A recent study suggests that Earth's tiny asteroid visitor, known as 2020 SO, is likely a chunk of the Moon that was ejected into space by an impact event. This diminutive guest was first observed in September 2020, with its orbit around the Sun being so similar to Earth's that scientists initially thought it might be a piece of space junk. However, further research has pointed towards a more natural origin.
The research team used the Large Binocular Telescope (LBT) in Arizona and the Neil Gehrels Swift Observatory in space to gather data about 2020 SO. They discovered that the sunlight reflecting off this object was similar to that of lunar rocks, suggesting a common origin. The team believes that an impact event on the Moon around 2-3 billion years ago may have sent this piece of lunar rock into space, where it eventually fell into an Earth-like orbit.
This study provides valuable insight into the nature and origins of Asteroids, as well as the dynamic processes that shape our solar system. The discovery also highlights the importance of continuous monitoring of near-Earth objects, as they can offer unique opportunities for scientific investigation.
While 2020 SO is expected to leave Earth's vicinity in March 2021, the data gathered from this small Asteroid will continue to inform our understanding of the Moon's history and the broader dynamics of our Solar System. As we continue to explore the cosmos, every piece of the puzzle brings us closer to comprehending the vastness and complexity of the universe around us.
Overall, the study of 2020 SO serves as a reminder of the immense value of scientific curiosity and the ongoing quest for knowledge. It underscores the importance of using advanced Astronomy techniques and technologies to uncover the secrets of our celestial neighbors and to continue expanding our understanding of the universe.
