The fly-by of 2020 JJ asteroid

The number of known near-Earth asteroids (NEAs) reached the round total of 20 000 this week. This family of asteroids whose orbit brings them close to Earth is steadily growing at a pace of roughly...

Last month, ESA's near-Earth asteroid coordination centre triggered a series of European observations that confirmed an unknown object was, in fact, of human origin. The confirmation was the...

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 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...

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. 

On 19 October the Pan-STARRS telescope, one of the NASA-funded surveys dedicated to discovering new NEOs, found an object that proved to be extremely unique: for the first time, an asteroid...

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...

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...

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...
