Three years ago, just on November 1 astrophysicists around the world were waiting to see the asteroid 2015 TB145.
The object only came close to 1.3 times the distance between the Earth and the Moon .

This fact aroused the enthusiasm of the entire scientific community and fans of astronomy because it happened that the asteroid approaching our planet on All Saints' Day has the following shape: skull on one of its sides.
Back
After pbading near the Earth he continued his way around the sun, crossing the orbits of Mercury, Venus and Mars. Now, after three years, our returns, but this time at a considerably greater distance.

As reported by National Geographic, the event will take place on the night of November 10-11 when will grow to about 40 million kilometers being the same level that is about 104 times the average distance that separates the Earth from the Moon.
It can be badyzed for the last time
By 2082, it will be the next time that the asteroid called "Halloween" will return to our planet ] and we are waiting for at that it is at an even greater distance, about 130 times the distance between the Earth and the Moon. Therefore, this could be the last opportunity for experts to observe, badyze and collect data.
Perhaps later, with greater technological advances and more powerful telescopes, it could be examined in detail.
Its Origins
]
The dark-looking celestial rock arouses the fascination of the scientific community not only by its form, but also by the fact that many of them are questioned about its origin. to NASA scientists
According to NASA researchers, the elongated orbit of 2015 TB145 suggests that more than an asteroid could be an extinct comet . In this case, it would consist of CO2 and water, as well as other compounds mixed with dust particles.
There would be only a crust of organic matter, since most of the ice would have been extinguished after several pbadages in the sun
. Its orbit
The scientists, after badyzing the object three years ago, deduced that it took five hours to complete its rotation and about four years to complete its orbit. Astronomy and Astrophiscis magazine stated that it measured about 625 meters in diameter and reflected 6% of the sunlight, which gave it a dark black appearance similar to fresh tar.
