H=28.7. It's not very big though. Rough conversion is 6 metres.

I've put up Celestia and Sellarium files for 2010 TD54. It's raining here though. http://astroblogger.blogspot.com/201...2010-td54.html

Even if this rock were to hit earth, most would be ablated in the atmosphere. What would hit the ground would be 4m accross if lucky(typically around 90% gets ablated off) Almost all if not all the cosmic velocity would be gone, so an explosion on impact would most likely not occur. So a 4 metre rock hits your roof at terminal velocity of 250m/sec. Yeah, it would make a big mess, but think what you could sell bits of the mass off on ebay for!
Me reckons I could dine out for years on the story. Think of the corny puns- enough to bring the roof down

That's providing it didn't land on the part of the house you were in at the time!

Interesting stat for the "Chicken Little's" of the world...
