Asteroid Apophis Passes Inside Satellite Orbit
A 340-metre asteroid passes about 32,000 km from Earth, closer than geostationary satellites and visible to the naked eye from Europe and Africa.
- Apophis will pass Earth on 13 April 2029 at about 32,000 km (20,000 miles) from the surface, closer than geosynchronous satellites, and will be visible to the naked eye in the Eastern Hemisphere[2][3]
- Wikipedia gives the distance as 0.000254 AU (38,015 km, uncertainty ±3.3 km, presumably from Earth's centre), after which it changes from an Aten to an Apollo-type orbit[1]
- Size is estimated at about 340 m (1,100 ft); radar suggests an elongated, possibly bilobed shape and a roughly 30.4-hour tumbling rotation[1][3]
- NASA says there is no impact risk for at least 100 years; radar in March 2021 ruled out 2068 and it was removed from the Sentry table[2][3]
- NASA redirected OSIRIS-APEX to study Apophis at the 2029 closest approach[2]
- Discovered 19 June 2004 at Kitt Peak by Tucker, Tholen and Bernardi; the 2029 encounter could change its spin and cause "asteroid quakes"[1][2][3]

NASA's[3] own account states "Asteroid Apophis will safely pass close to Earth on April 13, 2029," an exact match to the pin's stored date.

NASA's[2] JPL corroborates independently: "On April 13, 2029, the asteroid Apophis will pass less than 20,000 miles... from our planet's surface," confirming the same date as the pin.
