A miss is as good as a mile - but this asteroid is a very close shave

The asteroid - which goes by the catchy name of 2012 DA14 - will miss our home planet by just 17,200 miles, which is a very near miss in space terms. The asteroid, which is about 150ft across, will come closer to Earth than the ring of geosynchronous satellites, which are in orbit about 22,200 miles above the Earth. Space rock: Although it will come uncomfortably close to the Earth, the asteroid will only be visible if you have a good pair of binoculars On June 30 1908, in a remote part of Russia, a fireball was seen streaking across the daytime sky. The explosion registered on seismic stations across Eurasia. Asteroids and Comet Watch.

Follow @universetoday on Twitter A newly found asteroid, 2013 EC can be seen in the lower left corner of the red box in this image. Screen capture from Virtual Telescope webcast on 3/3/2013. A newly found asteroid will pass just inside the orbit of the Moon, with its closest approach on March 4, 2013 at 07:35 UTC. Named 2013 EC, the asteroid is about the size of the space rock that exploded over Russia two and a half weeks ago, somewhere between 10-17 meters wide. 2013 EC was discovered by the Mt. 2013 EC will come within 396,000 kilometers from Earth, (246,000 miles, or around 1.0 lunar distances, 0.0026 AU. The Moon’s distance from the Earth varies between 363,104 km (225,622 miles) at perigee (closest) and 406,696 km (252,088 miles) at apogee (most distant point). Gianluca Masi from the Virtual Telescope Project had a live view of the asteroid when it was about twice the distance of the Moon, and a replay of that webcast is available below.

2013 Meteor Showers

Bright moonlight makes it difficult to see all but the brightest meteors. What is a meteor shower? A meteor shower is a spike in the number of meteors or "shooting stars" that streak through the night sky. Most meteor showers are spawned by comets. As a comet orbits the Sun it sheds an icy, dusty debris stream along its orbit. Meteor showers are named for the constellation that coincides with this region in the sky, a spot known as the radiant. What are shooting stars? "Shooting stars" and "falling stars" are both names that describe meteors -- streaks of light across the night sky caused by small bits of interplanetary rock and debris called meteoroids vaporizing high in Earth's upper atmosphere.

When a meteor appears, it seems to "shoot" quickly across the sky, and its small size and intense brightness might make you think it is a star. 2013 Meteor Showers.
