Nice GIF of the fast gyrating http://www.skyandtelescope.com/community/s...g/30686199.html
QUOTE ...telescopic observations show that 2008 TC3 was gyrating wildly before it hit. According to Czech asteroid specialist Petr Pravec, it was "definitely a tumbler." His analysis reveals two distinct periods of 49 and 98 seconds long. One is probably due to rotation and the other to spin-axis precession, but he can't tell yet which is which. But he notes that this ranks (or ranked!) as one of the three fastest-spinning asteroids known. Another one here http://news.astronomie.info/ai.php/headlines/200810020 -------------------- |
