Explanation:

International Asteroid Day 2020 is being celebrated on 30 June. In 2016 the United Nations General Assembly adopted resolution A/RES/71/90, declaring 30 June as International Asteroid Day. It is observed each year to mark the anniversary of the Tunguska impact over Siberia, Russian Federation, on 30 June 1908, and to raise public awareness about the asteroid impact hazard. The Tunguska asteroid event in Siberia, Russian Federation, on 30 June 1908, was the Earth's largest asteroid impact in recorded history. Near-Earth objects (NEOs) represent potentially catastrophic threats to our planet. NEO is an asteroid or comet, which passes close to the Earth's orbit. According to NASA’s Center for NEO Studies, there are over 16 000 Near Earth Asteroids discovered. Hence all statements are correct.
