Good to seem some life at these boards. This is such a long running project, too.

I'd also like to know this. Furthermore, it would be useful if the running program would automatically flag any asteroids with unusual shapes or extreme aspect ratios and posts a notice somewhere for someone to check it out. Who knows how many weirdly shaped asteroids we could already have calculated shapes for and the data is just sitting there waiting to be mined.

How much does the Yarkovsky effect depend on the overall size of an asteroid?
Is the effect negligible for really large asteroids?

asteroids home is working both: shape and trajectory.
Shape working is called inversion light curve and trajectory is period searching


You are incorrect. See http://asteroidsathome.net/boinc/forum_thread.php?id=12&postid=58#58

If you look what happenned in Russia with the asteroids falling who broke the whole Windows of a city and occured troubles in the city, then it is sure to increse the knoledge of the asteroids to prevent in the future such issues.


As far as I can tell, Asteroids@Home only computes the shape of the asteroids, not their trajectory. Close approach data would be much more useful to prevent disasters such as you mention. Granted, any data of an earth-crossing asteroid including its shape would be useful, however if we discover one to be on a collision course with earth and we don't already have it's 3D model computed I'm pretty sure that particular asteroid would be the highest priority and that data would be ready within minutes! So, apart from increasing scientific knowledge, is the Asteroids@Home data really giving us any advance protection from any possible existential risks?

World Community Grid also has visuals though they're not very interesting.
