Largest-ever asteroid is about to fly by Earth

September 1. 18 LDs away, so should be fine. At 4.6 km dia, it would do more than just muss our hair...
Not to worry, wont be back for 483 years

18 LDs?

LDs is Lunar Distance. Basically how far away the moon is away from us.

Oh thank you! I was scratching my head wondering what it meant! :oops:

1 LD = about 400,000 km
When they start using fractions of LD, then it's serious

It's also easier to express for some, 7.2 million km might not get noticed, or something. Heaven help them if they start using light-seconds for things :mrgreen:
