In 2036, Apophis will approach the Earth at a third the distance of the Sun in both March and December, [ 1] but this is about the distance of the planet Venus when it overtakes Earth every 1.6 years. On April 12, 2068, the nominal trajectory has Apophis 1.87 AU (280 million km) from Earth. [ 15] .

Apophis is a space rock about 1,100 feet (340 meters) across. Calculations in recent years have proven the asteroid will safely glide past Earth in both 2029 and 2036. In 2029, Apophis should pass at a nominal distance of 19,662 miles (31,643 km) from the Earth’s surface. That’s in contrast to the moon’s average distance of about 238,000 miles (384...
Astronomers at Kitt Peak National Observatory near Tuscon, Arizona, discovered Apophis on the evening of June 19, 2004. The team of Dave Tholen, Fabrizio Bernardi, and the late Roy Tucker were searching for asteroids low in the western sky. They were specifically looking for objects in the direction of the sun. The asteroid they found was originall...
It took several more years of studying this asteroid to learn it would not strike Earth in 2029. The fact is, an asteroid’s orbital path can be changed slightly, every time it passes near another astronomical object. And it can change by what’s called the Yarkovsky effect, a minor push on the asteroid, caused by sunlight. Both are known effects. Bu...
But what about the next close approach in 2036? That possibility was eliminated in 2013. In early March of 2013, all eyes turned toward Apophis as the asteroid made a relatively close sweep (though not nearly as close as in 2029) to our planet on March 6. The Goldstone Deep Space Communications Complex tracked the asteroid for about two weeks aroun...
This new analysis means that Apophis is no longer on the Sentry Impact Risk Table, which is a list of objects that pass so close by Earth that astronomers have not yet been able to rule out a possible strike. This campaign not only helped us rule out any impact risk, but it also set us up for a wonderful science opportunity in 2029. The images seen...
The Virtual Telescope Project, based in Rome, Italy, captured asteroid (99942) Apophis on March 2, 2021. The asteroid shows as a dot – while the stars around it show as streaks – because the telescope was tracking the asteroid’s motion. It is moving through space with respect to Earth at 2.894 miles/sec (4.658 km/sec). Image via Virtual Telescope. ...
Astronomers in Hawaii studied how Yarkovsky acceleration, or pushes due to sunlight, would change Apophis’ orbit. In some instances, acceleration – a changein an object’s speed and direction through space – can help avoid a collision. Studies of Yarkovsky acceleration as related to asteroid Apophis suggest this is the case for this asteroid. Astron...
Apophis is now in a part of the sky that is not observable from Earth. It will remain so until we see it again in 2029. NASA’s OSIRIS-REx was a historic space mission, which brought the first samples from asteroid Bennu back to Earth. The spacecraft remains in good condition and still has a quarter of its fuel left. So NASA has redirected the craft...
Mar 26, 2021 · When Apophis made a distant flyby of Earth around March 5, astronomers took the opportunity to use powerful radar observations to refine the estimate of its orbit around the Sun with extreme precision, enabling them to confidently rule out any impact risk in 2068 and long after.
Jan 9, 2013 · After tracking asteroid 99942 Apophis with NASA's giant Goldstone radar dish, astronomers are now certain that the threatening asteroid has essentially no chance of striking Earth in 2036.
Dec 14, 2022 · Although Apophis will not hit Earth anytime soon, the asteroid will make a close encounter with our planet on April 13, 2029, when it will pass within just 19,000 miles (31,000 kilometers).
