    I’d like to point out that a whole planet has hit our own planet in the past and this impact created the moon. Might not technically count as a meteor, but I still think it deserved to be at the top. Or al least mentioned.

      List say meteor. You say planet. Planet no be meteor. Meteor wins!

    Good timing TopTenz, I just read about a meteor striking the moon on cnn about 5 minutes ago. Nice synergy.

    But how can these be true? We all know the universe is only thousands of years old :)

    Ugh… – no, these are not the 10 biggest meteor strikes in history. Let’s do the list….

    10. To start with, Barringer Crater is actually pretty tiny, less than 1 mile wide. It’s well-preserved, but it’s actually very small. There’s a good 130 or so confirmed craters that are larger than Barringer.

    9. Bosumtwi – again, a very nice exposed crater. Also not one of the largest. 65 craters bigger than this.

    8. Mistastin – again, nice, exposed crater. 32 craters bigger.

    7. Gosses Bluff – nice, except that 37 craters are bigger. That means It’s smaller than Mistastin.

    6. I really like Clearwater craters… one’s (East) smaller than Mastistin, but the other (West) is bigger. Still not even in the top 20 yet.

    5. Tunguska – Oh, dear Lord. OK, first and foremost, Tunguska likely was some sort of meteor. Given the remote location and lack of observers, the concept of a relatively unseen meteor hitting the earth’s atmosphere and doing a nice, big airblast is very possible. But there’s your second problem: it was an airblast, not an impact. It didn’t hit the ground and therefore, there is no real crater to speak of… just a widespread area of top-level destruction. This, most certainly, does not belong on the list, and most certainly not at #5.

    4. Manicougan – again, very nice. And we’re finally in the top 10. Actually, we’re at #4. Congrats – it’s the first one that’s correct on this list.

    3. Sudbury – and we finally enter the top 2. Sudbury is currently the 2nd largest crater known on the planet. Wait a minute…

    2. Chixiclub – the famous dinosaur killer. It’s also, believe it or not, about the same size as Manicougan. I know, right? So shouldn’t this be #3? Yeah. It should be.

    1. Vredfordt – the largest currently known impact structure on Earth. Good job. Except that recent measurements have shown that there may be another impact structure that should be #1… Sudbury. It’s believed that it was actually the largest impact, but weathering done by Canada’s… weather… and more active tectonics had worn the crater away.

    So, I know what you’re saying. 5minutes… don’t you do lists on Presidents and guns? How do you know so much about craters? Answer: lots of lonely nights at the library during my high school years. The other question: what’s the real top 10? Well…. (and keeping in mind that Wikipedia is NOT the best source of crater diameters on the planet, which is why I use the Earth Impact Database)…

    1. Vredfordt – still the largest today – 200 km
    2. Sudbury – 180 km
    3. Chixaclub – 150 km
    4. Manicougan – 100 km
    5. Popigai – nice, big 100 km crater over in Siberia
    6. (tie) Acraman – heavily eroded crater in Australia – about 85 km, which ties it with…
    6. (tie) Chesapeake Bay – another 85 km crater – submerged, this time – that helped form the coast of Virginia
    8. Puchezh-Katunki – an 80 km crater over in the Nizhny Novgorod Oblast in Russia
    9. Sijan – Sweden gets an entry with an 80 km crater
    10. Morokweng – South Africa’s other entry is a 70 km crater, which, with Vredfordt, is really just proof that God doesn’t like South Africa.

    You’re welcome.

      THIS LIST IS ALSO SERIOUSLY WAY OUT (OFF) WITH THE ENERGY RELEASED from these impacts.. for instance, the Chixculub impact was estimated to be 100 MILLION MEGATONS
      (The equivalent of 5 MILLION, YES, *MILLION* MODERN-DAY WARHEADS (eg, based on the average 20 – 25 megaton warhead of the USA)
      This list states it is ’1 billion kilotons’ (1 million megatons).. so it was actually 100 (a hundred) times more powerful than this list states. This meteor was 5 miles in diameter, so why does it state that the Gosses Bluff meteor (15 miles diameter x 40,000 MPH) created a force of ‘just’ 22,000 megatons (1,000 nuclear warheads)
      The biggest crater I have heard of is actually one in Antarctica which hit 251 million y/ago, it was approx. 20-25 miles diameter and exploded with the force of 1 *BILLION* nuclear warheads (approx. 20 BILLION MEGATONS – Yes, you heard correctly- see URL http://www.youtube.com/watch?v=M0DcuXVpDHY

    If proven it would dwarf any of these.
