Asteroid will become a satellite of Earth for two months. The Earth's gravitational pull will capture asteroid 2024 PT5 from the secondary asteroid belt Arjuna, and it, like the Moon, will orbit our planet - but for only 56.6 days. The asteroid is about 10 meters in diameter. 2024 PT5 was discovered by researchers at the NASA-funded Asteroid Monitoring System in August this year. Scientists from the Complutense University of Madrid tracked the asteroid's orbit for 21 days and determined its future path - 2024 PT5 will orbit the Earth from September 29 to November 25. Earth's gravity will pull 2024 PT5 into its orbit, and the asteroid itself will not be able to escape our planet's gravitational force. It will orbit around for almost two months, after which it will return to the asteroid belt. But in about 30 years - in 2055 - 2024 PT5 will return to our orbit.
