We know that the Chicxulub impactor had a size of about 10 kilometers but no large pieces were recovered. Large recovered meteorites: Namibia - Hoba Grootfontein ( 60 Tons ) Greenland - Cape York: Ahnighito ( 31 Tons ) Mexico - Bacumerito ( 27 Tons ) China - Xinjiang Uygur ( 25 Tons ) Tanzania - Mbosi Tanganyika ( 16 Tons ) Australia - Mundrabilla ( 11.5 Tons ) Post Extras:       Astrojensen Post Laureate Reged: 10/05/08 Loc: Bornholm, Denmark Re: Largest recovered Meteorites [Re: PhilCo126]       #5680731 - 02/15/13 06:29 AM Edit   Reply   Quote Quick Reply   The Moon? 7.3477x10^22 kilograms. It did hit earth once... And we've been walking on it and giving it a good kick, so... Clear skies!

However, this Giant impact hypothesis does not explain the similar composition of Earth and the Moon.

"The 34-ton Cape York (nicknamed Ahnighito) iron meteorite."

However, the total mass of the Campo del Cielo fragments found so far exceeds 60 tonnes, making it the heaviest meteorite ever recovered on Earth.[5]" Cut and paste from Wikipedia Post Extras:       Pages: 1 Previous   Index   Next   Threaded   Extra information 0 registered and 0 anonymous users are browsing this forum.
