It will not be so close; it will do so at a distance of about 38 million kilometers, ie a quarter distance between Earth and the Sun, about
After passing through the Earth on 31 October to just 480,000 kilometers of us, a team of astronomers from NASA processed radar images of the asteroid, obtaining high-resolution snapshots called 2015 TB145, “asteroid Halloween” or “Great Pumpkin” due to both its form and in such a particular way as the celebration of Halloween day.
To get the best images of the asteroid (4 meters per pixel), the scientists used the giant terrestrial telescopes to bounce radar signals in spherical rock about 600 meters in diameter 100 meter telescope of the National Radio Astronomy Observatory in Green Bank, West Virginia (USA), which revealed areas of the asteroid’s surface not seen before: bright spots (maybe rocks), highly charged cavities and a number of features “that could be peaks” explains Lance Benner of the Jet Propulsion Laboratory of NASA in Pasadena, California (EU)
Benner says that “the images are clearly different from the radar images Arecibo obtained on 30 October and are probably the result of seeing the asteroid from a different perspective, in its rotation period of three hours. “
2015 TB145 will fly over the Earth. This time in September 2018, but will not be so close; it will do so at a distance of about 38 million kilometers, ie a quarter distance between Earth and the Sun, about
