Also known as International Asteroid Day, World Asteroid Day is celebrated on 30 June to spread awareness in public about the asteroid impact hazard. There are over one million asteroids in space that could potentially strike the earth, but modern scientists have only discovered about one percent of them. The United Nations General Assembly in December 2016 adopted a resolution A/RES/71/90 and designated 30 June as International Asteroid Day. The date of June 30th was selected as it marks the anniversary of the Tunguska event. The above stamp is 43 pennies stamp issued in the year 2009. Guernsey produced a set of six stamps for IYA under the title “400th Anniversary of the Telescope”. The stamp is based on the images seen through the telescope of the Italian scientist Galileo Galilei. Image Courtesy: colnect.com
