, with a large companion named Sawiskera (formally designated (88611) Teharonhiawako I Sawiskera), which at 126 km in diameter is about two-thirds the size of its primary.
Teharonhiawako was discovered on August 20, 2001, by the
Deep Ecliptic Survey, and Sawiskera was identified a month later. The primary is named after
Teharonhia꞉wako, a god of
maize in the
Iroquois creation myth, while the secondary is named after his evil twin brother
Sawiskera. The objects were named in 2007.
Sawiskera's orbit has the following parameters: semi-major-axis—, period—, eccentricity— and inclination—(retrograde). The total system mass is about 2.4 kg.
