   How far is Apophis from Earth?

   • Apophis is about 1,100 feet (340 meters) in width. It’s expected to safely pass close to Earth – within 19,794 miles (31,860 kilometers) from our planet’s surface – on April 13, 2029. This will be the closest approach to Earth by an asteroid of this size that scientists have known about in advance.

   How far will asteroid 99942 Apophis be from Earth?

   • On 13 April 2029, the asteroid 99942 Apophis will pass less than 32 000 km from Earth’s surface. Roughly 375 m across on average, Apophis will, for a short time, be closer to Earth than telecommunications satellites in geostationary orbit and visible in the night sky to the naked eye from parts of Europe, Africa and Asia.

   How big is the asteroid Apophis?

   • Estimated to be about 1,100 feet (340 meters) across, Apophis quickly gained notoriety as an asteroid that could pose a serious threat to Earth when astronomers predicted that it would come uncomfortably close in 2029.

   How close will Apophis be to Earth in 2029?

   • On April 13, 2029, Apophis will pass less than 20,000 miles (32,000 kilometers) from our planet’s surface – closer than the distance of geosynchronous satellites. During that 2029 close approach, Apophis will be visible to observers on the ground in the Eastern Hemisphere without the aid of a telescope or binoculars.

   Why is Apophis a 'near-Earth asteroid'?

   • Apophis formed in the main asteroid belt between Mars and Jupiter in the early days of our Solar System, roughly 4.6 billion years ago. Gravitational interactions with the planets, primarily Jupiter, over millions of years have altered the orbit of Apophis. It now crosses Earth’s orbital path and is therefore classified as a ‘near-Earth asteroid’.

   Will asteroid Apophis ever hit Earth?

   • That was until a close flyby of the asteroid — a space rock that is almost as wide as the Empire State Building is tall — in March 2021 allowed NASA scientists to determine Apophis actually won't hit the Earth for at least 100 years.

   Apr 29, 2019 · But it won’t be a satellite or an airplane—it will be a 340-meter-wide near-Earth asteroid called 99942 Apophis that will cruise harmlessly by Earth, about 19,000 miles (31,000 km) above the surface. That’s within the distance that some of our spacecraft that orbit Earth.
