“En diciembre de 2016, la Asamblea General de
las Naciones Unidas adoptó la Resolución A/RES/71/90.
Se declaró el 30
de junio como el Día Internacional del Asteroide.
Esto con el fin de celebrar
cada año a nivel internacional el aniversario de la colisión de Tunguska sobre Siberia, Federación de Rusia, el 30 de junio de 1908.

A la vez sensibilizar a la
opinión pública sobre el peligro de una colisión de asteroides

"What Will Happen in 2029 ?" https://science.nasa.gov/solar-system/asteroids/apophis-facts/
On April 13, 2029, Apophis and Earth, each following its own orbit around the Sun, will pass each other at a close-approach distance of only 20,000 miles (36,000 kilometers). There is no danger to Earth, to anyone or anything living on it, or to astronauts or satellites in space. But the event is an amazing and totally unprecedented opportunity to learn much more about Apophis and similar near-Earth asteroids. An asteroid this large passes this close to Earth only every few thousand years on average, so it’s likely that an event like this has not happened at any time in recorded human history. Without a doubt this is the first time it’s happened when humans have had the technology to observe it.
The most important thing happening in this event is that Apophis will be pulled, twisted, stretched, and squeezed by the gravity of Earth as it goes by, in a way that happens only during a very close encounter. The overall pull will change Apophis’s orbit around the Sun, making the orbit slightly larger and giving it a longer orbital period. The twist will very probably change the way Apophis rotates, speeding up or slowing down its spin and changing its orientation. And the stretching and squeezing may possibly cause some small landslides or other movement of surface material on the asteroid, most likely in places that are already steeply sloped. Exactly how Apophis responds to these disturbances will depend on its internal structure and the materials it’s composed of. So by observing and measuring those responses, scientists will be able to work backwards and figure out what is going on inside the asteroid.
