Claim That Mars Is Closer Than It Has Been In 60,000-Years Is BAD Science — Worthy Of Trump.

by Anura Guruge


Click to ENLARGE & read. From ‘EarthSkyNews’.


Look at the claim (above) for 2003 & then for 2018 & today.

I am more than willing to admit that We & Mars are rather close together today. I also have NO problems making claims about closeness as long as we don’t go BEYOND 400-years. That is it.

All bets are OFF for distances prior to that. We just don’t know. We don’t have any measurements. We are still trying to nail down orbital distances, shapes & periods.

60,000-years ago. WE HAVE NO CLUE.

How & Where To See Comet, 45P, February 9 – 12, 2017, As It Makes Close Approach.

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.

comets


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.

Earth At Its Closest to Sun For ALL Of 2017 — Evening Of Wednesday, January 4.

by Anura Guruge


Click to ENLARGE.

perihelion


This happens, like clockwork, each and every year.

It has to do with the Earth’s orbit, around the Sun, being an ellipse (as is nearly all orbital paths in the Solar System). With any and all elliptical orbits you always have a closest and furthest point from the object being orbited. These are known (by the Latin) Perihelion & Aphelion.

Earth’s Perihelion with the Sun occurs in January. The Aphelion in July. In each case it is about 2 weeks after the last Solstice. This is how things are right now. Kind of a coincidence.

But it means that the Southern Hemisphere ALWAYS gets a bit closer to the Sun than the Northern. In other words, when the Northern Hemisphere is tilted towards the Sun, the Earth is at its furthest. C’est la vie.

Anywho. In 2017, Perihelion was on January 4th.

Think – Today: What Was The Basis For The Gallon?

by Anura Guruge


thinktodaybanner

gallon-of-waterIn the U.S. it is still (thankfully) the standard unit of measurement for gasoline (i.e., petrol), heating oil etc. How did we end up with the gallon? What was the basis for it as a unit for measuring the volume of liquids?


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


Yesterday’s ‘Think’: “What Is Under Your Feet, A Few Thousand Miles Down” — at all times, wherever you are, there will be be at least 7,900 miles of ‘earth’ BELOW you! That actually happens to be the diameter of the Earth, 7,917.5 miles to be exact. The interior of the Earth, as you must remember from somewhere, is layered — like an onion (albeit without too many layers). There is the topmost ‘crust’, the main crust per se, the mantle, the liquid outer core and then the extremely solid, inner core. It is worth looking up. Google it “earth’s interior”.

Think – Today: What Is Under Your Feet, A Few Thousand Miles Down?

by Anura Guruge


thinktodaybanner

feetHow often do you think about IT, i.e., what you are standing upon. Much of the time, we, at most, are only aware or thinking about, at most, the top 9″ of what we are standing upon. We tend to think of it as carpet, tile, road, grass, snow, sand, water etc. But, this is BUT the surface. What is underneath, directly underneath — thousands of miles down? Have you ever thought about that.


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


Yesterday’s ‘Think’: “General Tso’s Chicken” — the name and the dish per se are essentially American, albeit created by one or more Chinese chefs in the 1970s. It is believed to have been named after a statesman and military leader from the Hunan Province, Zuo Zongtang (also Tso Tsung-t’ang). However, the good General had no hand in coming up with this dish and would never have had eaten it — given that he died in 1884. His name was basically borrowed to give the dish some ‘character’!

That is pretty impressive. Olympus image stabilisation BUMPING against Earth’s rotation? WOW.

Talk about Laws of Physics.

Technologically, on PAPER, the Olympus OM-D E-M1 Mk II is one heck of a camera — but, alas, as yet, it is but a paper-tiger.

I am keeping an eye on this.

I want a camera that is limited by the Laws of Physics. That is TRUE bragging rights.

This “Global Warming” In New Hampshire, With 43F In June, Is Really Getting Very Old, Very Fast.

How anybody who lives in New Hampshire, and is not a total couch potato who never ventures out, can still believe in Global ‘bloody’ Warming defeats me.

It has been BLOODY cold in New Hampshire for the last 2 days — and those that know me, and know that I will still go running in 5°F weather, will know that IF I complain of it being cold, it is pretty serious.

This, my friend, is NOT right and there is no damn, frigging Global Warming in sight — at least not in frigid New Hampshire. I would LOVE some Global bloody Warming. I need to renew and top up my tan. Relying just on tanning creams becomes and expensive and messy hobby.

Yes, of course, we have seen Climate Change BUT that is because the DISTANCE of the Earth’s orbit, from the Sun, has changed! You did NOT know that did you? Most people don’t. Why, the Earth is getting lighter despite the increase in obese folks, worldwide. Yes, I need to write about this in detail — but I don’t have the time. It is the Earth’s weight, of MASS if you want to be pedantic and scientific, that is changing. Greenhouse Effect is NOTHING. It is the distance from the Sun that counts. Remember I do know my astronomy

Check these out. It is June 2nd and I am forced to wear sweats — though sweating is the last thing that is happening around here.

2000 EM26 Which Hopefully Streaked Past The Earth At A 2.1 Million Mile Separation Was NOT SPOTTED!

They set out to spot it, telescopically, in 2006 and 2009 and failed.

They failed again this year, i.e., 2014, though in astronomical terms, it was again close to Earth.

It has an orbital period around the Sun of 8.9 months.

Its perihelion is at 0.43 AU while its aphelion is at 1.2 AU. As the orbital diagram to the right shows, it is in a tight, compact orbit, around the Sun, that takes it a bit further out than the orbit of Earth and stays outside the orbit of Mercury.

IF it is still there we will continue to have close, but not fatal, encounters on a regular basis for centuries to come. Its orbit might start to get degraded by then with the repeated gravitational interplays with Earth.

Too much should not be read into it not being spotted this year. It is very small and dark [i.e., dim — in that it doesn’t reflect much sunlight]. Yes, it could have disintegrated or got nudged into another orbit. In the case of the later it would be useful to spot it again. Possible that it has been spotted as a different asteroid. That can happen. As I have said for the last 18 months it is NOT the asterids that we KNOW about that we need to be worried about. None of them, and forget Government conspiracies, is set to hit us. It is the ones that we don’t know about that pose the risks.
