The “mini moon” on Earth, which might be a portion of the real moon, won’t be visible until 2055.
A small asteroid, called Earth’s “mini-moon,” will soon leave its orbit and head toward the sun. Known as 2024 PT5, the asteroid has been near Earth since September. It is expected to disappear from view until 2055.
Origins of 2024 PT5
Astronomers believe the 33-foot-wide asteroid may be a lunar boulder. It was likely ejected from the moon centuries ago after an asteroid impact. Unlike other objects, 2024 PT5 never came close enough to be captured by Earth’s gravity.
NASA has confirmed that the object is natural, not man-made. Its motion resembles Earth’s orbit, further suggesting a lunar origin. Josh Handal from NASA’s Planetary Defense Coordination Office noted that its characteristics make it unlikely to be debris from past rocket launches.
A Temporary Visitor
Since September, the asteroid has followed a unique, horseshoe-shaped path around Earth. It remained at a safe distance of 2 million miles. However, in January 2024, it will pass as close as 1.1 million miles. This will mark its closest approach before the sun’s gravity pulls it deeper into space.
The asteroid’s speed will increase significantly during its January flyby. NASA will track it using the Goldstone solar system radar in California. Scientists hope to gather valuable data during this brief encounter.
Return in 2055
After completing an orbit around the sun, 2024 PT5 is expected to return in 2055. When it does, it will once again temporarily orbit Earth before continuing on its path.
