Scientist Warns of Asteroid Danger

A leading astrophysicist from Queen's University Belfast has warned that an asteroid strike is just a matter of time. Professor Alan Fitzsimmons from the University's Astrophysics Research Centre has said it is a case of when an asteroid collision will happen, rather than if it will happen.

Joined by scientist Brian Cox and astronauts such as Apollo 9 astronaut Rusty Schweickart and International Space Station astronaut Nicole Stott, Professor Fitzsimmons is highlighting the threat for Asteroid Day, a global event next Friday (30 June).

On that day in 1908, a small asteroid exploded over Tunguska in Siberia and devastated 800 square miles. Professor Fitzsimmons is warning that a similar unexpected strike in today's world could easily destroy a major city and a larger asteroid could be more dangerous.

Professor Fitzsimmons commented: "It is important to know that scientists and engineers have made great strides in detecting Near-Earth Asteroids and understanding the threat posed by them. Over 1,800 potentially hazardous objects have been discovered so far, but there are many more waiting to be found.

"Astronomers find Near-Earth Asteroids every day and most are harmless. But it is still possible the next Tunguska would take us by surprise, and although we are much better at finding larger asteroids, that does us no good if we are not prepared to do something about them."

The discussions and presentations will be streamed live from Luxembourg on 30 June at https://asteroidday.org/live/ and experts will be answering any questions from followers via social media. Hundreds of supporting events will be held in over 70 countries.

Professor Fitzsimmons is a member of the NEOshield-2 project, funded by the European Research Council to study how to deflect dangerous asteroids.

Queen's University is also a partner in the Pan-STARRS project in Hawai'i - the most successful asteroid hunter currently in operation, as well as the Large Synoptic Survey Telescope project, which will provide a quantum leap in asteroid discoveries.

  1. So what does this mean? Is June 30th just a day of Asteroid Awareness?

    1. Yes, a day to reflect on the subject and reaffirm our commitment to seek and develop a means to mitigate such threats. Currently, we make new discoveries of approaching threats a day before and sometimes even after close approach. We need better.

  2. This natural disaster can be avoided unlike earthquakes or volcano eruptions , it is only a matter of priority and AD is intended to raise the public's awareness and thus raise the priority of this subject for decision makers

  3. OK so an asteroid say 500 meters in diameters will possibly hit the earth in five years time,what by making the public aware of it is it going to benefit them.
    Except for finding all the POA's I have not heard of One concrete proposal that could be put together in that time frame.
    I would be interested to hear of one.
    I think AD is just one big public relations exercise.
