On the other hand, a con-sistent conclusion is drawn from the impact jetting sce-nario that when the impact velocity exceeds 2.5kms−1, about 1 % of the impactor’s mass becomes the progeni-tor of chondrules for both protoplanet-planetesimal and Witryna11 lis 2015 · Chondrules are one of the most primitive elements that can serve as a fundamental clue as to the origin of our Solar system. We investigate a formation scenario of chondrules that involves planetesimal collisions and the resultant impact jetting.

WitrynaWhat Are Chondrules and Chondrites? Chondrules are rounded objects typically from 0.1 to 5 mm in diameter, with an average size of roughly 0.4mm. They are made primarily of olivine and pyroxene with the occasional bits of glass and other trace minerals.
