The 2015 TB145 asteroid resembled a skull when it passed on our planet three years ago on Halloween. But now, the object may be a little less "humble" because its shape may have changed since then.
"This time it is not close enough (Earth) to be bigger than a bright spot," said Paul Chodas, director of NASA's Jet Propulsion Laboratory.
The asteroid was previously estimated to be 2,000 feet in diameter. However, asteroids change shape over time because they break against other celestial objects and break.
In addition, giant rock will not be closer before November 11, well after Halloween.
NASA says that the asteroid is most likely a "dead" comet that once spit out debris on the solar system. In spatial discussions, this means that it has "eliminated its volatiles", which would produce the visible tail of some comets.
The asteroid was discovered on October 10, 2015 by the Pan-STARRS-1 telescope (panoramic observation telescope and rapid response system) of Haleakala, on the island of Maui.
