Cosmic Companion: A Mysterious Asteroid to Shadow Earth for Two Months

Discovered just a month and a half ago, on August 7, an asteroid is now approaching Earth’s orbit and will arrive on Sunday, September 29.

For about two months, this small cosmic companion will move parallel with Earth as both orbit the Sun. This unusual celestial visitor is a Near Earth Object (NEO), a category that includes small celestial bodies like asteroids and comets.
