is a small systrem, and there is a small central rise at the mid-point of the floor. This crater is believed to have formed about 2.8 billion years ago.
In 2002, a meteorite was discovered in the
Oman desert by Edwin Gnos of the
University Of Berne . This rock, identified as ''Sayh al Uhakmir 169'', is believed to have originated from the Moon. It was ejected from the surface during an impact that occurred less than 340,000 years in the past. Scientists now think that the rock originated from the crater ejecta blanket surrounding Lalande.
By convention these features are identified on lunar maps by placing the letter on the side of the crater mid-point that is closest to Lalande crater.
