The End of the World: An Update
For all you post-humanists who are looking forward to major life extension breakthroughs in the next century, be advised that asteroid 2004 VD17 has a 1 in 500 chance of impacting Earth on May 4, 2102. Prepare accordingly. Personally, I recommend consciousness uploading to a quantum databank buried deep beneath Olympus Mons.

Thanks for the heads-up. I'll tell Erika.
Well, it could be even less than that. Given the specs in the article, I come up with a number much lower than the one you cite from Wikipeida.
500m diameter shpere = 15.6x10^15 cm3
1 billion tons = 0.9x10^15 grams
Works out to a density of 0.058g/cm3 does it not?
Less than a space marshmallow?
