99942 Apophis (provisional designation 2004 MN 4) is a near-Earth asteroid and a potentially hazardous object, 450 metres (1,480 ft) by 170 metres (560 ft) in size, [3] that caused a brief period of concern in December 2004 when initial observations indicated a probability of 2.7% that it would hit Earth on Friday, April 13, 2029.
The sizes of the charts show the relative sizes of the asteroids to scale. For comparison, the approximate size of a person is also shown. This is based the absolute magnitude of each asteroid, an approximate measure of size based on brightness. Abs Magnitude 30 and greater. Silhouette of man standing and facing forward (size of a person for ...
A menacing asteroid named Apophis is projected to have a close encounter with Earth in 2029, but scientists have long ruled it out as an impact risk. Asteroids safely fly by Earth all the time ...
A space rock the size of a cruise liner will closely pass Earth in April 2029. While the asteroid Apophis won’t hit Earth, two spacecraft may tag along.
In December 2009 Roscosmos Russian Federal Space Agency director Anatoly Perminov proposed a deflection mission to the 325-metre-wide (1,066 ft) asteroid 99942 Apophis, which at the time had been thought to pose a risk of collision with Earth. [14] [15]
In a bit of ominous news befitting a Friday the 13th: It turns out that the asteroid Apophis could have a very small chance of colliding into Earth in five years, when it is expected to make a ...
The asteroid will pass 0.00516 AU (772,000 km; 480,000 mi) from Earth on 27 December 2022, [4] [5] allowing a refinement to the known trajectory. The uncertainty region in 2013 suggested that the asteroid could have passed inside the orbit of the Moon in 1907, but is now known to have passed about 0.01 AU (1,500,000 km; 930,000 mi) from Earth ...
But as of March 2021, NASA has confirmed that there is absolutely zero chance the space rock known as 99942 Apophis will strike this planet for at least 100 years. So, phew. So, phew. Cross that ...
