The distance of Tau Ceti is set at twelve light years. The departure is from the Cape Canaveral base in Florida. We set: a=1.052ly/y² D=12al We want to know when and at what speed the spaceship will cross the Tau Ceti system in the Earth's frame of reference. We want to know at what speed Tau Ceti will cross the rocket, and at what time in the rocket's frame of reference. <http://nemoweb.net/jntp?cUdAZOAXeDiq9itiz1KAp6xlORU@jntp/Data.Media:1> R.H. -- Ce message a été posté avec Nemo : <https://www.nemoweb.net/?DataID=cUdAZOAXeDiq9itiz1KAp6xlORU@jntp>
