The home star of the E.Ts who are here, they call Toxalonta.
We call it Pi3 Orionis.
It is 23,6 LY away. It took only 8 of their lifetimes to get from there to here. Not direct.
Directly, 23.6 LY would take 236000 years at 108,000 kmh. 1 of their lifetimes is over 50,000 of our years.
66,000 mph is not fast enough to suffer micro particle damage, and slow enough to manouver around large objects.
