Asteroids

We were talking about big space rocks in another thread, so I was checking the details of this last close approach.

And, you know, the Earth will change the orbit of the asteroid. This time it knocked significant days off the solar orbit. And it's coming back in 2023, maybe as close as 20K kilometers, but, really more likely outside the lunar orbit.

It's already changed it's classification in earth-passing orbits, down graded to just one pass thru our orbit instead of twice per it's orbit.

This next time may well, knock it rounder and totally inside the orbit and not Earth passing, any more. Pretty cool, huh?

Until we remember that Jupiter is quite capable of aiming these things at us and we may not even get one orbit before impact. And Earth has the in-alienable Right to be in the way.

Just bringing a picture, to show. I didn't know about the L point asteroids in Big J's orbit. The stuff following and leading by 60 degrees. And all of Jupiter's satellite mix is perturbing to all that Greek and Trojan rock. This is the true butterfly sneeze of chaos, to me.

Anything, including our own research Satellites in Solar orbit, sling-shotting around, could have already spelled WipeOut, among the BIG rocks.

But, it doesn't matter, our ticket punch is out there somewhere. We need to get out and hide some DNA samples around the System. Colonies.

Jupiter has been known to eat/sweep up so to speak comets,and asteroids from it's gravity.If Jupiter (if I remember correctly) ate a couple dozen Earths would increase in mass in turn increasing it's own gravity.It would start a nuclear chain reaction in it's core with the hydrogen,and turn into a star,or Sol II.

Jupiter not only has been a potential protector of Earth but could be our future Sun when ours fizzle in 4 billion years,but then again the fizzle will sizzle,and change orbits of the planets I am sure.

I watched NOVA last Saturday, it was about the meteorite over cheblinsk in feb. the program was saying how the very shallow angle of entry spared the city. if it had come in at steeper angle the shockwave would have been more powerful, increasing as angle increased. the city dodged a bullet, if they had been destroyed I think we would be talking about a little more than silly marriage customs and killing tools this morning, and instead talking about human survival. I regretfully say that since the city wasn't destroyed, we are gonna keep our heads in the sand and pretend/not think about the rock out there with our name on it, and we wont be ready or have a hope when it comes.

The universe is a violent place to live. All we need to do is look up at the moon to get a quick idea of what our chances are concerning a strike on this planet. That's what Earth would look like if we didn't have an atmosphere and enviornment erasing the evidence of previous strikes. I think human life spans are so short in comparison to the age of our planet and the Universe, that it's hard to really appreciate just how common these kind of things are to our planet.

This planet didn't just appear, it's the process of many astroids, comets and space dust being pulled together by our old pal gravity. The Earth is always growing through this process. Luckly, it's mostly from space dust and small rocks that don't add up to too much trouble for us as a planet. On the other hand, once in a while the Universe pulls the pin and rolls a granade through our collective door, metaphoriclly speaking. It's a fact that right now, this very minuet, a planet killer has us in it's crosshairs and is bearing down upon us. Where from and when are the only uncertainties in that equasion. The only hope we have is that it won't get here while we are alive and walking this planet. One thing that is for certain is that sooner or later some poor bastards will get their ticket punched, assuming we don't die off first from the thousands of other things that take turns killing off species on this planet.

I'll say this for a strike during my lifetime, if it does have to happen while I'm alive, I hope that fucker hits me right on top of my head when it comes in. I wouldn't want to be here for the afermath that the folks that might survive the initial impact are going to face. Truly hell on Earth.

Except the Sun won't fizzle out. Our star will burn yellow in the main sequence and won't have enough energy to nova.

When the core fuel runs out, it won't blow up or fizzle. It will expand Red into the orbit of Earth and consume it. This will possible be enough energy to ignite Jupiter, but we need a better seat for that.

I can dig and respect your opinion on this one, my man. Fuck 'em... never say die.

If the shit does hit the fan, the fate of our collective genome rests firmly in your hands then, I'll be outta here if I can help it.

You are right,but a dead star is in the future long aways.

I do not know your tastes,and you may find the older ones boring.

There was a long hiatus then they made a crappy movie.

Then the BBC started doing episodes again........ http://en.wikipedia.org/wiki/Doctor_Who_(series_1)

My suggestion is the newest incarnation starting with ^ Christopher Eccleston,and it gets better,and better with David Tennant,and currently Matt Smith.

I would do that ^,and as for my older favs is Tom Baker,and Sylvester McCoy.

Unfortunately the older B&W episodes some of them got destroyed by a short sighted BBC archivest.


Anyway that is what I recommend is just start with the latest incarnation with Christopher,and there is no real need to know the previous older episodes.


Something aimed at a younger audience is the Sarah Jane adventures where unfortanately the actress Liz Sladen died of cancer,but

She was in the Dr who series in the 70's-80's,and she was a good actress with a lovable character.

Good luck.

T.A.R.D.I.S. time and relative dimensions in space the time machine with a broken chameleon circuit so why the police box.

Dr Who is the last of the time lords where his race got wiped out in a time war.

The doctor cannot die but regenerates into a new body.

The doctor allways takes up compannions (humans) to go on his adventures.

2 of his biggest nemesis is the Master,and me the Daleks,but he has many more.The Daleks are the hyper evolved Kaled race of planet Skaro,and was created by a mad scientist named Davros.

That's some tidbits besides the Doctors famous sonic screw driver lolzzz

Torchwood is a spinoff I have not seen much of to form an opinion.

Have fun.........

Why do people who dont follow science reply here, honestly.... I'm sorry, but WTF.

First off;
OP: Do you realize that there has been an inner and outer asteroid belt for millions of years? Let alone the fact that Jupiter has a >>> mass than Earth, therefore having a much larger gravitational effect on the objects than Earth... I really hate talking cosmos with kids, so I will not proceed any further unless a legitimate argument ensue.

Have fun

One thing I don't understand is why don't we advance enough or what ever so that we can harvest asteroids and bring things back to earth and we can use it to do research on also.
