Well it's not as big as Toutatis.
H (Vm) Absolute V-magnitude (in general, smaller H implies larger asteroid diameter).
Toutatis H (vm) = 11.00
MR1 H (vm) = 25.21
So in KM or miles how big are these suckers?
1 AU is the distance from the earth to the moon right? Or is it the earth to the sun?
"Potentially Hazardous Asteroids (PHAs) are currently defined based on parameters that measure the asteroid's potential to make threatening close
approaches to the Earth. Specifically, all asteroids with an Earth Minimum Orbit Intersection Distance (MOID) of 0.05 AU or less and an absolute
magnitude (H) of 22.0 or less are considered PHAs. In other words, asteroids that can't get any closer to the Earth (i.e. MOID) than 0.05 AU (roughly
7,480,000 km or 4,650,000 mi) or are smaller than about 150 m (500 ft) in diameter (i.e. H = 22.0 with assumed albedo of 13%) are not considered PHAs.
