Hi-Kim here. This month our “Hot Off the Press” is the article “Asteroid 2011 AG5 – A Reality Check.” This article explains that, while this asteroid has been getting a lot of attention, it only ranks as a 1 on the Torino Impact Hazard Scale. The Torino Scale helps to rate the hazards that various objects pose to Earth. “1” on the scale means, in part that, “Current calculations show the chance of collision is extremely unlikely with no cause for public attention or public concern.” The article goes on to say:
“2011 AG5 will next be near Earth in February of 2023 when it will pass the planet no closer than about 1 million miles (1.6 million kilometers). In 2028, the asteroid will again be in the area, coming no closer than about 10.4 million miles (16.7 million kilometers). The Near-Earth Object Program Office states the Earth's gravitational influence on the space rock during these flybys has the potential to place the space rock on an impact course for Feb. 5, 2040, but this has very unlikely odds of occurring at 1-in-625.”
"Again, it is important to note that with additional observations next year the odds will change and we expect them to change in Earth's favor.” So we are safe…for now ;).
