The potential to really open a new window into the history of our solar system when Lucy gets to the Trojan asteroids is ...

In 2020, astronomers thought they'd found something incredible: the second so-called Earth Trojan asteroid ever seen. Now, a new team of researchers has confirmed that it's real.

The probe's first encounter will be with the asteroid Eurybates in August 2027. According to NASA, Lucy will conduct four ...

Our planet has a celestial sentry leading the way around the sun, and it’s only the second Earth Trojan asteroid ever discovered. Astronomers observed asteroid 2020 XL5 using the Southern ...

The researchers estimate that the asteroid's size — around 0.7 miles in diameter, which is larger than the previously-discovered Earth Trojan asteroid 2010 TK7's 0.2-mile diameter — will keep ...

Earth has a SECOND 'Trojan asteroid': 1,800ft-wide space rock is trapped in the same orbit as our planet for at least 4,000 years. Earth's second 'Trojan asteroid' has been discovered by a team of ...

Only one other Trojan asteroid has been spotted around Earth. Scientists spotted the new Trojan candidate on December 12, 2020. Data has since confirmed that it is an Earth Trojan after all.

The only other Trojan asteroid seen around Earth, discovered 12 years ago, also at the L4 point, and called 2010 TK7, is smaller, with a diameter of about a quarter mile (400 meters).

Very few asteroids share the orbit of Earth -- just two have been discovered to date -- and astronomers have recently confirmed the existence and size of one. Skip to main content Menu ...

Asteroid 2020 XL5 is around three quarters of a mile across making it larger than the first Trojan asteroid found in Earth's orbit, Trojan asteroid 2010 TK7, which is about a quarter of a mile across.
