NASA has received unique recordings of the SD220 asteroid in 2003, which will be passing near the Earth this Saturday, and discovered that the celestial body has the form of a nil horse.
The asteroid will go "near" to our planet, at a safe distance of 2.9 million kilometers, which will be its closest approach to Earth for more than 400 years.
Thanks to the radar images obtained from the three huge NASA antennas installed in different parts of the United States, it has been found that this stone body has approximately 1,6 kilometers of length and a shape similar to that of the "nilski" river, "seen from the air.
It has also been shown that the 2003 SD220 has an "extremely slow" rotation period of about 12 days on a complex axis of rotation. These new details will make it possible to "better understand how these small bodies were formed and evolved over time," scientists from the US space agency say.
This asteroid was discovered in 2003 and is classified as potentially dangerous due to its size and predictable access to our planet. However, new data reveal that this is not a threat to the Earth, NASA concluded.
