Soon after having been spotted in the sky on 8 October 2013 from the Crimean Astrophysical Observatory (Ukraine), asteroid 2013TV135 topped the Risk Page. Being a relatively large object (500 m in...

On 8 November 2013 asteroid 2013 TV135 has been removed from the Risk Page. The non-zero impact probability spotted by monitoring systems just after its discovery (on 8 October 2013) dropped...

If an asteroid is discovered which could come very close to Earth, it is important to coordinate observational activities quickly to better know its precise flyby distance.This is illustrated by...

The first recovery campaign carried out by the ESA NEO Coordination Centre in coordination with ESO, using the Very Large Telescope (VLT) (VLT telescopes on the Paranal mountain in Chile (credit:...

A team of European astronomers has found a previously unknown comet, detected as a tiny blob of light orbiting our Sun deep in the Solar System.

After discussing what to do to ensure that an important NEO is adequately monitored (see "news archive"), we will now present a possible strategy to improve the orbit of old objects, that have not...

The observational component of NEO science is an extremely important part of the impact mitigation effort, since observations are the input data for all the computational models used to predict...

The ESA Optical Ground Station has quickly become a major asset for the NEO Coordination Centre, thanks to the many nights devoted to observing asteroids. It is located at an altitude of 2400 m on...

Spotting Earth-threatening asteroids is tough partly because the sky is so big. But insects offer an answer, since they figured out long ago how to look in many directions at once.

Each year, astronomers worldwide discover over 1000 new asteroids or other space rocks that could strike our planet. And if one is spotted heading towards Earth, experts working in ESA and national...
