Today is the 3rd annual Asteroid Day, and the first to be presented under the auspices of the United Nations, with live global programs raising awareness about asteroids

Today, more than 1,000 local affairs in around 200 countries are being organised to celebrate Asteroid Day. Sanctioned by the United Nations in 2016, it is a global day of education to raise awareness about asteroids.

In addition to the local contests, a day-long program will be transmitted from around the world, with a six-hour live elongate “re coming out” Luxembourg. This is where I will be, sharing the hosting imperatives with Professor Brian Cox from 11 am BST. You can watch the whole thought in the video embedded above.

My association with Asteroid Day began with telephone calls from film-maker Grig Richters one afternoon in 2014. I knew Grig and had worked with him on his movie, 51 North , drama about the damaging collision of an asteroid with Earth.

On the phone that afternoon, he told me that he wanted to set up a period to sensibly transmit the risk of being asteroids and why it needed a world reaction. This reverberated with me because the UK Governments Asteroid Task Force, from 2001, had recommended structure world collaboration to tackle the issue.

Grigs co-founders for Asteroid Day were Brian May, Queen guitarist and astrophysicist, Rusty Schweickart, Apollo 9 astronaut, and Danica Remy of B612, a non-profit organisation that seeks to harness the capability of science and technology to shield the future of our planet.

Thanks to their efforts, Asteroid Day was a success from the beginning but this year the number of events is doubled that from one year ago, and four times as many as during the course of its inaugural Asteroid Day in 2015.

Asteroid Day makes place on 30 June because on the working day in 1908, a small celestial body disturbed an uninhabited arena of Siberia, Russia. The bomb ravaged 770 sq miles( 2,000 sq km) of timber. Thats more than enough to destroy a entire municipal should one be struck.

Around the world, space the institutions and two organizations are working towards understanding and eventually keeping Clay from this hazard. This burgeoning global alliance is what is being celebrated today.

Space has always had an uncanny ability to unite parties regardless of their political, national or theological disagreements. Asteroid Day sounds into that, promotes it and hopefully promotes it.

To take part in Asteroid Day, wherever you are, watch the live feed in the viewer above and post any relevant questions for the experts in specific comments below. We will be searching them during the day.
