Asteroid and Earth Orbits Intersect

Deimos-Space

In this plot, the asteroid is the yellow dot, and Earth is green; the two orbits intersect twice per year. A preliminary orbit calculation shows that 2012 DA14 has a very Earth-like orbit with a period of 366.24 days, just one more day than our terrestrial year, and it ‘jumps’ inside and outside of the path of Earth two times per year.
