Asteroids are small planets that fall between the categories of planet and comet. The inner solar system is made up of objects that are in a straight orbit around the Sun. Planetoids are asteroids that are larger than asteroids. These are distinguished from minor planets in the outer solar system by their volatile-based surfaces, which are similar to comets. The asteroid belt is the name given to this region.
This year on International Asteroid Day, we are celebrating the 113th anniversary of the greatest recorded asteroid impact falling on the Tunguska River in distant Russian Siberia. Most asteroids are oddly shaped, according to scientists who research Near-Earth Objects, or NEOs. They're frequently pitted or have little craters. The United Nations General Assembly declared June 30 as International Asteroid Day in December 2016.
The Tunguska incident occurred near the Tunguska River in Russian Siberia, and was a massive explosion. According to accounts, the asteroid's impact was so powerful that it flattened an estimated 80 million trees across 2,150 square kilometres of woodland.
"The only entry of a big meteoroid into the Earth's atmosphere with eyewitness testimonies in contemporary history was the Tunguska event," NASA writes. This meteor landed in a distant section of Siberia but didn't make it all the way to the ground. Instead, it went off a few miles away, exploding in the air. The blast was powerful enough to bring down trees throughout a region hundreds of miles wide... Hundreds of reindeer were slaughtered locally," but there is no evidence of human casualties.
The goal of International Asteroid Day is to promote public awareness about the threat of an asteroid impact and to inform the public about the global crisis communication steps that will be done if a serious near-Earth object threat is detected.
After the Asteroid Foundation was founded in 2017, the Asteroid Day website and activities became an official programme of the organisation. The objective of the Asteroid Foundation is to raise global understanding of the opportunities and challenges that asteroids and the burgeoning space industry present. In addition to the above-mentioned Asteroid Day programmes, the Foundation also organises local events such as the Asteroid Day Gala and Technical Briefings in Luxembourg, as well as a year-round schedule of activities.
Space is a fascinating location to explore and learn about the intricate details of our existence on this planet.
