TheSuperMarket User ID: 801546 United States 02/25/2013 11:42 PM Report Abusive Post Report Copyright Violation | Astro fk off, it won't hit. Quoting: Anonymous Coward 6818941 The latest Minor Planet Ephemeris data suggests that an impact is unlikely, with a nominal pass of 0.015 AU (2,277,700 Km from Mars's surface). You know what? No. It probably won't hit, but I wouldn't be honest if I didn't show this because there IS a possibility that it could hit. The latest JPL data has the nominal orbit with a close approach distance of 0.0007 AU and minimum distance still 0. That's interesting enough for me to make a thread about it and do my own analysis. Don't like it? You can fuck right off yourself. LOL! The way I heard you say "You can fuck right off..." in my head, was the same way this old lady said "Well you can just fuck right off!" to 2 mormons who knocked on her door in the movie Orgazmo (by the same guys who created South Park) LOL! |

We would just fuck up that planet too.

What else. a planet never gets knocked off orbit |
Dr. Astro (OP) Senior Forum Moderator User ID: 4211721 United States 02/26/2013 12:03 AM Report Abusive Post Report Copyright Violation | Doc, Quoting: Major Jim Any estimation as to the EMP that kind of.collision would generate? And any idea of the effects it would have here? Well it is thought that the SL-9 collision did generate an electromagnetic radiation outburst ( [link to link.springer.com] ) but the mechanism of such an event on mars would different due to the effective absence of a magnetic field. Nevertheless, if the gamma radiation generated during the explosion through bremsstrahlung and inverse compton processes at Jupiter as the above article suggests also applies to the martian atmosphere, then compton recoil electrons from the gamma rays hitting molecules in the martian atmosphere will indeed generate a current and some degree of EMP. It won't be knocking out power on earth though if that's what you mean. Last Edited by Astromut on 02/26/2013 12:04 AM |

I plugged those numbers into the Solar System Collision page ( [link to janus.astro.umd.edu] ) and came up with this: Energy Released: 19 billion MT (MegaTons of TNT) (Energy needed to Boil Earth's Oceans: 2000 billion MT) QUAKE!! Magnitude 12.5 (largest recorded Earthquake: 9.5) Crater Diameter: 659.0 km Crater Depth: 4.1 km Collisions this energetic occurred only early in the Solar System's history. Staggering, isn't it? Poor Martians. And this was just discovered last month and it might hit next year? Only 1 year warning. Just think if it was heading our way, there is nothing we could do about it. That's big enough to wipe out all life on Earth huh? It would put the rock that took out the dinosaurs to shame. And yeah, with only 1 year warning we'd be helpless to do anything about it. That's how it goes with long period comets. They never give much more warning than that, and if they happen to be headed your way... you're screwed at our level of tech. wasnt the rock that hit then 15 km large? I know it's energy was about 100 million megatons but i assume it's speed was much lower, about 17km/s..compared to this mars rock that is over 50kms all i know is i hope when it hits, that it hits the side we can see on mars. Will have my 8 in SCT out to record with my webcam |
hatch battener User ID: 35194960 United States 02/26/2013 05:24 AM Report Abusive Post Report Copyright Violation | Bumpity Bump Quoting: Anonymous Coward 34941837 Unfortunately for Mars, the calculations have been getting more and more favourable for impact since observation started. In early February the nominal close approach was 0.006 AU. [link to astroblogger.blogspot.ca] As of today, the nominal close approach according to NASA is 0.0007 AU. [link to ssd.jpl.nasa.gov] From Discovery News - this thing is legit. [link to news.discovery.com] This impact would rival those that occurred at the dawn of the solar system. Plug the calculations into [link to janus.astro.umd.edu] and the results are astounding: "Energy Released: 19 billion MT (MegaTons of TNT) (Energy needed to Boil Earth's Oceans: 2000 billion MT) QUAKE!! Magnitude 12.5 (largest recorded Earthquake: 9.5) Crater Diameter: 659.0 km Crater Depth: 4.1 km Collisions this energetic occurred only early in the Solar System's history." Even Leonid Elenin chimed in. [link to spaceobs.org] "Since C/2013 A1 is a hyperbolic comet and moves in a retrograde orbit, its velocity with respect to the planet will be very high, approximately 56 km/s. With the current estimate of the absolute magnitude of the nucleus M2 = 10.3, which might indicate the diameter of over 50 km, the energy of impact might reach the equivalent of staggering 2×10¹º megatonnes! This kind of event can leave a crater 500 km across and 2 km deep. Such an event would overshadow even the famous bombardment of Jupiter by the disintegrated comet Shoemaker–Levy 9 in July 1994, which by some estimates was originally 15 km in diameter." Just did some sleuthing, in respect to Emperor Kenton. The following link says that after Shoemaker-Levy 9 disintegrated "At least 21 major fragments were originally identified" and that "Reasonable assumptions about the spatial distribution of the grains and about the reflectivity of the nuclei imply sizes of 2 to 4 km (diameter) for each of the 11 brightest nuclei..." [link to archive.seds.org] So according to that report, the biggest fragment of the Shoemaker-Levy comet that hit Jupiter was 4 km in diameter. According to several reports, the comet that might hit Mars has a core of at least 50km. Or twelve times bigger than the biggest fragment that hit Jupiter. Another perspective, the distance between Boston and NYC is 300 km, so the comet that might his Mars has a diameter of about 1/6th the distance between Boston and NYC. The above link refers to a Mars impact that "would rival those that occurred at the dawn of the solar system." The planets including Earth have been mopping up those early solar system collisions for eons, with events that may have caused extinction level events on Earth. The eccentric orbit of Mars brings it closer to the Earth than any other planet at 35 million miles. The Asteroid belt which most all meteorites are believed to come from begins about 90 million miles from Earth and spans about 120 million miles wide. So Mars can be about 3 times closer to Earth than the closest part of the asteroid belt. An object with a diameter of 50,000 meters hitting the planet that comes closest to Earth, there seems little doubt that this will kick up debris in our direction. Bad news for Mars, but potentially worse news for humanity here on Earth. It takes us a year to swing around the Sun, so rough guess a year to a year and a half, we could be feeling the repercussions of this on Earth. And there's nothing anyone can do to stop it! |

Elenin There is a chance that the comet C/2013 A1 (Siding Spring), discovered in the beginning of 2013, might collide with Mars. At the moment, based on the observation arc of 74 days, the nominal close approach distance between the red planet and the comet might be as little as 0.00073 AU, that is approximately 109,200 km! Distance to Mars’ natural satellite Deimos will be smaller by 6000 km, making it 103,000 km. On the 19th October 2014, the comet might reach apparent magnitude of -8…-8.5, as seen from Mars! Perhaps it will be possible to accuire high-resolution images from the Mars Reconnaissance Orbiter (MRO). Since C/2013 A1 is a hyperbolic comet and moves in a retrograde orbit, its velocity with respect to the planet will be very high, approximately 56 km/s....

The only natural process capable of launching martian rocks to Earth is meteorite impact. Mars’ surface has numerous impact craters of various sizes and ages. To be ejected from Mars, a rock must reach the escape velocity of 5.4 km/sec, which is more than five times the muzzle velocity of a hunting rifle. An impact capable of ejecting the martian meteorites would have left a crater 10-100 km across. " ares.jsc.nasa.gov/ares/education/FactSheets/metsfrommars.pdf . |
