This is scary. This means that unless we catch a celestial object coming towards Earth farther than a year out we probably won't know if it will impact us.


That's exactly what I pick up on this too. A comet may hit next year? and they didn't know about it until now?

The problem with comets is, unlike asteroids which orbit mostly between Mars & Jupiter, they mostly orbit in what is known as the Oort cloud which is almost 1 light year away from the sun. Along with being a hell of a long distance from us they are actually quite dark due to being coated in dust that is almost like powdered charcoal.

Only once a comet enters into the inner solar system can we really have a good chance to spot them. Sadly though, this means if it's an unknown comet, we won't have much of a heads up if it is coming straight at us.

This, now I'm reading about this Oort Cloud.

Kinda neat.

In all seriousness, if this happens, with NASA having that much hardware in the area able to observe it up close, NASA will be having the ultimate Geek FAP.

It really is a big deal scientifically.

re: Very Large comet may hit Mars in Oct 2014


interesting illustrations you have here. In he second picture I see they show a "brown dwarf" just outside the orbit of Pluto and the Kuiper Belt. I'm guessing this is the hypothesized "Nemesis" star that some astronomers have wondered about for years. Their thinking is our sun has a very small companion (most stars in the universe are binary systems)star. They think this small brown dwarf star is on an very long elliptical orbit and every 160 million (I think that's the number if I remember right) it's orbit disturbs the Oort cloud and sends literally millions, maybe billions of comets in every direction, including inward towards the inner solar system.

This "Nemesis" star has never been found or even proven to exist. The problem with it is similar to the one of finding comets in the Oort Cloud, it's very far away, it's small and it gives off little if any light.

(A Brown Dwarf is really a failed star. They are larger than Jupiter but much much smaller than then sun. They are really big balls of gas that never had enough material to reach the point where a sustain nuclear reaction would ignite into a full blown star. This is why they are so hard to see.)

As for the idea of the Sun having a companion star, it is possible but unlikely. Most binary star systems see two stars that orbit one another in a rather tight orbit. As far as I know we have never observed a binary star system where the stars' are as spread out as what the Nemesis theory calls for.

How do people come up with this shit? Is it like conspiracy theorist that take any shread of evidence and run with the most outragious explination?

The basis of the theory is what appears to be a rather even pattern found in the fossil records of mass extinctions every 160 million years. It's not really all that much of a crack pot conspiracy thing as much as is it a few scientists thinking outside the box. They are looking for evidence of the "Nemesis" to test the theory but so far have not found anything. The main problem is that despite the advances in telescopes, both terrestrial and orbital, it's still almost impossible to see anything that small and that faint at such an extreme distance.

I personally think it's highly unlikely there is a brown dwarf on some very long elliptical orbit that intersects the Oort cloud every 160 million years but will admit it's not entirely impossible either.

Something as large as a brown dwarf that doesn't perturb the orbits of the outer planets?

I don't buy it. They'd need some very good evidence.

Yeah, I think it's highly unlikely there is a brown dwarf out there. However, the distance they are talking about with this hypothetical brown dwarf would be so far out it would not really affect any of the planets. Remember, according to their theory it only interacts with the Oort cloud for a small window of time every 160 million years. Now considering the Oort Cloud is about 1 light year from the sun and a brown dwarf is not much bigger than Jupiter, it would not really have any gravitational interactions with anything in the inner solar system, even at it's theoretical closest point.
