They snuck this one in, it wasn´t on the list yesterday. You have to watch the list for changes, it can change every day.

Given the estimated size of only 10-23 meters, perhaps it was just discovered.

(2005 VN5) 2005-Nov-12 0.0035 1.3 10 m - 23 m 6.58

[link to liftoff.msfc.nasa.gov]

Parameters:

Distance from Impact: 1.00 km = 0.62 miles
Projectile Diameter: 23.00 m = 75.44 ft = 0.01 miles
Projectile Density: 3000 kg/m3
Impact Velocity: 6.85 km/s = 4.25 miles/s
Impact Angle: 45 degrees
Target Density: 2750 kg/m3
Target Type: Crystalline Rock

Energy:

Energy before atmospheric entry: 4.48 x 1014 Joules = 107.12 KiloTons TNT
The average interval between impacts of this size somewhere on Earth is 19.7 years
Atmospheric Entry:
The projectile begins to breakup at an altitude of 39500 meters = 129000 ft
The projectile bursts into a cloud of fragments at an altitude of 16500 meters = 54000 ft
The residual velocity of the projectile fragments after the burst is 3.57 km/s = 2.21 miles/s
The energy of the airburst is 3.27 x 1014 Joules = 0.78 x 10-1 MegaTons.
No crater is formed, although large fragments may strike the surface.

Could destroy a city with a direct hit, but unlikely.

hi Die Bunker,

Interesting!

From the first link you gave:

Each day as many as 4 billion meteoroids, most miniscule in size, enter earth´s atmosphere. Most of these meteors burn up from atmospheric friction and never reach the ground. Only a few larger and more dense meteors reach the earth´s surface and make an impact.

damned 4 Billion a day? Good Gravy! No wonder Informer (I think it was) always said...

WATCH THE SKIES...SOON!

LD = Lunar Distance
1.3 means it will pass a little farther away than the moon

that is close

This oneīs orbit runs close to the elliptic, just inside Venusīs orbit to just outside Earthīs orbit. Thereīs another close approach to the Earth in Jul 2013, and another in jul 2022. It also has three close calls with Venus before 2022. Wouldnīt all these close calls effect itīs orbit???

You are always wrong. As you did not specify that an asteroid would pass by, donīt pretend that you meant it. If you had known about it, you would have told us it was an asteroid.
