Will we be ready to face a real asteroid threat in the next hundred years?

Scientists know for sure that it is constantly happening and that the risk of a collision between a NEO and Earth is high. The question is not if it will happen one day, but when it will happen and how we are going to react to this threat. A few decades ago, many countries have realised that it is our
Asteroid 2015 KW 120 will make a really close approach with Earth tomorrow!

The NEO has an estimated diameter of 11-36 meters (H= 26.0) and will speed past us at 13 km/s (approximately 46800 km/h), at only 1.1 Lunar Distances [LD] – about 422400 kilometers – from our planet. Asteroids make close approach with Earth every day, but this one will pass by really close. However, there
Sentinel may be able to detect smaller asteroids!

Indeed, smaller NEOs are much more likely to hit Earth in the following years, than larger NEOs. Everyone still remembers the Chelyabinsk meteor that injured more than a thousand people in
Is it a bird? Is it a plane? Is it an asteroid???

This morning, one of the MPC’s staff members posted a description of the so-called moon, also named 2015 HP116. The small asteroid was supposed to orbite our planet until March 2019. Unfortunately, the news was disclaimed a few hours later, when
