NASA Livestreamed ISON Conference (Fire vs. ISON)

Nope...NASA actually said so

Again, stop taking the osculating elements to be fixed and a true indication of the actual "orbital period!" Clearly I should have done a video on this yesterday. Oh well, I'll do one tonight.

Actually NASA didn't, the media took the idea on.

Q: What is the current est. size?
A: Upper limit of about 2km diameter. When comet passed Mars, camera was able to better estimate size at .6km-1.2km

Q: How do you know it's the first pass through solar system?
A: Mentions that it's a 1,000,000 period orbit. Never come through the solar system before and may never come again.


Am I wrong or is this totally contradictory to what they recently updated as far as a 500,000 year orbit?

ISONtards make ELENINtards look like Morgan Freeman narrating a video about space.

omg all anyone has ever done is complain that nasa wasnt talking about ison. now nasa is talking about ison and you complain that you dont want to hear it? It is just a comet. aside from the fact that it is currently moving through the solar system there really isnt that much to talk about aside from the way it interacts with the solar winds. there just isnt all that much to say about it.

Karl just said that it took MILLIONS of years for Ison to get to the sun from the oort cloud. He said that, using his stretched rubber band analogy, that the largest amount of acceleration occurs when the comet whips around the sun, and then the velocity is mostly stable as it returns to the OORT cloud, slows and then accelerates out of the oort cloud back on its journey toward the sun.

He then said you have to imagine its reaching the OORT cloud as like when you throw ball up into the air, and that as the ball reaches its furthest point it begins to slow, and then rapidly accelerates as it beings to fall again, but reaches its maximum velocity quickly and levels out until it reaches the sun again.

I would like to know exactly what object is in the OORt cloud which exerts a similar gravitational energy as the sun that attracts comets that return to the OORt cloud and slingshots them back out of the OORT cloud, towards the sun.

Nothing "slingshots it" back to the sun. In your screwed up view of orbital mechanics, what is "slingshotting" this Molniya satellite back to earth?

I have to say I am at least a little proud that I posted a thread that was pinned and consequently occupied by Astro and GG arguing with AC's and the like.

Makes me feel special.



Love you all.

Can anyone answer this question, if a huge ball of ice took a direct hit into the sun, would it cool off the sun? If I throw a snowball into my woodstove it would cool off the fire a bit right? Wouldn't the same apply the to sun on a much larger scale? Or, would this just be like one ice cube on a bonfire?

Would this slight cooling affect the earth at all? Would we feel any change? Thanks ;) The size of this iceball is roughly the size of Manhattan right? So, would it do anything to the sun?

throw a snowflake into a volcano and you might have a better analogy, lol. wont make a wit of difference
in fact, i dont recall of a single comet ever actually striking the sun. they all are vapourized in the corona.

Want a better example with explanation? I can give you one.
Its. Get yourself a HIV or other virus. We will see what gonna happen with your body, come on virus is so small so it can effect nothing in your body right? therefor people whos saying they are ill are only acting because virus cant do shit.

can't tell if that was sarcasm or a dig at us....
if not, well, glad someone is happy to see me now and then around this forum, lol.
