Since 2019, the possibility that a 340 meter asteroid –Apophis– could impact Earth. They named him as the God of chaos due to its size and presumed danger. They even claimed that its impact could be 15 thousand times greater than the Hiroshima bomb. For this reason, the images that were captured of this asteroid near planet Earth were recently surprising.
According to what the specialists had first established, there was a probability that on April 13, 2029 the asteroid would impact the planet. However, more recent studies have dismissed the impact.
However, because specialists already have an established route, the God of Chaos was captured for the first time in European telescopes.
It was thanks to the Virtual Telescope Project that the image of the asteroid Apophis was taken with the Elena robotic telescope unit, where there was a 300-second exposure of the sky. The captured image shows the asteroid as a small white dot. Although it seems small, the reality is undoubtedly different.
On March 6, the asteroid Apophis will be brighter for telescopes, as its distance will be closer to our planet. It is estimated that it will be 15 million kilometers from the planet Tiera.
Previously, NASA had reported that Apophis would get very close to Earth on April 13, 2029; Without posing a threat to our planet, that day is expected to be visible to the naked eye in the sky.
Researcher Dave Tholen and his collaborators at the University of Hawaii Institute of Astronomy (IfA) have announced the detection of the Yarkovsky acceleration on the near-Earth asteroid Apophis.
This acceleration arises from an extremely weak force on an object due to non-uniform thermal radiation. This force is particularly important for the asteroid Apophis, ‘God of Chaos’, as it affects the probability of a ground impact in 2068.
All asteroids need to re-radiate the energy they absorb from sunlight as heat to maintain thermal equilibrium, a process that changes the asteroid’s orbit slightly. Before the detection of the Yarkovsky acceleration at Apophis, astronomers had concluded that a potential impact with Earth in 2068 was impossible.
