The Arecibo Observatory, which was closed due to threats caused by hurricane Maria, fully restored its work and has enabled researchers to obtain images of near-earth asteroid Phaethon. As reported on the website NASA, the images were obtained during a convergence of the celestial body with the Earth in December of this year.
The new observations allowed to establish that the Phaeton is shaped like the asteroid Bennu. Diameter of a celestial body is six kilometers per kilometer more than researchers previously thought. The Phaeton is the second largest near-earth asteroid that entered in the list of “potential threats”, that is, a collision with them may cause significant damage to our planet.
The Phaeton was opened on 11 October 1983. Dust, which causes a meteor stream Geminids, formed this asteroid.
Previously, scientists have said that potentially dangerous for the Earth asteroids are invisible to ground-based telescopes. To such conclusions researchers came after analyzing the data of the detections of near-earth objects to several observatories.
