New Earth Trojan asteroid
is the second transient Earth Trojan asteroid known to date, and everything indicates it will remain Trojan -- that is, it will be located at the Lagrangian point -- for four thousand years, thus it is qualified as transient. The researchers have provided an estimation of the object bulk size , and have made a study of the impulse a rocket needs to reach the asteroid from Earth.
The low success in these searches can be explained by the geometry of an object orbiting the Earth-Sun Las seen from our planet. These objects are usually observable close to the sun. The observation time window between the asteroid rising above the horizon and sunrise is, therefore, very small.
