Did You Know That ‘AOC’, Alexandria Ocasio-Cortez, Has An Asteroid Named After Her?

by Anura Guruge


Donald Trump will be SO, SO livid IF he ever finds out.

So don’t tell him. OK? Our secret.

This wasn’t recent either! It was named after her c. 2007 — eleven years ahead of her being elected to the United States House of Representatives.

This is pretty impressive stuff. She got this honor, because as a high school senior (aged 18), from Yorktown High School [Yorktown Heights, New York], in 2007, she won second place in the 2007 ‘Intel International Science and Engineering Fair’ for her microbiology project. Wow.

I really don’t know much about her. Did not even suspect this.

Trump will now want Jupiter renamed after him. But, maybe NOT Jupiter. Mars would be more appropriate and it is a GOOD COLOR match.


The asteroid itself had been discovered in 2000 at the Lincoln Laboratory.

A pretty common or garden asteroid in the asteroid belt. Nothing special. Decent size. Just over a mile across. So, not huge, but not tiny either.

A ‘Big Bad’ Collision In The Asteroid Belt In November 2018?

Wow. We know that collisions are not uncommon in the Asteroid Belt and much of what we find in that clutter of rocks is the aftermath of millions, if not billions, of collisions going back at least a couple of billion years. We just never get to see them. Asteroids are small.

Well, this looks like the aftermath of one heck of a collision. Check it out. Interesting.

JPL Small-Body Database Browser Has A New NON-Java ‘Orbit Diagram’ Viewer.

by Anura Guruge


Click to ENLARGE.

The announcement in ‘small type’.


In action. In this case with the 2018 GE3 asteroid that came very close to Earth on Sunday — with no warning at ALL.


I discovered this, to my utter joy, yesterday, when I was researching the rogue asteroid, 2018 GE3, that whizzed past Earth on Sunday with nary a notice. You can see the orbital diagram for that above, in the NEW orbital viewer.

It is NOT Java-based. That is so, so good. Running Java applets had become such a pain — with Web browsers, like Chrome, quite rightly, obsessing about the security vulnerabilities.

I had more or less stopped using the JPL Small-Body Database because the orbital viewer no longer worked.

And then … BINGO. Voila!

It is brilliant. Very nifty and has a built in screenshot capture as well as full-screen mode. You couldn’t ask for more.

Thank YOU, JPL. Good use of our taxpayer dollars.

The Rogue ~300′ Asteroid That Came Way Too Close To Earth Yesterday, April 15, 2018!

by Anura Guruge


Click to ENLARGE.


Click to ENLARGE and read here. Wikipedia: en.wikipedia.org/wiki/2018_GE3


It could have been a heyday for the Nibiru freaks who are hoping (yet again) for a ‘pie in the skyEarth collision on April 23, 2018.

This was 8 days early.

We (and that I mean the ‘Catalina Sky Survey‘ in Tucson, Arizona) only discovered it 24-hours prior to that! Yes, you read that right. It came straight out of the blue just 24-hours before whizzing by us. I have always claimed that this is the problem we will have with asteroids and comets. What we have to worry about are the ones that sneak up upon us like this one.

NO WARNING!

It was pretty big. Around the same size as the meteoroid that exploded above Tunguska, Russia in June 1908. If this had hit Earth, or exploded in the atmosphere, it would NOT have wiped us all out. But, it would have caused a huge amount of devastation.

As it says above: “It is the largest known asteroid to ever pass that close to Earth in observational history!

A/2017 U1 — Too Speculative To Claim That It Is ‘Interstellar’.

by Anura Guruge


Click to ENLARGE. From NASA/JPL @ http://www.jpl.nasa.gov.


Click to ENLARGE. Wikipedia: en.wikipedia.org/wiki/A/2017_U1


Definitely extremely interesting and intriguing. Wow. Orbital eccentricity of 1.1922! The greatest we have ever seen — the keywords here being ‘ever seen’. Comet ISON, that crashed and burned on Thanksgiving Day 2013 had an eccentricity of 1.0000015.

But, here is the deal with eccentricity. Anything over 1.0 means that the object will eventually leave our Solar System. That we know. But, what we cannot tell as yet is WHEN A/2017 U1 got that highly eccentric orbit. We just do NOT know — as yet. And maybe never will.

To claim that it must have originated OUTSIDE of our Solar System — is speculative. We do NOT have enough evidence.

NASA/JPL’s official statement confirms that: “So far, everything indicates this is likely an interstellar object, but more data would help to confirm it.” Note the ‘likely‘ and the part about ‘more data … for confirmation‘. That is exactly MY POINT and what I am trying to impress.

The claim that its orbit was NOT influenced by a close encounter with a planet — typically one of the BIG ones — is speculative. It could have been majorly torqued around by Uranus or Neptune. We don’t know.

I have a druthers that this is a very old comet — a periodic one at that, which on its last trip out, maybe 400 years ago got too close to a gas giant and had its orbit turned ‘upside down’.

We don’t know.

All I am stressing is do NOT jump to conclusions.

We know so little about what has happened in OUR Solar System and what is happening right now.

But, it is exciting.


Has a ton of good information about comets.

22 Books On A Shelf.

by Anura Guruge


Click to ENLARGE.


Why 22 and not 25?

Four of my books are in Kindle only — 3 about popes and one about “4 Vesta” the asteroid.

Shouldn’t it then be 21 rather than 22?

Ah!  There is the Russian edition of my “Corporate Portals” book — i.e., the purplish cover, 6th from left, next to the English edition. I get a kick from that book. Only book of mine that was translated, so far, and it is that book and into Cyrillic.

Yes, this is an affectation — though I like to think that is one of few, and the shelf is not in a prominent location. Yes, it is nice to glance at it every once in a while to see what my life has been — and these 25 books are very much my footsteps in wet cement. {SMILE}

P.S.: I just had, totally coincidentally, my latest Royalty Statement from ‘Elsevier‘, the publisher of my “Web Services” & “Corporate Portals” books. The e-Book versions of them are still selling. Wow. Not bad given that they were published over 13 years ago!

Near-Earth Asteroid 2012 TC4 Could Give Us Quite A Headache In 2017 — Near Miss?

Danny Fleming, a mathematician and astronomer gave me a heads up, via e-mail, on this. Thank YOU, Danny.

2012 TC4, as the ‘2012’ in its designation denotes, was discovered in October 2012 though it is POSSIBLE that it has been around for quite some time — though maybe not in its current, very near-Earth orbit.

FG14_01

Click to ENLARGE.

It is an ‘Apollo’ class asteroid (named after the prototype asteroid in this group). Apollos, in their relentless orbit around the Sun, crosses the Earth’s orbit — twice.

Well 2012 TC4 crossed the Earth’s orbit in October 12, 2012 coming quite close to Earth. At their closest they were 58,900 miles apart. That is 1/5 the average distance between the Earth and the Moon (what we call the ‘Lunar Distance‘ (LD)). The LD as such as 0.247 LD.

5 years later, again, coincidentally on the exact date, i.e., October 12, it will get within 0.034 LD of the Earth. That is nearly 7 times closer. Yes, it could get within 8,400 miles from us. That is close.

At that distance there is a very good chance that Earth’s (fairly strong) gravitational pull will capture it and pull it in. In which case WE will get SMACKED. Thought to be about 30 yards across it is NOT a huge asteroid, not large enough to annihilate all of us. But that is still plenty big enough to wreak quite a bit of destruction, especially if it lands near a city.

Not much we can do. It is not like the Earth can duck out of the way.


This orbital chart, using the JPL Small Body Database Browser,
shows that 2012 TC4 ends up right on top of us.
