18.95 ± 0.15[11] 99942 Apophis (provisional designation 2004 MN4) 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, 13 April 2029.
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 ...
Astronomer Paul Wiegert had found a scenario in which Apophis could be sent careening into Earth in 2029. But we’d have to be extremely unlucky. Asteroid Apophis has the tiniest chance of ...
Gravitational keyhole. A gravitational keyhole is a tiny region of space where a planet's gravity would alter the orbit of a passing asteroid such that the asteroid would collide with that planet on a given future orbital pass. The word "keyhole" contrasts the large uncertainty of trajectory calculations (between the time of the observations of ...
Apep (Ancient Egyptian: ꜥꜣpp), also known as Aphoph (/ ə.ˈfɒf /, Coptic: Ⲁⲫⲱⲫ, romanized:Aphōph) [ 1 ] or Apophis (/ ə.ˈpɒ.fɪs /; Ancient Greek: Ἄποφις, romanized:Ápophis), is the ancient Egyptian deity who embodied darkness and disorder, and was thus the opponent of light and Maat (order/ truth). Ra was the bringer ...
Keeping an eye on Apophis during and after its close approach to Earth will enable scientists to see whether there are any shifts in its orbit that could affect the likelihood of it hitting Earth ...
OSIRIS-REx in Launch Configuration. OSIRIS-REx[ a ] was a NASA asteroid-study and sample-return mission that visited and collected samples from 101955 Bennu, a carbonaceous near-Earth asteroid. [ 14 ] The material, returned in September 2023, is expected to enable scientists to learn more about the formation and evolution of the Solar System ...
The Costa Concordia sank into the ocean on January 13, 2012. ... the closeness of the asteroid could cause damage on its surface — the gravity of Earth might cause avalanches on Apophis.
