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

The ESA SSA-NEO Coordination Centre has released the December newsletter.

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...

The NEOCC provides programmatic access to its data through a set of simple HTTPS GET endpoints that return plain-text responses. No authentication is required. All requests and parameters are...

It is possible to visualise the orbits of all asteroids in our database by entering their name, provisional designation or catalogue number. The position along the orbit is computed at regular time...

The NEOCC is ESA's centre for observing and computing asteroid orbits and assessing their impact risk.

One month ago, NEOCC team ruled out the possibility that asteroid 2006 QV89 would impact the Earth this September by making a “non-detection”, i.e. observing the area of the sky where the asteroid...

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...

The first NEA, (433) Eros, was discovered by Gustav Witt from the Urania Sternwarte Berlin and independently by Auguste Charlois from the Observatoire de Nice, on 13 August 1898. The discovery...

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:...
