See the Trojan asteroid and Earth orbit

The Earth is not alone in its orbit around the Sun but also has a small Trojan asteroid located in front of our planet.

This discovery was published on July 28 in the British Journal of Nature.

This small asteroid is only 300 meters in diameter but is called a Trojan because its special location is on a fixed point either in front of or behind a planet. Because this asteroid and the Earth are constantly in the same orbit, they never collide.

Jupiter, Mars and Sao Hai Vuong also have Trojan asteroids that orbit with them, similar to Saturn's two moons.

Scientists from the US National Aeronautics Agency (NASA) discovered the asteroid, 80 million kilometers from Earth, using the Wide-field Infrared Survey Explorer (WISE) telescope.

Astronomers have long argued that the Earth has some Trojan asteroids but their findings are somewhat confusing because it is difficult to observe Trojans during the day.
