Asteroid or angel-like UFO?
When comet-like asteroid P/2010 A2 first appeared to skywatchers in 2010, observers were quick to point out the mysterious X-shaped form racing through the skies. It is seen here as viewed by the Hubble Space Telescope. The X-shape is merely a “debris pattern” that suggest a head-on collision between two asteroids, says NASA. Nonetheless, the object — some 180 million miles from the sun and 90 million miles from Earth — caused quite a bit of excitement among alien enthusiasts. But in general, the government concludes that 90 percent of the UFO sightings are attributed to astronomical or meteorological phenomenon.
