An asteroid known as 2016 HO3 is locked in "a little dance" with Earth according to NASA. This asteroid isn't as close to Earth as our primary moon, however its orbit is being affected by Earth's gravitational pull.
NASA says that the asteroid has an irregular orbit. It drifts between 38 and 100 times the distance of Earth's predominant moon. It is also bouncing or bobbing up and down across our planet's orbital plane.
Even though this asteroid is much smaller than our primary moon, it is still being affected by Earth's gravitational pull, making it a temporary second moon. So for the time being, you can be proud to be part of a planet with two moons!
