2010 TK7 is a near-Earth asteroid that was discovered on October 5, 2010. It is classified as a quasi-satellite of Earth, meaning it orbits the Sun but is also influenced by Earth's gravity. This unique orbit allows it to remain relatively close to our planet. The asteroid is approximately 300 meters in diameter and takes about 1.5 years to complete one orbit around the Sun. 2010 TK7 is of interest to scientists because studying such objects can provide insights into the early solar system and the formation of planets.
