The lightweight spaceship (commonly abbreviated to LWSS) or (rarely) small fish[1] is the smallest orthogonal spaceship, and the second most common spaceship after the glider. It moves at speed c/2 and has period 4. It was found by John Conway in 1970.

Commonness

Random soups investigated by Achim Flammenkamp emitted one LWSS for approximately every 615 gliders.[2] The LWSS is also the eighteenth most common object on Adam P. Goucher's Catagolue.[3]

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 indefinitely by attaching it to the back of itself. Interestingly, a hivenudger with symmetric rear (that is, both rear spaceships being of same "weight") can pull this tagalong.
