Atmospheric heating is nonexistent on asteroids. Inserting the probe exactly in the path of small asteroid might be a problem…. This is a collision at 46, Do you think you could create big enough air bags that could cushion the impact?

Thanks for the numbers! Imagine technology withstanding g, which is a realistic figure as I understand. And that means you need 2. So the breaking path is 17 km? There has to be a way how to get a free ride! Since you would be wearing a spacesuit I presume the molecules would be confinged to the suit. Image link. Olaf, space has no friction. Sci-fi shows seem to have everyone brainwashed to forget this factor.

This is why we have calculus…. Yes then use your calculus to calculate how much fuel you would need to match the asteroids speed. Now calculate the speed how much you would need to have the same orbit like that asteroid would have without asteroid. It is the exact same orbit. What do we fear? When you lose your fear of death, and loss, fear no longer controls you. The thermal properties seem to be very similar to the ones found for Itokawa, a small body visited by the Japanese mission Hayabusa , which turned out to be a rubble pile.

Our findings indicate that YU55 might also be a loose assembly of boulders, pebbles and dust and not a single monolithic rock in space. The Herschel observations also help to improve the orbit calculations of YU5. The minor planet does not pose a danger for Earth, at least within the next few decades, for which we can predict its orbit with high accuracy. In this little asteroid will have a close encounter with Venus at km , afterwards the orbit is not perfectly predictable and it is unlikely that YU55 will cross the Moon's orbit again in In case of YU55 we can rest assured that we are safe for the next few decades.

And, instead of working out deflection concepts, we can concentrate on the more scientific aspects of characterising this exotic and very interesting minor body.
