Good work. Not sure if you have mentioned this before but if this Comet hits Mars, and creates fragments leaving its orbit, would these Mars fragments (meteors), potentially impact Earth? How long would it possibly take if a large couple of fragments break off of Mars, and head to Earth? Is this possible? Thanks [/quote] Think of how difficult it is for humans to send objects to Mars. You can't just throw something out there and expect it to head straight to the nearest planet. At their nearest point, Mars and Earth are 54.6 million kilometres apart. At their farthest point, 401 million kilometres. The two planets sit in two completely different orbits moving at different speeds. Anything headed toward Earth's orbit would be ultimately headed to the Sun, rather than a bee-line for Earth, and faces as much chance of meeting up with Earth as it crosses our orbit as any other asteroid or comet out there. And, that's IF anything large gets flung out with enough velocity that it's actually able to escape Mars' gravitational pull (again, think about how difficult it is for humans to actually get stuff off our planet). Sure, evidence tells us that pieces of Mars have made it here in the past, and some pieces from a Martian-Asteroid impact would probably make it here over time, but the odds are that it would take a VERY long time. Space is very big. [/quote] well, escape velocity from Earth is only 25,000 mile per hour, and Comet Siding Spring will be traveling at 120,000 miles per hour: so, you can imagine that a whole lot of Mars surface will be traveling in the opposite direction (ejecta moving at more than the escape velocity for Mars) from the incoming mass smashing into the surface. [/quote] You're doing an awful lot of "imagining" in your "theories". How about a little math? Also, since the asteroid will be travelling from the outer solar system, and since you believe that ejecta will be launched in the opposite direction of the asteroids direction, isn't it most likely that the ejecta will be headed back to the outer solar system, under your "theory"? [/quote] well, the rules for our ejecta, as the Comet is striking the surface of Mars are governed by Newtons Third Law of Motion (action and equal and opposite reaction). and, according to Newton's First Law of Motion: a body in motion will stay in that motion until or unless it is acted upon by another body. so, in terms of our "ejecta", yes, once the ejecta breaks free of Mars gravity it will keep going in the same direction with the very same constant velocity (until it is hit by some asteroid or it travels close to the gravity of a mass planet) [/quote]
Original Message
The core of the comet will be moving 56 kilometers per sec when it smashes into Mars. The explosion it creates will be equal to
40 BILLION 500kt nuclear bombs
(avg US and Russ arsenal weapon) going off at once, or 20 billion megatons of TNT, or 1.33 trillion Hiroshima bombs, or 1.3 billion Castle Bravo explosions. Its enough to kill all life on the planet if any were living there.
Astronomers predict a large-scale disaster on the Red Planet in October 2014, when a comet may ram into Mars, creating a 500-kilometer crater, the website of the Russian observatory ISON-NM said.

comet core 30 miles across
collision speed 35 miles per second (126,000 miles per hour)
It may make Mars temporarily as bright as the sun. The crater left behind will be 500 kilometers across. A lot of rock will be ejected into space and become stray asteroids. This will be an epic event.
