Validation of 2005 YU55's Trajectory Through the Earth-Moon System on 11/8

[link to apod.nasa.gov]

Before you get snippy about the quality of the image, keep in mind that the asteroid is only 400 meters across and only got marginally closer than the Moon.

That's what they WANT you to think.

Good Work Astronut, notice how Hogland et al have gone all quite?

Quiet in a kinda Harold in A Hotel way?

Believe nothign until it actually happens, THEN panic.

What's the BS flag for? You must be a doomtard who is crying in a closet!

Thanks Astronut! You ROCK!!!

That was the first time I have ever seen an asteroid live thank you for that, was a good watch!

Would gladly watch anything you do live again :)

Good Job and thanks many people listen to Hoagland on C to C and take it serious nice to know who was right on

Good work Astro.
I heard a few rumours about the potential for YU55 to keyhole on this flyby, & I know it's still early days but has anyone calculated if it continues to follow predicted trajectory or has it altered course? Each significant gravitational interaction is going to skew the numbers slightly by multiplication of error right? So JPL showing predicted orbits way into the future is going to be guesswork at best, surely?
I wonder how many orbits before it hits?

I started watching about 20 minutes into the YU55 show, Astromut, and kept it full-screen until the picture of Jupiter (which, I was there for that show, too. ) It is because of you that I continue to return to this forum. Thanks so much for your knowledge and expertise.

Wow, thanks for the super-pin man!

Here's a whole bunch of images from a variety of sources, including the infrared images from the Keck AO.

Faker !

Bloody well right.

Nice job Astromut, you're a good bloke. Nice to see there's someone who loves astronomy even more than I do lol!

The concern isn't the earth flyby, astronomers are more interested in what the orbit looks like after a Venusian flyby later on. This asteroid has close approaches to both Mars and Venus as well. They've ruled out impacts for this century, they want to know its orbit well enough to rule out impacts in future centuries. With all the amateur data pouring in they may be able to do just that.

Ah, the sounds of desperate doomtards lol. No, it's not fake. Not only is it real, I even streamed it in realtime for GLP.

I love how everyone is all on about NASA/JPL and that, but don't seem to realise that with a lot of these objects, it is amateur astronomers that contribute a lot of research ...

Wow, thank you! I'm so glad I was able to provide my view of the asteroid for everyone. There was a ton of interest from what I could tell, but few options (other than actually owning a sizeable scope) for viewing it the way you would see it if you looked at it in an eyepiece or by eye (had it been possible to see by eye).

Indeed, and there's absolutely nothing stopping anyone from running an orbital determination for themselves using the same data. Everyone with a modern computer has the computing power to do it.

Nice work, Astromut. I always enjoy your posts/threads.

was this yu55 the elenin asteroid or something different?

A different object. Elenin was a long period comet. YU55 is an asteroid with a near-Earth orbit.

I think (not 100% sure) Elenin disintegrated though.

I may not agree with everything ya say but I gotta point out that, I was thinking again today after hearing a level headed person on the radio how I use to not like down to earth people irritated me to come out of the clouds. On the other hand I use to be a pretty hardcore skeptic and can remember those times.

I can appreciate someone who just uses pure "common sense", I have a friend whose like that and seems a fitting yin and yang we both have the pendulum of the extremes and toss things back and forth probably somewhere in there is the middle.

bahahah the music - win

nice video astro

You know brings up another good point seems merely money is standing in the way and I guess some sort of book to get me started on astronomy.

When I was about 8-10 years old we went to the history museum in Austin and they had a miniature planetarium there. They covered the stars and went over that Betelgeuse is a red giant star and I kept getting this weird feeling like I was from there. A planet in the constellation of Sagittarius wasn't till later that I found out about astrology and that my star is the center star in the belt of Orion. Always felt as a little kid that I was from another world because this one was so foreign to just my basic understandings of life.

The stars fascinate me.

Shut the fuck up.

Great post as always. Astromut has been the scientific voice of reason around here for quite some time!

Can we please find some moon bases with that telescope? All this logic and rational thought is so passé.
