NASA photographed stadium-sized asteroid OS7 approaching Earth in 2008. What was the risk?

deep space network, planetary radar POT collected the first detailed images of an asteroid 2008 OS7,stadium size, using his approach to Earth

February 2, 2024this large asteroid passed close to Earth at a distance of approximately 2.9 million kilometers, or 7 and a half times the distance between Earth and Moon.

There was no risk that asteroid 2008 OS7 would collide with our planet, but scientists from NASA Jet Propulsion Laboratory They used a powerful radio antenna to better determine the size, rotation, shape and surface details of this object. NEO (near-Earth object). Before this approach appeared asteroid 2008 OS7 was too far from Earth for planetary radar systems to image it, reports POT.

An asteroid has been discovered July 30, 2008during routine search operations October through Overview of the Catalina sky.

Following its discovery, observations of the amount of light reflected from the asteroid’s surface showed that it was approximately 200 to 500 meters wide and that it rotated relatively slowly, making one rotation every 29 and a half hours.

During a close approach February 2JPL’s radar team used a powerful satellite dish 230-foot (70-meter) Goldstone Solar System Radar at the city’s facilities Deep Space Network near Barstow, Californiato obtain images of the asteroid.

Scientists have discovered that its surface consists of rounded and more angular areas with a slight concavity. They also discovered that the asteroid is smaller than previously thought. (width about 150-200 meters)

and confirmed its unusually slow rotation.
