On 3 March 2013, the Catalina Sky Survey discovered 2013 ET, a small asteroid with an estimated size around 100 meters. This cosmic rock is approaching our planet and on 9 March at 12:09 UT will reach a minimum distance from the Earth of a bit less than one millions of km, about 2.5 times the distance of the Moon. Of course, there are no risks at all for our planet, as usual it will be nice to spot this fast moving object while it crosses the winter skies.
The Virtual Telescope will offer a public, free online observing session of this asteroid next 8 Mar. 2013, at 19:00 Universal Time. As usual, real time images will be made available on our webTV, with the live commentary of the astrophysicist Gianluca Masi, PhD.
