Title
Asteroid 2006 VV2 flyby on Mar. 2007
Description
Near Earth Object (NEO), Asteroid 2006 VV2
Asteroid 2006 VV2 passed very close to Earth on Mar. 31, 2007 and had a close (visual) encounter with asteroid Psyche
2006 VV2 approached within only 0.023 AU (only 8.8 lunar distances or 3,44 million km) to earth!
Info
According to NASA, 2006 VV2 was discovered by LINEAR on November 11, 2006
It's diameter is estimated between 1,5km and 3km
The Minor Planet Center classified 2006 VV2 as a Potentially Hazardous Asteroid
2006 VV2: 10mag, distance 0.0236AU, solar distance 1.0187AU
(16) Psyche: 10.9mag, distance 2.36AU, solar distance 3.25AU

Step wedge - Graustufenkeil
Info
Please use this step wedge to adjust contrast and brightness-levels of your monitor,so you can see all grey levels from black to white. Especially take care, thatthe blackest black is as dark as possible, but still distinguishable fromthe next brighter step.
Info
Bitte benutzen Sie diesen Grauverlauf, um Ihren Monitor soeinzustellen, daß alle Graustufen von schwarz bis weiß sichtbar sind. Das dunkelste Schwarzsollte dabei so dunkel wie möglich erscheinen, aber trotzdem noch von der nächst hellerenGraustufe zu unterscheiden sein.
