Meteor vs. Crater and Ray Size
How do you chart meteor speed versus impact
crater diameter? and meteor speed vs ray length?
The best way to chart the velocity of a meteor is first to identify
which shower it came from. The list of meteor streams can tell you,
in many cases, what the velocity was. For example, any Geminid would
be coming in at about 35 kilometers per second. A Leonid would be
twice that velocity.
