Earth volition get a 2nd moon for astir 2 months this twelvemonth erstwhile a tiny asteroid begins to orbit our planet. The asteroid was discovered successful August and is acceptable to go a mini-moon, revolving astir Earth successful a horseshoe signifier from Sept. 29 to Nov. 25.
Researchers astatine the Asteroid Terrestrial-impact Last Alert System, an asteroid monitoring strategy funded by NASA, spotted the asteroid utilizing an instrumentality successful Sutherland, South Africa and labeled it 2024 PT5.
Scientists from the Universidad Complutense de Madrid person tracked the asteroid's orbit for 21 days and determined its aboriginal path. 2024 PT5 is from the Arjuna asteroid belt, which orbits the sun, according to their study published successful Research Notes of the AAs.
But Earth's gravitational propulsion volition gully 2024 PT5 towards it and, overmuch similar our moon, it volition orbit our satellite — but lone for 56.6 days.
While different non-Earth objects, oregon NEOs, person entered Earth's orbit before, immoderate don't implicit afloat revolutions of Earth. Some, however, bash and go alleged mini-moons.
An asteroid called 2020 CD3 was bound to Earth for respective years earlier leaving the planet's orbit successful 2020 and different called 2022 NX1 became a mini-moon of Earth successful 1981 and 2022 and volition instrumentality again successful 2051.
2024 PT5, which is larger than immoderate of the different mini-moons, volition besides instrumentality to Earth's orbit — successful 2055.
Earth's gravity volition propulsion it into its orbit and the asteroid volition person antagonistic geocentric energy, meaning it can't flight Earth's gravitational pull. It volition orbit astir Earth successful a horseshoe signifier earlier reverting backmost to heliocentric energy, meaning it volition rotate astir the prima again, similar the different planets and NEOs successful our galaxy.
Even aft it leaves orbit, it volition enactment adjacent Earth for a fewer months, making its closest attack connected Jan. 9, 2025. Soon after, it volition permission Earth's vicinity until its way puts it backmost into our orbit successful astir 30 years.
The study's pb writer Carlos de la Fuente Marcos told Space.com the mini-moon volition beryllium excessively tiny to spot with amateur telescopes oregon binoculars but nonrecreational astronomers with stronger tools volition beryllium capable to spot it.
CBS News has reached retired to Marcos for further accusation and is awaiting response.
