An asteroid with us on our trip around the sun


Astronomers detected an asteroid which follows the orbit of the Earth around the sun. The rock-between 200 and 300 meters in diameter and 2010 TK7-christened it the Trojans, which are those that share an orbit with a planet near stable points. Because they remain in front of or behind the planets in the same orbit, never collide with them.

According to the science specialist for the BBC, Jonathan Amos, it is a fascinating finding because the relative stability and proximity of the Trojan asteroids makes them potential targets for future space missions, when they go beyond the International Space Station (EEI).
