SSA is the acronym of ESA's "Space Situational Awareness" programme, which was the precursor to the current Space Safety Programme. SSA ran between 2009 and 2019. More info at:...

The Torino scale is a function of the impact energy and probability of the event, with no reference to the time of impact. In the Palermo scale, the risk posed by a possible impactor is compared to...

S2P is the acronym for ESA's "Space Safety Programme”. Its aim is "the protection of our planet, humanity and assets in space and on Earth from dangers originating in space". More info at:...

PDO is the acronym of ESA’s Planetary Defence Office within its Space Safety programme (S2P). The goals of the Office are to: 1) be aware of the current and future position of near-Earth objects...

The possibility of browsing through the largest possible set of astronomical images and download them for inspection is extremely useful in order to find possible unidentified detections of NEOs or...

In the last observing slot at ESA's 1-m telescope on Tenerife, the previously 'lost' object 2009 XZ1 has been recovered. E. Schwab (Germany) has planned and analyzed the observations. The Minor...

NEO Coordination Centre's observing campaign to track the fly-by of BepiColombo

ESA's NELIOTA project detects the flash of light produced when an asteroid collides energetically with the lunar surface and recently recorded its 100th impact.

Planetary Defence office we took the opportunity of the Solar Orbiter launch to perform an observational exercise, attempting to image the departing spacecraft with a ground based optical telescope.

The year has just started, and we already have a very interesting discovery of a new and so far unique asteroid.

If you check our current risk list, you will notice that a significant number of objects in the top positions are extremely “old”, discovered in the first decade of the century.

Over the past week, the Near-Earth Object (NEO) community in general, and ESA’s NEO Coordination Centre (NEOCC) in particular, have been involved in an interesting example of the process of...

Asteroid 2006 QV89, a small object 20 to 50 meters in diameter, has been in the news lately, because of a very small 1-in-7000 chance of impact with the Earth on 9 September 2019.
