88611 Teharonhiawako (provisional designation ) is a trans-Neptunian object and a member of the cold classical Kuiper belt, measuring about 220 km in diameter. It is a binary object, 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. The two components together are known as the Teharonhiawako - Sawiskera binary system.

Discovery

Teharonhiawako was discovered on August 20, 2001, by the Deep Ecliptic Survey, and Sawiskera was identified a month later.

Naming

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.

Binary

Teharonhiawako and Sawiskera is a binary minor planet which orbit each other. Their orbit has the following parameters: semi-major-axis—, period—, eccentricity— and inclination—(retrograde). The total system mass is about 2.4 kg.
