2015 TB145 discovered. Flyby Oct 31 at 15:14 UT. Dist: 1.26 LD. Size: 210-650 m.

No not the end of the world

But with only 37 observation and a uncertainty of 8
may keep a eye on this one.

Now to go find how close to the Moon it will get in theory it could get very close.
If the Moon is at the wrong place ya million to one.

Now look like we have 2 to 3 week to find out

Minor Planet Center

More detail

OK all you Doom Porn star what your verdict is this the one

It sounds like a Thundar. Get ready, Ariel and Ookla!

Our luck our moon will get a shave by this one causing lots of fragments to hit us.

Now that would be one of a kind Halloween night

Interesting coincident

Be on the lookout for Youtube videos, claiming this to be our next E.L.E. The doomporn junkies won't be able to resist.

Well I'll be a happy camper as soon as I find out where the moon will be

I know this prediction is far off by 5 years but it seems somebody already is in the know that the moon is about to get smacked by an asteroid...

Among other things predicted in that thread this was was the prediction of the moon: Prediction Thread

For 2020+ I can only give you two predictions, an asteroid will strike the moon and take a good chunk of it out. But rest assured this is by so called Divine Will and that asteroid was meant to hit Earth. Scientists will try to calculate how they got it wrong and I will give you the answer they forgot to carry over the factor that is the One of many One's

What are the chances the moons gravitation pull will attract it towards itself?

What gets me is that these things are being discovered (or we're only alerted) so close to the "fly by" dates. It seems lately that these asteroids are coming in our neighborhood at a rapid pace and someone's not keeping up.

Ha did not think off this scenario it has a period off 3.06 year
Maybe next time around it could get closer

a reply to: Trillium

Than I guess the prediction posted above here may be on the money than...2020 give or take we are looking at a good chunk of the moon hurling towards earth, I hope not..

OK, cant resist, if CERN is supposed to be a portal to the underworld and it is going to be opened to allow the hosts of hell on to earth, what more likely day than October 31? Halloween was supposed to be the day when the demons are let loose on the earth to run amok, it was then moved to Oct 31 so that the next day (Nov 1) all sains day, the saints drove them back to hell.

Revelation 9:1 Then the fifth angel blew his trumpet. I saw a star which had fallen down to the earth, and it was given the key to the abyss.
Rev 9:2 The star opened the abyss, and smoke poured out of it, like the smoke from a large furnace; the sunlight and the air were darkened by the smoke from the abyss.
Rev 9:3 Locusts came down out of the smoke upon the earth, and they were given the same kind of power that scorpions have.

Ok using Celestia program and the Minor Planet Center graphic
I come up with this



Now going back to Celestia and see if I can layout the proper orbit
for 2015 TB145 onto the background

It been over a year since I created one of those files

Right now my asteroid show up a few AU away from our sun LOL

So look like the moon is close to 2015 TB145
moon is below the red line on left side

Does this take in to account the gravitational pull of the Earth or moon?

Wow, this looks like it's pretty close.

I am worried as well Cinrad about not only gravity, but also it seems as they are not entirely sure of it's path and has a condition code from nasa of 9 (highly uncertain) (condition code description)

TB 145 Nov 2 2015

The orbital uncertainty will not seriously affect the prediction for the close approach of November 2. It's the position of the asteroid in the future that is poorly known. More observations will improve the accuracy. As for the question regarding whether the Moon's gravity will pull the asteroid in towards it, this is already accounted for in calculations of this kind.

It does. All such orbital calculations from MPC and JPL include major gravitational influences, such as from planets, moons, and even the bigger of the asteroids. However, with only so little observing time, the orbit might get influenced by a noticeable degree by smaller gravitational influences.

LOL I thought the same thing!

From Wiki Leak
October 2015 the asteroid will pass about 0.0019 AU (280,000 km; 180,000 mi) from the Moon and then pass about 0.0032 AU (480,000 km; 300,000 mi) from Earth

WikiPedia

So look like it a safe distance so faw

From itelescope.net

Always use the latest possible orbital elements and ephemeris. Note that at the moment the JPL and MPEC ephemeris do not converge between the 29th and 1st Nov, reflecting how current orbital uncertainties feed into their orbit models, you you will need to keep checking until they substantially converge.

JPL ephemeris for astronomical twilight 31st 06 10 13.22 +32 21 01.1
MPEC ephemeris for astronomical twilight 31st 05 44 46.8 +26 28 06

Now a pretty big difference ???? why
