Hazardous Asteroid went Undetected this week towards Earth 2021 SG
In recent news, the asteroid 2021 SG, comparable in size to a Boeing 747, made a close approach to Earth on September 16, 2021, without any prior detection by scientists. This incident highlights significant challenges in monitoring Near-Earth Objects (NEOs) due to their unpredictable trajectories and the existence of "blind spots," particularly from the direction of the Sun.
### Key Details About the Asteroid:
The event raises critical questions about our planetary defense systems and the necessity of improving detection mechanisms to ensure that we can identify dangerous asteroids before they become a risk. As NASA and other agencies strive to catalog 100% of NEOs, incidents like the one involving 2021 SG remind us that many may still slip through the cracks.
What are your thoughts on this? Do you believe the current monitoring systems are sufficient, or should more resources be dedicated to enhancing asteroid detection?

### Key Details About the Asteroid:
- Size and Comparison: 2021 SG’s dimensions were reported to have a wingspan similar to that of a Boeing 747 and a height akin to Cinderella Castle at Disney World, approximately half the size of the Great Pyramid of Giza.
- Close Encounter: The asteroid passed Earth at about half the distance to the Moon, making it a notably close call. Its closest approach occurred at 9:28 PM Irish time while it was traveling near Greenland and Canada.
- Speed: Traveling at an astonishing speed of approximately 85,748 km/h (23.8 km/s), had it collided with Earth, the impact could have resulted in significant destruction.
- Detection Issues: The key reason for the oversight in detecting 2021 SG was its trajectory coming from the Sun, which obscured it from Earth-based observation systems. This incident underlines the ongoing challenges in identifying and tracking all potential NEO threats.
