List, For those that are interested in transit times and lunar impacts that result in Lunar Meteorites here on Earth, Dr. Randy Korotev has written a very good summary on this topic and his website answers the basic questions posed- http://meteorites.wustl.edu/lunar/
Some of the questions answered are- How Did Lunar Meteorites Get Here? Do All Lunar Meteorites Come from One Big Impact on the Moon? Does It Take a Big Impact to Launch a Lunar Meteoroid? and many more. Take a read of his website written for the Washington University in St. Louis. Thank you Dr. Korotev! Dirk Ross...Tokyo P.S. The reason I posed the question in the first place was because of the recent announcement about a large lunar impact recorded on the Moon- http://lunarmeteoritehunters.blogspot.jp/2014/02/biggest-observed-meteorite-impact-hits.html It would be so cool if something was launched from this impact and it makes it here to the Earth in the coming years! ----- Forwarded Message ----- From: drtanuki <[email protected]> To: Ted Bunch <[email protected]>; meteorite-list <[email protected]> Cc: Sent: Monday, March 3, 2014 3:47 AM Subject: Re: [meteorite-list] Lunar Meteorite Quiz - How big an object with velocity to get a new Lunar Meteorite to Earth? Dear Dr. Bunch, Thank you for refining the question and clarification. Sorry I overlooked your address on the "to address list". Have a safe trip.

I have to go on a trip in a few minutes, but an additional consideration to mass, ejection V & angle, etc. is the consideration of orbital mechanics of an ejected mass as to whether it is reaches a stable orbit, one that ultimately decays into earth or one that may escape the gravitational effects of the Earth-moon system.
