Earth's second 'Trojan asteroid' — a space rock that shares the same orbit around the sun as a planet — has been discovered by astronomers. Prior to the detection of Earth's first Trojan asteroid in 2010, the space rocks had only been spotted at Jupiter, Neptune and Mars.This second example, named 2020 XL5, will remain trapped in the same orbit as Earth for at least 4,000 years, according to an international team of researchers.
