Earth has more than one moon?

In a paper called "The Number of Earth's Natural Satellites," astronomers say that the Earth has a second moon at certain times.

>>>The moon is getting smaller

Although these are only small moons, the scientific significance of this discovery is truly phenomenal. Think about this: instead of sending adventurers to asteroids, we now know there are planets around Earth's orbit, studying these planets in the solar system will easier.

Mikael Granvik, Jeremie Vaubaillon and Robert Jedicke from Cornell University calculated the number of natural satellites flying around the Earth. These moons secretly came and went quietly without notice, but at least once they discovered. In fact, their calculations were confirmed by a previous observation: a white titanium object was discovered orbiting the earth when surveyed Catalina, Arizona in 2006.

The result we obtained is consistent with the 2006 planet RH120, a few meter diameter object was recorded for about a year starting in June 2006. This is essentially a small asteroid attracted by Earth's gravitational field. This planet rotates like a second moon until 2007, when it leaves the orbit of our planet. This study proves that, even when not easily detected, these small moons come and go often, around the Earth for about 10 months and then disappear.

However, how often do these 'temporary moons' appear? According to scientists, this phenomenon occurs quite often. "At any time, at least one natural satellite with a diameter of 1 meter orbits the Earth" - Granvik, Jeremie Vaubaillon and Robert Jedicke wrote in online physics magazine ArXiv.org. In other words, at this time, our planet may be having a secret moon orbiting around.

Since there are always small moons flying around the Earth, astronomers can study to detect them. Once discovered, we could send some astronauts up there to analyze it instead of having to send an entire crew to a distant planet. Researching information about the solar system by tracking small planets flying around the Earth really saves a lot of costs.
