Halloween asteroid returns to Earth
In the new 2018 to our planet again close the “dead” comet, shaped like a human skull
31 Oct 2015 closer to the Earth asteroid 2015 TB145, from certain angles, resembles a human skull. Since the day of its closest approach to our planet on Earth celebrated Halloween, an asteroid was named just like the occasion. Even a scientific article where astronomers from Hungary, Germany, Spain and Poland described the results of their observations, called “Hellouinsky the asteroid at a distance comparable to the distance to the moon.” It is reported by Popular mechanics.
All saints ‘ Day asteroid really flew to the Earth at a distance of only 1.3 times greater than the distance from the earth to the moon.
However, with the orbital period of 1112 days TB145 cannot be called a regular at our hellouinsky party; he returns to Earth every three years, always in different dates. The next visit will take place in early November 2018.
Diameter TB145 ranges from 625 to 700 meters. He almost does not reflect light, its albedo is approximately equal to the albedo of coal. But he radiates warmth: the image was taken in the infrared range.
The nature of the rotation of the asteroid indicates that he was once a comet, but lost all volatile substances, and reserves of gas and dust tail.
