The likelihood of collision in the distant future is considered to be very small. [27] As a planet-crossing asteroid, Toutatis is likely to be ejected from the inner Solar System within a few million years. In 2004 a chain e-mail falsely claimed that Toutatis had a 63% chance of impacting Earth then. In fact, Toutatis passed by at 1.5 million ...
The asteroid Toutatis is listed as a potentially hazardous near-Earth asteroid, yet poses no immediate threat to Earth.(Radar image taken by GDSCC in 1996.)A potentially hazardous object (PHO) is a near-Earth object – either an asteroid or a comet – with an orbit that can make close approaches to the Earth and which is large enough to cause significant regional damage in the event of ...
4179 Toutatis: 2.45: 1934 Chang'e 2: 2012 3.2 0.70 Flyby; [1] closest asteroid flyby, first asteroid visited by a Chinese probe. 1 Ceres: 939.4 1801 Dawn: 2015–2018: 35 0.07 First "close up" picture of Ceres taken in December 2014; probe entered orbit in March 2015; first dwarf planet visited by a spacecraft, largest asteroid visited by a ...
The orbital period distinction is of importance in the evaluation of the risk from near-Earth comets because short-period NECs are likely to have been observed during multiple apparitions and thus their orbits can be determined with some precision, while long-period NECs can be assumed to have been seen for the first and last time when they ...
In September 2004, the well known PHA 4179 Toutatis came about 4 Lunar Distances from Earth. Due to its diameter being over ten times larger (5.7 km) and its closer approach, Toutatis at its closest (mag 8.9) was about half an apparent magnitude brighter than 1998 WT 24 was at its closest (mag 9.5).

101955 Bennu (provisional designation 1999 RQ 36) is a carbonaceous asteroid in the Apollo group discovered by the LINEAR Project on 11 September 1999. It is a potentially hazardous object that is listed on the Sentry Risk Table and has the third highest cumulative rating on the Palermo Technical Impact Hazard Scale. [9]
433 Eros is a stony asteroid of the Amor group, and the first discovered, and second-largest near-Earth object.It has an elongated shape and a volume-equivalent diameter of approximately 16.8 kilometers (10.4 miles).
69230 Hermes is a sub-kilometer sized asteroid and binary system on an eccentric orbit, [10] classified as a potentially hazardous asteroid and near-Earth object of the Apollo group, that passed Earth at approximately twice the distance of the Moon on 30 October 1937.
