It appears that planet Earth has assumed babysitting duties for a minor space object that came too close to our world and chose to stay for a few weeks. The traveling object fell into Earth’s orbit in September and will remain there until late November. Rocky in disposition and roughly the size of a school bus, the object is an asteroid, yet scientists are calling it a “second moon.”
Traveling along a horseshoe-shaped path through the solar system, this asteroid is classified as a near-Earth object, or NEO. There are many NEOs in outer space. While making a flyby close to Earth, this particular object’s gravitational energy temporarily fell to negative levels, according to a study published by the American Astronomical Society. This implied that it was in Earth’s orbit.
On Sept. 29, it became official. The NEO got caught in Earth’s orbit, technically making it a second moon. It was named 2024 PT5. However, it won’t last long; the rock won’t even revolve once around the Earth before hurtling off in a few weeks.
Although technically a “moon,” the object measures only 33 feet long, roughly 345,000 times smaller than our permanent lunar satellite. Most people won’t see it, as it will be far too small for human eyes or amateur equipment to spot. Astronomers will be able to observe it using high-powered telescopes, Live Science writes. […]
