On April 13, 2029, asteroid Apophis passes about 20,000 miles from Earth. NASA's OSIRIS-APEX meets it in June 2029 to see how that close pass changes it.

Near-Earth asteroid Apophis will safely pass about 20,000 miles (32,000 km) from Earth's surface on April 13, 2029, closer than many satellites in geosynchronous orbit. NASA says there is no risk of Apophis hitting our planet for at least 100 years. OSIRIS-APEX, the renamed OSIRIS-REx spacecraft, will rendezvous with Apophis in June 2029 to study how Earth's gravity changes its orbit, spin and surface.

Knowing how a stony asteroid reacts to a close pass is exactly the kind of knowledge planetary defense needs.
