[bjorkstrand]

2010 FX86 tno was announced today in the daily planet update.
SO far it may be bigger than Varuna with an H=3.1. Period=292 years Arc indays =18
Observations =6
Maybe it will be named.

With such a short arc, it's still far too early to make any definative statements about it's final H or classification as a cubewano.

Still, it might be big
