
It might not be the ‘Comet of the Century’, but it is still on track to be one heck of a comet.
