Toutatis

Close approaches and collision risk Toutatis makes frequent close approaches to Earth, with a currently minimum possible distance (Earth MOID ) of just 0.006 AU (2.3 times as far as the Moon ).

Giant basin The giant basin at the big end of Toutatis has a diameter of ~805 m, suggesting that one or more impactors may have collided with it there.

In 2006 Toutatis came closer than 2 AU to Jupiter.

Its rotation combines two separate periodic motions into a non-periodic result; to someone on the surface of Toutatis, the Sun would seem to rise and set in apparently random locations and at random times at the asteroid's horizon.

Radar imagery shows that Toutatis is a highly irregular body consisting of two distinct "lobes", with maximum widths of about 4.6 km and 2.4 km respectively.

The gravitational perturbations caused by frequent close approaches to the terrestrial planets lead to chaotic behavior in the orbit of Toutatis, making precise long-term predictions of its location progressively inaccurate over time.

Toutatis is not a monolith, but most likely a coalescence of shattered fragments.

Toutatis will approach Earth again in 2016, but will not make another notably close approach until 2069.

With an uncertainty parameter of 0, the orbit of Toutatis is very well determined for the next few hundred years.
