Three years ago, the huge and dark comet, TB145, passed over the night before Halloween, shocking science and astronomy fans. It happens again at the point closest to our planet today.
Three years ago, a huge dark asteroid approached the Earth. It was just before Halloween began. It shocked the entire scientific community and astronomy fans.
When NASA filmed it, he could not believe what he was seeing: a skull-shaped asteroid. They soon dubbed him an asteroid of death or an asteroid of Halloween.
But it's not a visual effect or a skeleton-like asteroid. It is 2015 to claim that the official name of this object, which is as dark as coal and claimed by many scientists, is not an asteroid but a dead comet. TB145.
It was discovered in 2015 by the Pan-STARRS telescope in Hawaii, USA and attracted the attention of astronomers. Because they saw a very close proximity to the earth on October 31 night. It is only 486,000 kilometers, 1.3 times the distance that separates us from the moon.
"It has two depressions that can be interpreted by the eye," said Rüdiger Jehn of the European Space Operations Center (ESOC) in Darmstadt, western Germany. "But we have a lot of imagination," he added.
The asteroid is 600 meters in diameter and the two craters are about 100 meters each, he said. Despite its proximity, 2015 TB145, which first approached the Earth three years ago, is not dangerous. Fortunately, in the next 500 years, skimming will never happen again.
He explains that this object can travel only about 40 million kilometers away from Earth and can only be seen as a point of light with a giant telescope. Experts at the European Space Agency (ESA) said, "But we can continue to provide science fiction fans with fun."
Sven Melchert, chairman of the Friends of the Stars in the South of Hessen, Hessen, notes that the "reconstructed expression based on radar observations" recorded in October 2015 is similar to the skull.
It is expected to take place again in 2021 because the asteroid takes 3 or 17 days to enter the orbit around the sun. It will not be relatively close to Earth by 2085.
"Due to its low brightness and distance it can only be seen with large telescopes such as NASA or ESA's routine tracking." Sinc Agency Astronomer Pablo Santos-Sanz, explains the Andalusian Institute of Astrophysics (IAA-CSIC) Writer
Like comets and asteroids, it was also formed during the creation of the solar system 460 million years ago, so researching it can provide clues as to the origin of our cosmic source and how it evolved in the present.
