Spotting asteroid Florence

Asteroid 3122 Florence was discovered in 1981. It’s named in honour of Florence Nightingale (1820-1910), the founder of modern nursing. With a diameter of ~4.3 km, Florence is among the largest of the near-Earth asteroids. ESA’s Rüdiger...

Asteroid 2014 KC46 was rediscovered by the Large Binocular Telescope (LBT) on 28 and 30 November 2014. At magnitude 26.3, it is one of the faintest Near-Earth Object (NEO) recoveries ever performed.

Found: One of the faintest-ever asteroids

The Large Binocular Telescope (LBT), of which the Italian National Institute for Astrophysics (INAF) is a main partner, successfully observed asteroid 2014 KC46 in the nights of 28 and 30 October 2014.

Earlier in October, the main ESA web site carried an article announcing the delivery of the Agency’s new debris test radar to its site close to Madrid: ESA deploys first orbital debris test radar in Spain 15 October 2012 A new radar designed to test methods for finding orbital debris that can be hazardous to space navigation has been installed in Spain. The radar will be used to develop future debris warning services, helping to boost safety for European satellite operators. (Background details on ESA’s Space Situational Awareness (SSA) programme) The news is interesting from several aspects. First, it’s the first of a pair of radars that will be used by the...
