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 discovering a new and exceptional object.
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 would appear if it were on a collision course with our planet - and not detecting it.
On 25 July, an asteroid the size of a football field flew by Earth, coming within 65 000 km of our planet’s surface during its closest approach – about one fifth of the distance to the Moon.
