On Tuesday, an international group of asteroid experts assembled to talk about the future of asteroid research and avoidance, getting all set for the second annual Asteroid Day.

A huge meteorite or comet exploded over the distant Russian countryside, destructing 770 square miles of forest on June 30, 1908. In observance of the same, June 30 is now called Asteroid Day, part of a campaign to make more and more people aware regarding the dangers of an asteroid strike on our planet.

On February 9, during a press conference the organizations behind Asteroid Day made an announcement sharing their plans for the latest effort. They invited a panel of experts to discuss the requirement of further study of asteroids and to talk about a commitment to prevent a huge body from hitting the Earth. The event took place at the European Space Research and Technology Centre (ESTEC).

The researchers said that strikes from asteroids and comets huge enough to threaten people are not common in any given year however, with the passage of time they are just about inevitable. For example, a meteor fell near Chelyabinsk, Russia on February 13, 2015, exploding nearly 18 miles above the surface of Earth. The shock wave broke windows, causing injuries to 1,500 people.

During the conference, Mark Boslough, a physicist at Sandia National Laboratories who is among the founders of Asteroid Day, said that an event like Chelyabinsk happens about once in every half century, and they don’t have a system ready to find and track such events.

One of the organizers of Asteroid Day, Brian May, an astrophysicist and ex guitarist for the rock band Queen said that concerted efforts are required to detect asteroids that could collide with our planet, and to send spacecraft for studying them.
