The Earth has two moons?

Scientists believe that the moon is not the only object that always accompanies Earth during its rotation around the Sun. Currently, close to our planet is also observed in 2010 TK7 Trojan asteroid. Does she deserve to be called a second moon? 
Asteroid identification number TK7 has a diameter of about 300 meters and is known to be a group of Trojan asteroids. Such objects are also around Jupiter, Mars and Neptune. But TK7 is the first such asteroid occurring in the vicinity of Earth. 
At the moment there are about 80 million miles from us. At first, astronomers feared Trojan collision with our planet, but after making the necessary calculations of trajectories of asteroids, it appeared that the collision with the Earth will never happen. NASA plans to send astronauts in the future to examine TK7. However, such an undertaking would be very expensive and as long as NASA invests in its other projects. Scientists say the Earth has always been accompanied by an asteroid. But all the previous objects, after several laps of the planet, burst from its gravitational field and flew into space. But this time we are dealing with the asteroid, which will accompany us for many hundreds of years. In addition, it orbits the Sun in an orbit similar to ours. 


Will be there second trip on the moon?:))))
