One of the major goals of the ESA NEO Coordination Centre is to focus observations on objects with non-zero impact probabilities. When an asteroid quickly becomes very faint just after discovery...
An object discovered on 3 October 2015, temporarily designated WT1190F by the observers, will enter the Earth's atmosphere on 13 November. It was discovered by the Catalina Sky Survey...
​​​​​​The impact of WT1190F in the Indian Ocean on 13 November (see our news item on 22 October) provided an excellent opportunity to simulate the observational sequence that needs to be triggered...
Asteroid 2016 RB1 has hit the news because of a peculiar close passage on 7 September 2016 at 19:20 CEST. About the size of a cottage, the asteroid flew past our planet at an altitude of 34000 km,...
The number of known near-Earth asteroids (NEAs) has just surpassed the threshold of 15000. That is a 50% increase over the number known in 2013, when we posted a similar news item on our portal for...
The word "precovery" has entered the astronomical jargon rather recently but it quickly grew in popularity among asteroid hunters. It refers to the finding of an archival observation of an object...
NELIOTA is an activity initiated by the European Space Agency (ESA), which was recently launched at the National Observatory of Athens. The project aims to count and characterise the number and...
An international campaign has revealed that an asteroid will come within 44 000 km of our planet in October, providing a rare opportunity for intensive studies. Astronomers recently spotted...
As part of an international observing campaign, the OSIRIS-REx spacecraft has been imaged during our normal monthly observing run on 16 September with the OGS telescope in Tenerife. In the attached...
A few weeks ago the Pan-STARRS survey discovered a new NEO, temporarily identified as P10G8tt and then formally designated 2018 AM12. Follow-up observations over the next few days allowed the...
During the first month of 2018 two objects reached a Torino Scale level of 1, and attracted the attention of observers with the goal of collecting additional observations necessary to remove the...
At approximately 09:30 UT on 14 April 2018 the Catalina Sky Survey, in Arizona, discovered a bright magnitude 15 object moving at a sky speed of 10" per minute, in the constellation Libra. ...
Every few hours observing the Moon, ESA’s ‘NELIOTA’ project discovers a brilliant flash of light across its surface – the result of an object hurtling through space and striking our unprotected...
