88611 Teharonhiawako
binary trans-Neptunian object
88611 Teharonhiawako (provisional designation 2001 QT297) is a trans-Neptunian object and a member of the cold classical Kuiper belt. Teharonhiawako was discovered on 20 August 2001, by the Deep Ecliptic Survey, and its companion, 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.
The pair form a binary minor planet, which orbit each other. Their orbit has the following parameters: semi-major axis—27670±120 km, period—828.76±0.22 days, eccentricity—0.2494±0.0021 and inclination—144.42±0.35° (retrograde). The total system mass is about 2.4×1018 kg.
The primary measures about 220 km in diameter. The large companion is named Sawiskera (formally designated (88611) Teharonhiawako I), 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.

Why this record matters
“88611 Teharonhiawako” is worth following because a concise public description often conceals a longer documentary argument. Here, Teharonhiawako, binary and trans-Neptunian provides the most credible route into that argument.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 6, 2026. The linked authority identifier is Q157625. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2001, 2007 and 1018.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
