The lightweight spaceship (or LWSS for short or small fish[1]) is the smallest orthogonally moving spaceship, and the second most common spaceship (after the glider). It moves orthogonally at c/2 and has period 4. It was found by John Conway in 1970.
Tagalong
In April 1992, David Bell found a tagalong for two lightweight spaceships (or two middleweight spaceships or two heavyweight spaceships). It can be extended infinitely by attaching it to the back of itself.
