Comet P45 where to see

For North America.


45pposition


Though it will be close, it is NOT a very big comet. Plus, being a PERIODIC that goes around the Sun once every 5.25 years, and has been doing so for a long time, it has expended some/much of its frozen ices that vaporize to create the tail. So it will NOT be putting on a dazzling show. If anything it will JUST (and I mean JUST) be naked eye visible. Best to try and see it with a telescope or a pair of binoculars.

Comet, 45P, Will Make 17th Closest (Known) Earth-Comet Encounter On February 11, 2017.

Nothing to get too excited about. For a start, this same comet, 45P (where the ‘P’ indicates that it is ‘periodic’), flew by, even closer in 2011.

7.72 million mile separation is pretty respectable — 32x GREATER than the distance to the Moon.

So, don’t panic. Plus, it is quite a small comet, maybe a MILE across, max.

You may hear in the media that this the 8th closest approach by a comet. That is 8th closest as of 1950s when we really got good at measuring these distances — and you have to ALWAYS add, ‘KNOWN’.

This comet, 45P, even at this distance is unlikely to be naked eye visible!

So think of all the comet flybys our ancestors would have been oblivious to.

Also remember we are talking comets. Asteroids routinely whiz by much closer — as say did 2000EM26 in February 2014, with just 2.1 million mile separation.

Think – Today: Is There A Difference Between Celibacy & Chastity?

by Anura Guruge

95935-92479You hear ‘celibacy’, these days, more often than ‘chasity’. And there certainly is no ‘celibacy belt’ as opposed to the chastity one. Do they two words have different meanings or are they synonyms?


Think first, then research, then THINK again. Think for the pleasure of thinking.


Yesterday’s ‘Think’: “Light by which we see the planets” — We see the planets (in our solar system), comets (and for that matter asteroids and other minor planets, albeit not naked eye) thanks to the reflected light from our Sun. None of the planets, comets or for that matter any of the other bodies in our Solar System generate any light bright enough to be seen from Earth, naked eye. Any light that they produce would be due to volcanic activity (or equivalent), burning gases and lightning storms. None of that produces enough light to be seen by us. So, everything we see in the Solar System is due to reflected sunlight. That is worth reflecting on.

Think – Today: What Is The Light That Makes It Possible For Us To See The Planets & Comets?

by Anura Guruge

nov5conjunctionWe have all seen Venus, reddish Mars, Bright Jupiter and Saturn in the night sky. If you are lucky (and old enough) you may have seen a comet or two. What makes it possible for us to see, naked eye, these planets and comets?


Think first, then research, then THINK again. Think for the pleasure of thinking.


Yesterday’s ‘Think’: “Natural food that doesn’t spoil” — Honey! Pots of honey were found in Egypt’s famous pyramids and though they were at least 3,000 years old the honey was not spoilt and was perfectly edible. Honey is considered to be a food that does not spoil. Honey, however, can contain spores that could be harmful. Most people, once they are 1-year or older, have developed sufficient enough ‘immunity’ in their digestive tract to nullify anything bad in these spores. Not so in babies. So that is the only caveat. The 1-year rule.

Think – Today: Why Is It Called ‘Monday’?

Have you ever wondered why ‘Monday’ is ‘Monday’?


Think first, then research, then THINK again. Think for the pleasure of thinking.


Yesterday’s ‘Think’Meteor showers occur when Earth enters debris trails left behind by comets, typically periodic comets such as Haley’s. The Meteors are small particles of debris burning up as they cross the Earth’s atmosphere.

“Brain Meditation” Book #9 In “Meditation” Category At Amazon — Albeit For FREE Books!

by Anura Guruge


no9free

Click to ENLARGE and gaze at in amazement.


I have been here before. I got #1 in “Astronomy” in August 2013 when I made my “Comets: 101 Facts & Trivia” for FREE, for a week.

I find it amazing. The Comet book was 99 cent and “Brain Meditation” is $2.00.

People won’t pay the 99 cents or $2 but are more than HAPPY to take it if it is FREE.

Yes, I do appreciate that there are folks that do not have Credit Cards and as such cannot buy things at Amazon. I sympathize.

But, to I, as an author this is kind of sad …

But it is OK. As long as people get to READ IT and hopefully tell others.

99 cents!

$2!
