I ain't gonna make any big deal about this 2.4 km asteroid having a couple of Torino Scale 1's on its risk table. But, here is my question, there are more than 20 passes inside the Moons orbit, I am guessing from the sigma impact distances and 'width' that would still hold , with further computations. Should make for some interesting radar observations. Optical too. Maybe a manned expedition! Kind of wish JPL would do an non-two body , geocentric animation of this one. |

This might be a really kooky idea, but it passes at only 14 km/sec or so, so the delta V is only about twice what it takes to get into orbit .... how about putting a transponder on the thing? =) A nice corner mirror for a laser would be fun too, but it's probably spinning ... If it had a transponder, you could get accurate positions over quite a substantial time period, and really nail the orbit down ... perhaps even gather data about forces on the object (measure drift due to solar pressure, etc). Feasible or loony? =) |

Could you put a dozen or so of them on some kind of mesh that would wrap around the thing? Then when it spins you still see at least one. Would multiple transmitters, maybe at difference frequencies, so you could check rotation by eclipsing of the individual ones tell you anything interesting? A little bit about the mass distribution by precession maybe? 3ch |
