# Apophis

*In the Solar System*

A near-Earth asteroid about 340 metres across, here because on 13 April 2029 it will pass Earth about 32,000 km above the surface (38,000 km from the centre) - inside the ring of geostationary satellites and closer than any asteroid of its size has been predicted to come. It will be visible to the naked eye from Europe and Africa. Early orbits gave it a small chance of hitting in 2029 and again in 2036; radar and years of observations have ruled both out for at least a century. Earth's gravity will reshape its orbit and may change how it spins, and OSIRIS-APEX is due to be there to watch.

Distances and speed are computed from JPL Horizons trajectories and are true of 2026-11-14, changing at the rate given beside each. The interpolation itself is good to a few kilometres; what ages these figures is the date, not the arithmetic.
