The Story Of Asteroid 1566 Icarus: A Near Miss With Earth
Introduction
Asteroids have been fascinating celestial objects whose study has greatly enhanced our understanding of the universe. And though they have played a critical role in the formation and evolution of the solar system, they have also presented a potential threat to Earth. This article focuses on asteroid 1566 Icarus, which, at one point, came dangerously close to Earth.
The Discovery of Asteroid 1566 Icarus
Discovery and Naming
Asteroid 1566 Icarus was discovered on June 22, 1949, by Walter Baade at the Mount Palomar Observatory in California. Its discovery represented a significant milestone in the scientific world since it was the first asteroid observed with an orbit that lies entirely within the orbit of the Earth.
The asteroid was named after Icarus, a figure from Greek mythology who flew too close to the sun and fell to his death. The name Icarus seemed fitting since the asteroid's orbit took it dangerously close to the sun and Earth.
Physical Characteristics
Asteroid 1566 Icarus is classified as an Apollo asteroid, meaning its orbit crosses that of Earth. The asteroid's orbit is highly eccentric and takes it as close as 0.19 astronomical units (AU) to the sun and as far as 1.08 AU from the sun. Thus, its orbit extends from just inside the orbit of Venus to just beyond the distance of Mars from the sun.
The asteroid is estimated to be about 1.4 kilometers in diameter and rotates once every 2.2 hours.
Asteroid 1566 Icarus's Close Approach to Earth
The Near Miss of 1968
On June 14, 1968, asteroid 1566 Icarus also made a record-breaking close approach to Earth, coming within 0.042482 AU (6,356,800 km) of the planet. This is less than one-sixth of the average distance between the Earth and the Moon.
The asteroid's near-miss with Earth was momentous and marked the first time that astronomers were able to make radar observations of an asteroid.
The Accuracy of the Prediction
The asteroid's orbit made it difficult to predict its position accurately for its next close approach. As a result, several attempts were made to refine the probability of the asteroid's collision with Earth. However, during the subsequent close approaches in the 1970s and 1980s, the asteroid's orbit turned out to be different from what was predicted.
However, the accuracy of Icarus's orbit improved with improved technology, and further close approaches were accurately predicted.
What Would Happen If Asteroid 1566 Icarus Collided with Earth?
The Chances of Impact
The chances of asteroid 1566 Icarus colliding with Earth are low but not negligible. The asteroid has not been observed to cross the Earth's orbit since 1968, and its current orbit has been mapped accurately using radar. Therefore, the asteroid is considered to pose no significant threat to Earth in the foreseeable future.
However, it should be noted that any potential impact from an asteroid of this size would result in significant destruction, as it could release energy equivalent to that of several nuclear bombs.
The Consequences of Impact
In the event that asteroid 1566 Icarus were to collide with Earth, the consequences would depend on various factors such as where it hit, the angle of impact, and the speed at which it was traveling. However, experts predict that the impact would generate a crater more than 10 kilometers across and cause widespread devastation and loss of life.
