‘God of Destruction’ asteroid Apophis will come to Earth in 2029 — and it could meet some tiny spacecraft

In just under half a decade, a 1,000-foot-wide (305-meter-wide) asteroid named after the Egyptian god of chaos and destruction, Apophis, will pass within 30,000 miles (48,300 kilometers) of Earth. Scientists don’t intend to allow the rare close passage of a space rock of this size to go to waste.

On April 13, 2029 — a Friday, no less — when Apophis, formally known as (99942) Apophis, makes its closest approach to Earth, it will become so prominent over our planet that it will visible with the unaided eye. NASA’s OSIRIS-APEX spacecraft (once known as OSIRIS-REx) will be on hand to meet the near-Earth asteroid (NEA) personally. But, if things shape up, that NASA mission could be joined by a host of little satellites during its rendezvous.

Under the auspicious “NEAlight” project, a team from Julius-Maximilians-Universität Würzburg (JMU) and led by space engineer Hakan Kayal has revealed three concepts for such spacecraft. Each of the suggested satellites will aim to exploit this asteroid passage because Earth experiences just once such event every millennium. The goal? To collect data that could help scientists better understand the solar system, and perhaps even aid in the development of defense measures against dangerous asteroids.
